I am not familiar with the WHO STEPS instrument, and so I would need more information about it before I could help you. Is the problem that you are having the fact that (1) there is a mixture of question types and/or (2) there is no scoring system for the open-ended questions? Or is there some other issue?

Thank you very much for your kind remarks. I have tried my best to create explanations that are easy to follow and tools that are easy to use and easy to understand.
Please feel free to tell you students about the website so that they too can learn from the site and download the software from the site.

Does this problem occur when you use one specific data analysis tool or does it occur for multiple data analysis tools? Which tools have you trued? What is the result, when you enter the formula =VER() in any cell?

With a chi-square test for independence, you are trying to determine whether two variables are independent. For your problem, what are the two variables?

It is very likely that the FDIST (or F.DIST.RT) formula that is calculating the p-value has an overflow problem. If you send me an Excel file with your data and analysis, I will try to figure out what is happening. You can find my email address at Contact Us.

You can draw an regression fit line at least for the case with only one x variable by using the Trendline option of a Scatter chart. If you have more than one x variable or are employing Anova using Regression, then the regression fit line is not a line but a hyperplane and it won’t be easy to draw.

Your discussions are marvels of clarity, as are the spreadsheets. I’ve taught introductory applied statistics for over 30 years, and have long advocated for using Excel for exactly the reasons you mention. I even developed a small set of tools to share with my beginning students–but nothing as systematic and thorough as what is here. With your permission, I’ll be sharing your website in the future with all of my students and colleagues.

I have a complete ANOVA table and want to draw a regression fit line.
How to do that ?

I need to help in fixing a problem i have in my data. I am running a gravity model – regression for trade analysis between France and selected partner. I have a data panel in excel with dummies and transformed values.
The issue is if I run the regression the out have #num! in the probability column and the somethings the significant value also has this #num!. how to solve this in my this issue. I am very new to econometrics

I adapted the WHO STEPS instrument for identification of risk factors of Non-communicable diseases to identify risk factors of essential hypertension via a retrospective hospital based case control study in my locality. the WHO STEPS instrument only seek to identify previous occurrences and their pattern among cases and controls with a combination of YES and NO questions, MULTIPLE CHOICE questions and OPEN ENDED questions which do no have an actual scoring system. I have also not found any previous psychometric properties of the WHO STEPS instrument. please, how do I validate and establish reliability of the adapted instrument
