    I have downloaded the resource pack, but it won’t let me add it in as an add-in. It keeps saying RealStats.xlam is not a valid add-in. Any ideas? I am running Office 2003 so perhaps that is the problem?

    • Charles says:

      The Real Statistics Resource Pack add-in should operate correctly with Excel 2007, 2010 and 2013. I have not tested it with Excel versions before Excel 2007. In particular the file extension of the add-in that is supplied is .xlam. The file extension for Excel 2003 add-ins is .xla. In the next couple of days I will try to to save the Real Statistics Resource Pack add-in in the older .xla format. If so I will put this version on the website for downloading. I would appreciate it if you would then tell me if this version works on your computer.

      Update (29 Aug 2013). You can now download the Excel 97/2003 version of the Real Statistics Resource Pack from webpage Please let me know whether it works on your computer.

      • Robert de Kock says:

        This looks like a very good thing for me who still runs Excel 2003. I would like to try this out, but where on the page is the link to the .XLA file?

        • Charles says:

          I am trying to get an .XLA version running now. I hope to have this available later this week.

        • Charles says:

          I added the .XLA version of the software earlier this month. Have you been able to download it? Is it working properly?

  2. John MacGaffick says:

    Charles, I downloaded the package, but when I went to customize my ribbon, I could not find the macro.

    • Charles says:

      Unfortunately this is a common problem. I don’t have a solution yet. For now simply press Ctrl-m to access the Real Statistics data analysis tools. This works fine.

  3. Steve says:

    Hi Charles,
    This is a wonderful add-on and am enjoying using it for teaching postgrads online . Have a window that keeps asking for a password though. Can’t seem to get rid of it…

    • Charles says:

      Hi Steve,

      Pleased to read that you are using the software to teach postgraduate students.

      I don’t know why you would receive a window requesting the password. The only reason I can think of for this happening is if you try to open the add-in. In that case you would certainly receive a request for the password. As you have seen you can use the software without needing a password.

      In any case it is not great to keep being badgered for a password. Perhaps I can figure out how to get rid of the request. Which version of Excel are you using? Can you send me a screen capture of the window that asks for the password (using the PrntSrn key or Window’s Snipping Tool)?

    Dear Charles:

    I downloaded the last version of the Pack, ver 2.6, but the Ver() function output is still 2.5. Any comments?

    Best regards,


  5. Jianguo Chen says:

    Hi Charles,
    I downloaded the last version of the Pack, but when I loaded it into Excel 2013, and used it via Ctrl+M, I met with a popup window that keeps asking for a password too.


    • Charles says:

      Hi Jianguo,

      It is not sufficient to download the software. You also need to install the software. You do not need a password to do this. Please follow the following steps:

      To install the software select Office Button > Excel Options > Add-Ins in Excel 2007 or File > Help|Options > Add-Ins in Excel 2010/2013, it is important that you look for the Go button at the bottom of the window. You need to click on this button.

      Once you do this you should be presented with a dialog box as described in the instructions. If you have already put the Real Statistics Resource Pack file in the appropriate add-in directory you should see its name on the list shown, in which case you need to make sure that the file is checked. If not, you will need to search for it by pressing the Browse button on the dialog box.

      Please let me know if this doesn’t work for you.


  6. Jianguo Chen says:

    Hi Charles,
    I have downloaded and installed the software follwing the steps as you told me, and I can open the function window via Ctrl+M to analysis my data. But, when I close the function window, a popup window that keeps asking for a password still appeared in the screen, and I can only close it after clicking the mouse twenty times. I don’t know why.

  9. Chanchal Kumar says:

    Hi Charles,

    It seems you had created a wonderful add-in application, unfortunately I am not able to use it.
    I had installed the add-in as per instruction in my Excel 2013, but not able to see the Realstata add-in in the ADD-IN ribbon. So my question is where to find the Realstats add-in after installation to use it?

    Please suggest.


    • Charles says:

      Once the Add-in dialog box is displayed (e.g. by pressing Alt-TI) if realstats is not displayed, click on the Browse button and select the file containing the software that you downloaded from the website. You should now see realstats on the Add-in dialog box. Check the box to the left of realstats and you should be in business. Let me know if this works.

  20. Jakob says:

    Currently working on my BA, first time doing empirical research and it’s a real help using your website. However, I downloaded your Real Statistics Resource Pack but keep running into error messages. I installed it and can open the console via Strg + m. However, if I try to actually active the formulas (e.g. the correlation matrix) I always receive an error saying (roughly, it’s in German):

    2Compiler error in the module: frmMatrix
    This error generally occurs if code is not compatible with the used version, platform or architecture.”

    I’m using Office 365 Home, if that matters. Any idea what might be the issue?

