Statistics: T-test: Testing hypotheses – #260

Question: Choose exactly two of the following four scenarios. For each selected part identify a suitable statistical procedure from among those covered in class (e.g. t-test, regression, ANOVA, Spearman Rho, Pearson correlation, etc.). Why did you select this procedure?

a. Ray has collected attitudinal data (using a 1-5 Likert scale) about a group of workers and their feelings towards work. Respondents are asked eight questions (such "I like my coworkers", "I am challenged by my job", etc.) and are given 1 to 5 scales to respond ("Strongly disagree" to "Strongly agree"). Ray wonders which items are highly correlated with each other.

b. Sarah has collected data about attendance at a college graduation. In particular, she believes that the larger the graduating class, the higher the attendance.
