Two-sample comparison of proportions power calculation

Post by jacob »

Hi!

How can I conduct a two-sample comparison of proportions power calculation using Jamovi?

In R I would use a power.prop.test function like

power.prop.test(p1=0.1, p2=0.11, power=0.8, alternative='two.sided', sig.level=0.05)

to find the number of observations for each variation.

Thanks in advance!

Hi, @jacob.
In jamovi you can simply use the Rj Editor module and pass it your script to get what you can see in the attached screenshot.
