It is said that a student’s college GPA (grade point index) can be predicted by his/her HOCS (higher- order cognitive skills) such as problem identification, analytical reasoning, and content integration skills. What other potential predictor variables, numerical and categorical, would you want to use that might lead to the development of a multiple regression model for predicting a student’s college GPA? Briefly describe the direction of the slope that each of these variables should have.

gpa has a positive relationship with iq. they are both directly related. The more the iq of a a student, the greater is his ability to understand and have a good gpa. the slope will therefore be positive and be in an upward direction.

2. ability to remember

the gpa of students who have a good ability to remember but do not have a good grasp of the subject may not be high. the slope would be in a slightly upward direction

3. study time

gpa and practice have a positive relationship. the more a student studies, the more likelihood exists of having a better gpa. the slope would be upward bound.

4. gym practice

gpa and gym practice are not related so the slope would be in a downward direction.

when interpreting the direction of relationship after carrying out such an analysis, it is useful to watch out for the accompanying signs of the variables. if the sign of the beta coefficient is positive then a positive relationship with the dependent variable exists.
