Question

Two students analyzed the same data from a study. Student 1 used a one-sided test and Student 2 used a two-sided test. The p-value of the test corresponding to Student 1's analysis was found to be 0.042. What is the p-value for the test performed by Student 2?

Answer 1

`p value = 0.084`

Explanation:

Given that one of two students analysed the data by using one sided test and got p value as 0.042

Second student analysed the same data by using two tailed test and got p value

We have to find the second p value

p value one tailed = 1/2 ( p value of two tailed value)

Hence

the p-value for the test performed by Student 2=2(0.042) = 0.084
