Question

Consider the HSB data set and do the followings:

(c) To predict math scores (MATH) using writing scores (WRTG) as independent variable, perform a regression analysis for males and females separately.

Variable N Mean Std Dev Sum Minimum Maximum
WRTG 273 49.78608 10.17605 13592 25.50000 67.10000
MATH 273 52.34542 9.80706 14290 31.80000 75.50000

Answer 1

To perform a regression analysis to predict math scores using writing scores as an independent variable for males and females separately, calculate the regression equations and apply them to predict math scores.

Step-by-step explanation:

To perform a regression analysis to predict math scores (MATH) using writing scores (WRTG) as an independent variable for males and females separately, follow these steps:

1. Calculate the regression equation for males using the WRTG as the independent variable and MATH as the dependent variable.
2. Calculate the regression equation for females using the same variables.
3. Apply the regression equations derived in steps 1 and 2 to predict the math scores for males and females based on their respective writing scores.

Note: The regression analysis should be performed separately for males and females to account for any gender-specific differences in the relationship between writing scores and math scores.
