exercise4= Analysis of Variance

exercise6= multivariate

exercise2= d

exercise4= d

exercise6= b

Module19

exercise2 = dependent variable must be quantitative

Independentvariable must be within the subjects

Independentvariable must have two levels

exercise4 = the measure is on interval

exercise6

Pairedsample t-test

Ho=There is no difference in means between difficulty studying materialin music and no music conditions

Ha= There is difference in means between difficulty studying materialin music and no music conditions

PairedT-Test and CI: music, no music

ThePaired T for music – no music

95%CI for the mean difference: (-2.721, -0.136)

T-Testof the mean difference = 0 (vs ≠ 0): T-Value = -2.71 P-Value =0.035

1. Yes. There is a difference in means between difficulty studying material in music and no music conditions

2. because the p – value is less than 0.05 (Jackson, 2014)
