Questions 1-4

The following data are based on numbers taken from the Bureau of Labor Statistics surveys from the years 2009–2013, with some modifications. They represent the average weekly pay for wage and salary earners measured at 4 different quarters each year and broken down by gender.

· Enter these data into a new file containing one variable for gender and one variable for salary.

· For the gender variable in column 1, code women as 1 and men as 2

o Remember to define these in Value Labels.

o There will be twenty “1”s and twenty “2”s (as many participants as in each group).

· The corresponding scores will be entered in the salary column (second column).

· If you need an example, look at the set-up of gender in the “Lesson 21 Practice Data File 1” document.

Women

646 651 649 672 657 663 672 665 679 669

683 689 673 686 680 697 689 685 685 691

Men

· The BDI (Beck et al., 1961) is an instrument widely used to assess levels of depression in individuals in a variety of settings.

· The scores range from 0–63 (whole numbers only).

· A researcher administers the BDI to a sample of college students. The results appear in the table below.

· They are entered as 2 columns to save space (i.e., you will not need 2 columns in the SPSS file).