    • Charles says:

      I don’t know what is causing this problem. I know that some other people have experienced similiar problems, but the software seems to run fine for most people.
      Do use see the version number when you enter =VER() in any cell in a worksheet? (if not the installation was not performed correctly) Are you by any chance running the 64 bit version of Excel? (select File > Help to find out) Are you able to get the software working on some other computer?

      • Jakob says:

        The =VER() command works, showing me Version 3.5.2. I’m using the 32bit Excel, so that can’t be it. I don’t have another machine available currently to test your last question.

        • Jakob says:

          Sorry, there’s no option to edit a post: I’m also being asked (sometimes) to enter a password and if I activate/deactivate the AddIn I receive an error message saying something like:

          Microsoft Visual Basic for Applications
          “Project or library not found.”

          • Charles says:

            You should never need to enter a password. Since the formula =VER() works properly I am very surprised to see that you are getting a message to enter a password.
            I have just put a new version of the software online (Release 3.6). I suggest that you delete the software from your computer and install the latest version. Let’s see whether this eliminates the problem.

    Hi. I downloaded the version and the installation went fine but my excel is in portuguese, so it appears a compilation error for me. Now, I cant even uninstall the .xlam supplement. How do I uninstall it? And how can I get a portuguese version? (assuming that the error is because of the language)

    • Charles says:

      The version that you downloaded has worked in German, Italian, Spanish and several other languages. There appears to be a large user population in Brazil, and so it probably also supports Portuguese.
      Uninstall is similar to Install. Assuming that you are using Windows, press Alt-TI and unclick RealStats from the dialog box that appears and press the Close button. That’s all you need to do.

    I tried to install and use the addins package but it failed. I accidentally click the downloaded file when my Ms Excell was active. A dialog box asking me something about macros and i got suspicious and refer to your installation guidance once again. I then simply closed the dialog box and follow your installation guide.

    2. During using chi-square test, “Compile error in hidden module: ChiSquare”

    • Charles says:


      In order to figure out what is going wrong I have the following questions:

      1. When someone is asked to give a password, this usually means that they are trying to open the RealStats-2007 file. You should never need to supply the password. Since you are getting the correct value for =VER(), this usually means that you were able to install the software properly (as described on the Download webpage. Is this what you did?

      2. Are you able to use any of the Real Statistics data analysis tools? E.g. the Descriptive Statistics and Normality data analysis tool. Does the version of Office 2007 also include Outlook and Access?

    Charles, thank you very much for the add-in.
    How do you calculate the Probability Density Function (pdf) ?
    I understand formula normsdist(z,false) is the one to use; however, in Excel 2007 that does not work – it works without the FALSE argument. If I enter FALSE, or TRUE, I get an error message as the formula is not set up to accept the TRUE or FALSE.

    Is it possible to calculate the pdf using your add-in ?

    • Charles says:


      You can use =NORMDIST(x,0,1,FALSE) in Excel 2007.

      Excel 2007 also doesn’t provide the pdf for the t distribution. In this case you can use the Real Statistics function T_DIST(x,df,FALSE).

    • Charles says:


      If you are using Excel 2007, a likely reason for this is that you need to install the latest service pack, namely SP3.

      Otherwise, it is possible that you need to install Excel’s Solver, as described in the next paragraph.

      The latest version of the software uses Excel’s Solver, and so you need to make sure that Excel’s Solver is installed. You do this by pressing Alt-TI (i.e. hold down the Alt key and press T and I) and making sure that there is a check mark next to Solver in the dialog box that appears. Then close Excel and reopen Excel.

      The software will run on Windows 7, 8 and 10 (and probably XP as well). It supports Excel 2007, 2010, 2013 and 2016.
      The software will also run on Mac OS, supporting Excel 2011 and 2016 (I don’t believe there is an Excel 2013 version for the Mac, but if there is then the software should support that as well). The Windows version of the software has more capabilities than the Mac version.

