Standard error via v-function

[maumohr]

Dear all,

I ran into an issue when I tried to calculate the standard error of the mean via the v-function.
Somehow, it is not returning the correct result, which it does if I use the Descriptive Statistics tool.
The VSTDEV in contrast seems to work just fine.

I have attached two images of the analysis.

In the first image, I am showing how I set up the VSE function for the variable 's', grouped by 'grade'. You can see that the v-function returns a value of 0.371 for the category '1st-grade'. The right bottom image shows the correct output of the Descriptive Statistics tool, which returns a value of 0.0389.

In the other image, I am showing how I set up the VSTDEV function for the variable 's', grouped by 'grade'. For this variable, the v-function and Descriptive Statistics tool agree.

I would appreciate to hear if I am doing something wrong or if the VSE function does not work properly.
Should these two calculations not lead to the same result?

Thank you very much.

hey maurice,

you're quite right, there's a bug here. we'll push out a new version (hopefully in the next 24 hours) which fixes this.

with thanks
