Which inferential statistical analysis would be used if the Independent Variable (IV) was police force size (measured as the number of officers per 1,000 residents) and the Dependent Variable (DV) was crime rates (measured as the number of crimes per 10,000 residents)?
- Chi-square
- T test
- ANOVA Correlation
Given Information
Chi-square test
The Chi-square test would not be used as the variables are quantitative and do not have any categories.
T-test
The T-test is used in case of a comparison of the mean of two variables. Since the data is missing and it is not specified to test for mean value, the t-test would not be used.
ANOVA
ANOVA is a test for the comparison of multiple mean values of different groups. Since the data is missing and it is not specified to test for mean value, the ANOVA would not be used.
Correlation
Correlation is used to test for the linear relationship between two variables. Pearson correlation test can be used to test the linear relationship between two variables, quantitative.
