For the following experiments, provide the requested information. Provide the IV, DV, and name of the test. Be specific. The test choices are Independent and repeated ANOVA, correlation, and chi-squared. Not all tests are given.  IV = independent variable                  DV = dependent variable   A psychologist is interested in the change in behavior produced by a behavior modification program.

t test for Independent Means  Professor Smith hypothesizes that type of TV show impacts people’s mood. To study this, she uses two groups: the experimental group who watches reality TV shows for three hours, while the control group watches the news for three hours. Each of the groups then completes an assessment of mood. In all, 32 people participate: 17 watch reality TV shows and 15 watch the news. The Mean, Sample Size, and SS for each group are below. Using these data, conduct a t test (p<.05) to determine if TV show type had an impact on an individual’s mood. Reality TV Shows:                News: N = 17                         N = 15 M = 34                       M = 24  SS = 340                      SS = 251   Step 1) Create a research hypothesis and a null hypothesis about the populations. Null hypothesis (H0): Research hypothesis (HA):   Step 2) Determine the characteristics of the comparison distribution. Degrees of freedom for experimental group and control group = df1 =…
