Hi
I have a dataset, that looks in a simplified form like this:
Age (in years)___ Number of people (N) for factor 1
0-5____ ________30
6-10___________40
11-15__________28
16-20__________21
...
...
...
91-95_________4
96-100_________2
The dataset contains over 100 columns!
1. Is it possible to group (in larger groups) the already grouped data?
like:
Age
0-20
21-40
41-60
...
2. Is it possible with jamovi to perform "simple" tests (t-test - Chi Square) on the grouped data?
3. I solve the "grouping" issue by calculating the new groups in Excel - I wanted to know if there is in jamovi an automated procedure to summarize the groups.
Thanks
John

Re: Group already grouped data
Hi, John.
Sbalci has already suggested you take a look at some useful links,
but if i understand your requests i think the next tips can help you.
A t-test with data grouped in class (like yours), you can't find it and you could do it with r code in Rj.
A chi-square test of independence is very quick to do in jamovi, organizing the data as in the screenshot example:
The age_class variable (8 classes) is TRANSFORMED into a new variable with only 3 classes.
Ricorda di selezionare prima la variabile da trasformare che sarà identificata con $source. Cheers,
Maurizio

Jamovi does many things, and these have increased with the use of modules that have been added over time and one of these (Rj) is a real wildcard for doing things with R code, which at the moment are not accessible in a simple way directly jamovi.istratos wrote: 2.
