Real Statistics Resource Pack

The Real Statistics Resource Pack contains a variety of supplemental functions and data analysis tools not provided by Excel. These complement the standard Excel capabilities and make it easier for you to perform the statistical analyses described in the rest of this website. 

We now explain how to download and install the Real Statistics Resource Pack for use with Excel 2010, 2013, 2016, 2019, 2021 or 365 on Windows. If you are using Excel 2007 click here. If you are using Excel 2003 or a prior version of Excel click here. If you are using Excel for the Macintosh click here.

Keep in mind that there are also two versions of Excel, at least for Excel 2010, 2013, 2016, 2019, 2021 and 365, the 32-bit version and the 64-bit version. Most people use the 32-bit version. The Real Statistics Resource Pack works in both versions of Excel.

Download

Real Statistics Resource Pack for Excel 2010, 2013, 2016, 2019, 2021 or 365 for Windows

Two versions of the software are available. The first provides help support (via Insert Function fx) for Real Statistics worksheet functions but can slow down certain Excel operations. The second version omits this support but does not degrade Excel operations.

Both versions of the software are compatible with all Windows releases of Excel from 2010 until the present. After downloading the software make sure that you install the software as described below.

Downloading either resource pack means that you accept the License Agreement.

Solver Installation

Before trying to install the Real Statistics Resource Pack make sure that Excel’s Solver is installed on your computer. You can check this as follows:

  1. Open up a blank Excel spreadsheet
  2. Press Alt-TI (i.e. hold down the Alt key and press the T and I keys).
  3. On the dialog box that appears make sure that the Solver add-in is checked. If not, check it and click on the OK button.
  4. If the Solver add-in was not checked you need to close the Excel file before proceeding to the Real Statistics installation.

You can also accomplish step #2 by selecting Developer > Add-ins|Excel Add-ins.

Real Statistics Installation

Once you have downloaded the Resource Pack and made sure that Solver is installed, you need to install the Real Statistics Real Pack using the following steps:

  1. Move the Resource Pack to where you want it located on your computer (see our recommendation below). Caution: Once you install the resource pack at a particular location it will be more difficult to move it later.
  2. Open Excel, but don’t try to open the XRealStats.xlam or XRealStatsX.xlam file that you downloaded earlier.
  3. Select File > Help|Options > Add-Ins and click on the Go button at the bottom of the window (see Figure 1). Alternatively, you can simply press Alt-TI (i.e. hold the Alt key down and simultaneously press T followed by I) and the dialog box shown in Figure 2 will appear.

    Add-in dialog box
    Figure 1 – Add-Ins dialog box 1
  4. Check the Xrealstats or Xrealstatsx option on the dialog box that appears (see Figure 2) and click the OK button. NOTE: If you have previously activated a different version of the Real Statistics software you must uncheck the option corresponding to that version.
  5. If this option doesn’t appear, click on Browse to locate and then choose the xrealstats.xlam or xrealstatsx.xlam file. Then complete step 4 as described above.

Where to place the Real Statistics Resource Pack

While you can place the Real Statistics Resource Pack anywhere on your computer, we recommend that you put the file in the following folder:

C:\Users\user-name\AppData\Roaming\Microsoft\AddIns

where user-name is your username in Microsoft Windows. Since some of these folders are hidden, you may find it convenient to enable showing hidden folders. For example, in Windows 10 or 11 you can do this by opening Settings and then typing Show Hidden Files and Folders in the search field. Next, check on the Show hidden files, folders, and drives option in the dialog box that appears, and then click on the OK button.

Installation of Upgrades

Once you have installed the Real Statistics Resource Pack as described above, to install a new version of the software you don’t need to repeat these steps. You only need to delete the previous version of the resource pack and put the new version of the software in the same location as the previous version.

Troubleshooting

If there is a problem during the installation try one or more of the following:

  1. If Excel is running, close it. Find the file with the Real Statistics add-in. Right-click on the file and click on the Properties option from the menu that appears. Towards the bottom of the General tab of the Properties window, you will see the security message “This file came from another computer and might be blocked to help protect this computer”. Next to this message is the Unblock checkbox. Make sure this is checked and press the OK button. Start Excel.
  2. Click on Options from the File ribbon and then choose the Trust Center option on the left side. Next, click on Trust Center Settings …. Now, click on the Macro Settings option on the left side and make sure that it is Disable all Macros with Notification. Also, click on the Trusted Locations option on the left side and click on the Add New Location… button to add the folder that contains the XRealStats or XRealStatsX file as a trusted location.
  3. Try opening a blank Excel worksheet and press Alt-TI. Uncheck the Xrealstats add-in and close Excel. Now open a blank Excel worksheet and press Alt-TI. This time check the Xrealstats add-in

Most importantly, remember that Solver must be installed. To check this, press Alt-TI and make sure that Solver (as well as Xrealstats or Xrealstatsx) is on the list of add-ins with a checkmark next to it.

Real Statistics Functions

Once you have installed the Real Statistics Resource Pack you can use the Real Statistics functions in the same way as you use the built-in worksheet functions supplied with Excel. These functions are described throughout the rest of this website. A complete list of these functions can be found on the Tools menu of the website (or at Real Statistics Software Capabilities).