    Hai Dr. Charles;
    I hope you are well.
    I sure you would help me, where I have a statistical problem as follow:
    I have 2 populations, 1st is a health providers at 2 hospitals (supervisory staff) with total sample size of (328 person) and the 2nd population is the in-patient at the same 2 hospitals with total sample size of (540 pts.). 2 surveys was used to collect the data, one survey for each population, the 1st one (with 68 questions) for the 1st population used to measure the level of using Six Sigma Methodology (DMAIC) at 2 hospitals, and 2nd one (with 36 questions) for the 2nd population that used to measure the level of patient’s satisfaction under light of using Six Sigma Methodology (DMAIC) at the same 2 hospitals. Both surveys has the same 5 dimensions (DMAIC) with same Likert Scale (5 scale), the data was collected at the same times. There are difference in questions no. between the 2 surveys, but there are (13) similar questions in every survey.
    N.B: The surveyed (male and female) pts are from several ward (medical, surgery and obstetric wards), also most of health provider (male and female) are from these wards. 
    I need to find the effect or association (correlation) between the level of using Six Sigma Methodology (DMAIC) as (X variable) and the level of patient’s satisfaction under light of using Six Sigma Methodology (DMAIC) as (Y variable) using the data that collected as mentioned above. So I do the following:
    1. Assuming that, level of pt. satisfaction is the Y variable, so I fixed every pt.’s case score (average mean for every dimension and total mean score), then we have 540 pts. with (6 scores for every one).
    2. Also I assuming that, level of Using Six Sigma Methodology (DMAIC) is the X variable, then I measure the score for every health provider case (total of 328 person), so I have 6 scores for every one (average mean for every 5 dimensions and total mean score).
    3. Using bootstrapping technique to generate random samples form the scores of health provider cases that every random sample contain (10) cases of them together which starting with a certain generated no. and calculate the scores, then return back the cases for the origin samples.
    4. Repeat previous step (3) starting with a new generated no. to be sure not repeat the same generated random sample.
    5. With step (3) and (4), using bootstrap, so we have (1000) random samples for each (540) pt. cases.
    6. From the previous steps we will calculate the correlation between (X) and (Y).
    My question is that: Is this procedure right to calculate the association between X and Y?, if Yes, which test can I used to perform it?, if No, How to do this right?.
    Or I must measure the overall level of using Six Sigma Methodology as will as the pt.’s satisfaction in each ward of hospital alone then match them and do the bootstrap, or do it by gender in every ward then match them as:
    Overall score of female (Health provider) in surgery ward (X variable), attach with overall score of female (inpatients) in surgery ward (Y variable).
    And overall score of male (Health provider) in surgery ward (X variable), attach with overall score of male (inpatients) in surgery ward (Y variable).
    Also the medical and other ward the same as previous.
    I’m looking for your kind answer.
    best regards;

      It looks like you have a very important research to undertake and your approach may be a good one to follow. I am happy to answer specific questions (with a limited number of complications), but I don’t have the time necessary to really understand the details of the scenario that you are describing.

    Dear Dr Zaiontz:

    One of my students updated windows 10 using Fall Creators Update. Apparently there is a compatibility issue with the last version of Real Statistics. Do you have any info on this?

    Thanks in advance for your help


    • Charles says:

      Hello Jorge,
      Thanks for the heads-up. So far I haven’t heard of any compatibility issues specifically related to the Fall Creators Update, but various issues have been appearing over the course of the last few months which may be related. I have just added a Troubleshooting section on the webpages from where people download the Real Statistics software that explains how to deal with these issues. I will make the required changes as I learn more.

    Hello Sir,
    Thank you for your site, very useful.
    I’m also encountering compatibility issues. I’m running in Windows 10 (64bit) and have recently updated to the Fall Creators Update. It’s my first time to try your real stat add-in though, so I have no comparison with the other versions of Windows 10. I’m using Excel 2016.

    I was able to install the add-in just fine. Solver add-in is also installed. But when I try to use any of your functions, KCORREL for example an error appears:

    “Compile error in hidden module: Correlation.
    This error commonly occurs when code is incompatible with the version, platform, or architecture of this application.”

    With the add-in installed, I encounter “Automation Error” pop-up everytime I open the Excel.
    I also did the troubleshooting instructions mentioned but didn’t work.

    Thank you!

    • Charles says:

      Do you also get this error message when you enter the following formula? =VER()
      It sounds like you have done all the right things, but I don’t have any experience with the Fall Creators Update to know whether it is causing the problem.

      • Apple Gupin says:

        Hi Charles,

        I found out that it’s the solver add-in that’s causing the error. I’ve seen many people raised that issue over the internet but has yet to be resolved. Anyway I was able to run your add-in on a different machine.

        However, I was getting the KCORREL for 2 columns (18,000 rows). It was able to compute for the kcorrel, but when I invert the order of the columns, say KCORREL(B,A) instead of KCORREL(A,B), I get #VALUE as the result. Shouldn’t it be somewhat commutative, I mean not order-specific? So I am expecting the same result when I do KCORREL(A,B) and KCORREL(B,A).

        Thanks a lot!

        • Charles says:

          1. When you say that Solver is causing the error, do you mean that Solver was not installed (and checked in the list of addins)?
          2. Yes, KCORREL(A,B) and KCORREL(B,A) should yield the same result. If you send me an Excel file with your data, I will try to figure out what is going wrong.

    Dear sir,

    I downloaded year new updated RealStats.xlam software for 2013/2016. I installed in my computer. But this software has to be installed time and again for every file. RealStats.xlam works for only one time. Why??
    Your old version software did not give me this type of trouble. Please, tell me any solution for new updated RealStats.xlam software for 2013/2016.

    • Charles says:

      Please explain what you mean by “this software has to be installed time and again for every file.” What do you mean by “every file” since there is only one file realstats.xlam? Also what do you mean by having to install “time and again”? Are you saying that when you close Excel and then reopen it, =VER() and Ctrl-m no longer work? If so, this is strange.
