//  Task 2: Keep four variables including cit9, fel, female and mcit3.
//  Examine thesr variables, drop missing cases, and draw scatter plots.

//  Step 2.1 keep the variables cit9, fel, female and mcit3.

//  Step 2.2 examine variables

//  Step 2.3 drop missing cases.

//  Step 2.4 graph matrix to explore your variables.


//  Task 3: Estimate an OLS regression and list coefficients.

//  Step 3.1 run a regression of cit9 on fel, female and mcit3.

//  Step 3.2 list the standardized coefficients


//  Task 4: Interpret the standardized and unstandardized coefficients.
