I need to answer the point biserial correlation coefficient and the phi coefficient.

The questions you will answer using SPSS to obtain the point biserial correlation coefficient between gender and age in years [age].

The magnitude(absolute value) of the point biserial correlation coefficient between gender and age is = ???.

Create a new variable "married" whose value is 0 if the person is currently not married and 1 if the person has is currently married. (Hint:Code "separated" as "currently married.")

Use SPSS to obtain the phi coefficient between gender_code and married. The magnitude (absolute value) of the phi coefficient between gender_code and married is ???