Real Statistics Data Analysis Tools

You can access the Real Statistics data analysis tools in one of the following ways, as described in Accessing Real Statistics Data Analysis Tools:

  • By pressing Ctrl-m or
  • By clicking on an icon on the Add-Ins ribbon or
  • By clicking on an icon on the Quick Access Toolbar or
  • Via the Macro dialog box

A dialog box will now appear that lists all the available Real Statistics data analysis tools.  You need to choose one of the data analysis tools from this list.

A dialog box will then appear as described in Real Statistics Data Analysis Tools which enables you to specify your input data and choose from available options. You can also access Help to get more information about the selected data analysis tool.

A complete list of Real Statistics data analysis tools can be found in Real Statistics Data Analysis Tools.

Uninstalling the Real Statistics Resource Pack

  1. Open Excel
  2. Press Alt-TI
  3. Uncheck the Xrealstats or Xrealstatsx option on the dialog box that appears and click the OK button.
  4. Close Excel and delete the file that contains the Real Statistics Resource Pack.

  1. Dear Dr. Zaiontz, (Charles)
    What an amazing site! I’ve been looking for weeks for resources for my students on the web. There are tons of introductory statistics, but very little for more advanced statistics such as logistical regression analysis. Thank you thank you for making this available. I’ve downloaded the resource pack and gotten it to work on my computer and my version of Excel, and I downloaded some of your datasets to use with my students. You are terrific!!

    A couple of points that might be helpful to others:
    First, the add-on doesn’t appear to have “Logistic Regression” anymore. Now it is called “Logistic and Probit Regression” and you need to click on the Reg tab to find it. (It appears the add-on now has many more features and functions than when you made the video.)
    Second, if when I tried to embed the logistic regression results in the same sheet I got an error. I had to choose NEW.
    Also, if you tell it not to show the item details but unhide the ROC table, you get errors. You need to show the item details in order to unhide the ROC table.
    But given these minor issues, I am amazed at how well this add-on works. The next test is getting it to work at the university with all the extra security software they run, but in any case I will be able to demonstrate it on my machine because I have admin rights.
    Once again – thanks ever so much for making this available.

    • Hello CJ,
      Thank you very much for your kind words. A lot of teachers are using Real Statistics since it is free and can be used readily by most students. Since it is based on Excel, it is also easy for the students to get familiar with the steps in the analyses.
      1. I didn’t produce the You Tube videos. Other users did created these.
      2. Can you send me an Excel file with your data and results so that I can figure out what is causing these errors?

  2. Hello Charles,
    After the pack is installed, I’m sure the XRealStats add-in and the solver add-in are both added in Excel’s Add-ins. But, I can’t find the Real Statistics in My Add-ins after I reopen Excel! How can I solve this problem?

      • Hello Charies,
        I appreciate for your reply! Just now, I already found out and solved the problem, that the pack wasn’t in the trusted location of Excel.
        Thank you, anyway!

  4. While I could not get RealStats to install on my Japanese Excel 2007, as mentioned in a previous post (which there is no need publish — as you see fit) RealStats has installed Really easily on my Japanese Excel 2013 (once I had right clicked on the file > Properties and checked the box to allow software from other computers).

    Thank you very much indeed for this wonderful software.

  14. I’m getting an error message on Excel when I try to download saying “microsoft has blocked macros from running because the source of this file is untrusted”. it gives me the option to click “disable macros” which ive clicked on and it still didnt work so how can I get around this?
    Thanks,
    Mark

    • Hello Mark,
      Clicking on the disable macros option will disable the software. Instead, please follow the Troubleshooting instructions on this webpage. This will resolve this obstacle which Microsoft introduced a couple of years ago for security reasons.

  17. Why is there a limit of 14 on the lag for the cross correlation analysis?

    I wasn’t sure of the lag time and used interpolation on my curves to get an exact place.

    this forced me to run the function multiple times to get the answer.

    The hard limit of 14 seems VERY odd. Otherwise I love this package. You really should have DOWNLOAD BUTTONS rather than hyperlinks

    Reply

    • Hi Steve,
      Thanks for your suggestions.
      If I remember correctly 14 is an arbitrary limit. Do you have a different suggestion?
      Are you referring to the links on the webpages where you can download the software?

  18. Hello.
    If you’re still having problem installing or using RealStat, you can do the following, for those using Microsoft Windows 10.
    Download the RealStat resource pack and install (copy and paste) in this path: c:>Program Files>Microsoft Office>root>Office16>Library
    Create a folder in the Library, name it RealStat (or any other name) and put the RealStat resource pack (XRealStats.xlam) in it.
    Also, download the RS_QAT.xlsm and paste it in the folder containing XRealStats.xlam. Please note that this folder is in library (as shown in the path above).
    Now open Excel work book and follow this path, File>Options>Add-ins. In box beside Manage (located at the bottom of the Add-ins page), ensure it’s displaying Excel Add-ins, then click Go… A dialogue box showing available Add-ins is displayed. If XRealStats is showing on the list, check the box beside it and click Ok. Otherwise, click the Browse box to browse the XRealStats (following the location path), select the XRealStats (not RS_QAT.xlsm) and it will appear among the list of available Add-ins. Check the box beside it and then click OK. The dialogue box will be closed and the RealStats is ready for use.
    To use this statistical package, open any excel work sheet containing your data, on the top menu bar of the work sheet, locate Add-in (it’s usually between View and Help), click on it and you will see Real Statistics on the left drop down bar.
    A lot of thanks to God and the developer of XRealStats.

