Using t-Test for Dependent or Correlated Samples, follow the steps below. All given are on the picture:

Testing the significance of the difference between means 5. Computation when the samples are dependent or correlated a. Create a table Individuals Condition 1 Condition 2 D, D2 1. Ho: My = H2 , That the mean of population 1 is equal to the mean of Mean Difference population 2 The alternative hypothesis may be defined in one of the three hypothesis presented below: Total a. HA: H1 > H2, That the mean of population 1 is greater than the mean b. Solve for the difference in each column D, and square of the difference D,? of population 2 C. Solve for the mean difference d. Solve for the variance of the mean difference . Do mean of difference b. HA: H1
