Question

A two-factor study with 3 levels of factor A and 3 levels of factor B uses a separate sample of 10 participants in each treatment condition. How many participants are needed for the entire study

Answer 1

`P=60`

Explanation:

From the question we are told that:

Number of Factor study
`N=2`

Level
`L=3`

Sample size
`n=10`

Generally the umber of participants needed for the study is mathematically given as

`P=N*L*n`

`P=2*3*10`

`P=60`