  19. If you are having trouble installing, follow these steps: Open Excel > File > Options > Trust Center > Trust Center Settings > Trust Locations. Double-click “Excel default location: Add-ins” and copy the path. The path will be something like “C:\Program Files\Microsoft Office\root\Office16\Library”. After that, open any folder and paste the path you just copied. Move the downloaded file “XRealStats” to this location; you must have admin privileges. Once you have done that, you will be able to install properly by following the guide provided on this site.

  20. Hello,
    I’m trying to do the Kruskal Wallis test and Dunn’s test but he tells me NO RESPONSE. With all the other statistical tests I have no problems, only in the section of ANOVA tests. What I can do? Thank you

    • Hello Itzi,
      Are am not aware of any “NO RESPONSE” message. What is the exact phrasing of the message?
      If you email me an Excel spreadsheet with your data, I will try to figure out why you are getting an error message.

  21. Hello
    When I click on any function in Add-ins tab I get a Excel Security Notice with warning that Microsoft office has identified a potential security concern that says that automatic update of links has been disabled. Than I select to enable trust of source of this file, but after I enable it I get a second warning that says:

    The file could not be accessed. Try one of the following:
    Make sure the specific folder exists
    Make sure the folder that contains the file s not read-only
    Make sure the file name does not contain any of the following characters: ? [ ] : XLSTAT.xls or *
    Make sure the file /path name doesn’t contain more than 218 characters.

    I unblocked XRealStats file file and make sure that folders containing XRealStats file is not read only.
    Could you please help me to solve this issue.

    Thanks and best regards

    • Hello Bernard,
      Generally, after you unblock the Xrealstats.xlam file, everything should work.
      If not, then I suggest that you close Excel and try again. It might be necessary to restart your computer.
      I see that you might be using XLSTAT. I don’t know how this might interfere with Real Statistics.

    • Hello Yuli,
      You should not open the Excel file containing the software. Instead, you should follow the installation instructions on this webpage.
      If you are trying to open an examples worksheet and getting a Protective view then you just need to click on the this message to unprotect the file.

  23. HI Charles,
    I love your stats package. However, I just got a new computer, running EXCEL 365. I followed the installation instructions and got RealStats to load as an addin. However, the moment I close the XL sheet, it disappears, and even though when I reopen XL, it shows that it is loading the macro addin, it fails to appear in the Addins tab. I did try to also load the QAT option, but that would always open an extra spreadsheet every time I clicked it (annoying) so I removed that. I wonder if there is a conflict between the QAT and the regular addin? Any advice?

    • Hello Mark,
      I am running Excel 365 with QAT activated and am not seeing this problem.
      What do you see when you enter =VER() in any cell?
      Can you access the main menu when you press the key sequence Ctrl-m ?

      • Hi Charles,
        Sorry for the delay. Here is what I see:
        8.7 Excel 2010/2013/2016/2019/2021/365 Windows

        Yes, I do see the main menu when I press Ctrl-M. Maybe I will have to resort to that (assuming I remember it!!!).

        It just doesn’t show up in the Addins ribbon.

        Reply

        • Hi Mark,
          You are using the latest release. RealStats should remain on the AddIns ribbon (and QAT) after it has been installed once. I don’t know why this is not happening. Are you using other (non-Microsoft) addins that might be causing conflicts?
          Charles

          Reply

          • I do have another add-in, but it has not caused conflicts in the past (both were present and visible in the ribbon prior to my laptop upgrade). I was on Excel 365 at that time too. I will see if I can figure out what is going on and let you know.

          • HI Charles,
            We figured it out (I think). I had the options (general) set to open with a start screen, rather than a new XL sheet. When I unchecked that option from the General Options (“Show the Start screen when this application starts”, at the very bottom of the general options), it retained it in the Add-ins bar. So, it seems that there’s a conflict between the add-in and the start screen (where you get to choose which spreadsheet you would like to open). Hope that helps. Not sure if there’s a way to resolve it within the add-in coding.

  24. I’ve been trying for hours to download the software but always get the trusted and macro problems. I’ve changed info on the trusted center, enabled macros without notification, gone to internet options and put the site as a trusted site and still end up getting that macro issue. Can anyone help.

  25. Dear Charles,
    If i have observations of a random variable X lets say they are insurance claims. I know them to be lognormally distributed.
    If I calculate the sample mean and variance must I transform them using

    mean = ln(mu) – 0.5 * ((ln(sigma^2)+1) and similarly for the std dev

    or can I use the sample mean and variance directly in Excel Lognorm formulae, directly, without transformation?
