Question

1.A researcher wants to investigate the relationship/correlation between reading and writing scores. A researcher gave reading and writing examinations to a group of 20 students who had been selected at random from a large population of undergraduates. It is presumed the data for both variables is normally distributed.

2. A researcher wants to assess the correlation between two variables: 1) stress level of college students during final exams and 2) increased antacid use (measured as a Likert scale). One or both of the variables are not assumed to be normally distributed.

3. A researcher wants to know if watching crime-related TV programs influence the way people feel about criminal's rights. The researcher selects a random sample of people and ask them how many hours of crime-related TV they watch per week, and if they believe that criminals have too many rights (measured on a scale from 1 to 5, with one being "strongly disagree" and 5 being "strongly agree"). The researcher wants to predict the attitude towards criminal rights of someone who watches 6 hours of crime-related TV per week.

From the list shown below, for each of the following hypothesis testing situations indicate the type of test you would use. Unless otherwise, the significance level for all the tests is .05.

One-way ANOVA

Pearson product-moment correlation

Kruskal-Wallis

Spearman rank correlation

Linear Regression

Multiple Linear Regression

Explanation / Answer
