\f21- 213 214 EY1 = EYE = EY3 = EY4 = 1. Check the assumptions against the details of the research scenario (+2 points) 2. State Hi, Ho, and alpha (+ 1 point) 3. Select the sampling distribution and specify the test statistic (+2 points) 4. Compute the test statistic; compare to critical statistic: a. Compute the mean for each group (+5 points)b. Compute the variance and standard deviation for each group (+5 points) E( Y - P)2 E( Y - P)2 n - 1 SD = n -1 c. Compute the overall mean (+2 points) d. Compute the between-group sum of squares (SSB) (+7 points) *The SSB measures the difference in average number of facts recalled between all groups. **SSB is also referred to as explained variance. SSB - Enk(Yk - )? nx is the number of cases in a group (k represents the number of different groups) Yx is the mean of a group Y is the overall mean e. Compute the within-group sum of squares (SSW) (+7 points) *The SSW measures the difference in average number of facts recalled within one group. **SSW is also referred to as unexplained variance. SSW = EY- - E- nkf. Compute the total sum of squares (SST) (+2 points) *The SST combines the SSB and SSW together to represent the total amount of variance in average number of facts recalled for the entire sample. SST = SSB + SSW g. Compute the degrees of freedom for the SSB and SSW (+4 points) dfo = k- 1 dfu = N -k h. Compute the mean square between and the mean square within (+4 points) SSB Mean square between -af; SSW Mean square within - afwCOMM 2513 Name: i. Compute F (+2 points) Mean square between F = Mean square within j. Using dfo and afw, locate the critical F value in the F distribution and write it below (+2 points) 5. Interpret the results and make a decision regarding Ho (+5 points)Step by Step Solution
