I have to say that our students love jamovi - who though I will ever say this about a statistic program. Really great job!

However, I mentioned this before that the definition of a missing value value is not carried over when computing a new variable or transforming a variable, leading to wrong results. And it looks like, this is not fixed in the latest version. Here the example. I create two new variables (A and B ) with some values and some missing values and define -99 as missing value and then compute a mean score. The missing value is recognized by jamovi for the variables A and B (in gray) but not for the new variable, resulting in including the -99 into the mean value:

A B

1 2 https://omegle.onl/ https://vshare.onl/

2 -99

Using MEAN(A,B) will give:

A B score

1 2 1.5

2 -99 -48.5
