Re: T-test
sounds like you're on the right track ... you'll be wanting to use an "independent samples t-test". one column will contain the measure of interest (your dependent variable) and one column will contain their group (those having used biologic therapies before, and those who haven't). if you...

Re: How are percentiles calculated?
hi,
jamovi uses the quantile function from R, which looks to default to "type 7" quantiles.
you can reproduce with the following R code:
quantile(c(5, 8, 10, 15, 18, 25, 30, 35, 40, 45))
cheers

Re: Computing Mean Score - ignoring certain values without excluding participant/row altogether
so in statistics, we treat a missing value as "don't know" ... so if you take the mean of three values, and one of the values is "don't know", then you "don't know" the mean of those three values either. ignore_missing=1 is where you say to ignore the missing value, so ...

Re: Combine Multiple Non-Mutually Exclusive Variables
Hi, thanks for raising this. so called "multiple response variables" are something of an area of weakness in jamovi at the moment. i've made a couple of changes to jamovi to better support this; i've added an ignore_missing argument to the HLOOKUP() function, and i've added a COUNT() funct...
