The primary factor that determines the statistical test students should use is the number of independent and dependent variables. True or False When investigating the relationship between two or more quantitative variables, chi-square is the appropriate test.True or False The Pearson correlation coefficient measures the association between two quantitative variables, distinguishing between the independent and dependent variables.True or False Multiple regression is used when there are several dependent variables and one independent quantitative variable.True or False When testing for the...

A researcher is interested in seeing if playing violent video games leads to a change in aggressive attitudes. The researcher recruits an experimental group, who plays a violent video game for 1 hour, and a control group. Both groups complete a measurement instrument that measures their aggressive attitudes on a scale of 0-100. A. What type of study design is this (descriptive, correlational, or experimental)? B. What would be the appropriate statistical analysis to use in that situation (Chi-Square, Pearson...

10. A recent study of higher education measured the pro- portion of college students who work in off-campus jobs for at least 20 hours a week. Four samples, each composed of 200 randomly selected students, were used to represent four types of institutions: large four-year state schools, small four-year state schools, large four-year private schools, and small four-year private schools. In the sample of 200 students from large state schools, 30 had such an off-campus job (15%), as compared to...
