Question

In a paired-samples study, you collect pre-treatment scores and post-treatment scores from 5 people. You get the following dataset: Score Score Difference at at score time 1 time 2 $x_1$ $x_2$ $x_1 - x_2$ person 11 9 2 1 person 10 7 3 2 person 9 4 5 3 person 6 4 2 4 person 5 2 3 5 $\bar{x}_{diff} = 3$ $sd_{diff} = 1.22$ Use numerical values (and NOT letters or subscripts) and write the linear equation for sampling error variance in a population assuming $H_0$ is true.

In a paired-samples study, you collect pre-treatment scores and post-treatment scores from 5 people. You get the following dataset: (ar{x}_{diff} = 3, ext{sd}_{diff} = 1.22) Use numerical values (and NOT letters or subscripts) and write the linear equation for sampling error variance in a population assuming Ho is true. In a paired-samples study, you collect pre-treatment scores and post-treatment scores from 5 people. You get the following dataset: Score at time 1 | Score at time 2 | Score Difference (X1 - X2) person 1 | 9 | 2 person 2 | 10 | 7 person 3 | 9 | 4 person 4 | 4 | 2 person 5 | 2 | 3 (ar{x}_{diff} = 3) ( ext{sd}_{diff} = 1.22) Variance in a population assuming Ho is true
