Q 6 Which of the following statements are true about mean differences and simple regression? (Check all that apply.)
1 | A simple regression with a binary independent variable will produce an unstandardized regression coefficient that is equal to the difference in means between the two groups. | |
2 | A simple regression with a binary independent variable does not allow you to analyze the actual difference in means between the two groups. | |
3 | A simple regression with a continuous independent variable will produce a standardized regression coefficient that is equal to the Pearson's correlation coefficient for the relationship between the two continuous variables. | |
4 | The p-value on the regression coefficient for a simple regression with a binary independent variable will be equal to the p-value for the independent samples t-test for the difference in means between the two groups. |
