Please help me answer these questions for this scenario:
Scenario 1
A researcher investigates whether muscle relaxation training is more effective than drug therapy in reducing hyperactivity. Children with hyperactivity are assigned to the muscle relaxation group or the drug therapy group. The number of behaviors indicative of hyperactivity is recorded after each treatment. During the experiment, the research notice that two of the children are extremely hyperactive compared to the others (e.g., outliers). The researcher wants to know which program was most effective in reducing hyperactivity.
- Whether the test is measuring a relationship between two variables, or comparing measures of central tendency for one variable.
- if comparing measures of central tendency, is it a between or within subjects design?
- What scale is the data measured on (nominal, ordinal, interval, or ratio)?
- What is the appropriate test for analyzing the data?
- (Chi-square goodness of fit, Chi-square test of independence, Pearson r, Spearman's rho, Independent groups t-test, Dependent groups t-test, Mann-Whitney U test, or Wilcoxon test)
Scenario 2
A researcher is interested in the effects of hair color on perceived age. Participants are shown a set of photographs of women. The set contains three photos. All of the women pictured are the same age. One of the women in the set has blond hair, another has brown hair, and a third has black hair. Participants are asked to identify the woman who appears the youngest of the three categories, and researchers will evaluate which of the three categories gets more votes.
