Now let us say we want to know where the source of this variance is coming from (which group(s) is/are the most different from others), so we decide to see if there is a difference in number of IG FOLLOWERS, JUST between Sophomore and Sr. So, test this new hypothesis: there is a difference in number of IG FOLLOWERS between Sophomore and Sr. What is the correct statistical test (specifically in Excel) that you should use to measure this hypothesis and is it 1 tail or 2 tail?

The accompanying data table lists measures of self-esteem from a student project. The objective of the project was to study how levels of self-esteem in subjects relate to their perceptions of self-esteem in other target people who were described in writing. The test here works well even though the data are at the ordinal level of measurement. Use a 0.05 significance level and apply the methods of two-way analysis of variance. What is the conclusion? Click on the icon to view the data table. F = 5.48 (Round to two decimal places as needed.) What is the corresponding P-value of the test statistic, F, for this test? P-value = 0.006 (Round to three decimal places as needed.) State the conclusion of this test. Reject Ho. There is sufficient evidence to warrant rejection of the claim that measurems of self-esteem are not affected by an interaction between the subject's self-esteem and the target's self- esteem. There does appear to be an effect from an interaction between the self-esteem of…

What does less replicates mean in the context of understanding variance of data?

A sample of 25 freshmen at a major university completed a survey that measured their degree of racial prejudice (the higher the score, the greater the prejudice).  The same 25 students completed the same survey during their senior year. Compute measures of central tendency (mean, and median ) please explain the result? 10 45 35 27 50 35 10 50 40 30 40 10 10 37 10 40 15 30 20 43 23 25 30 40 10
