Histograms (Graphing)

Using the nlsw88 data,

1. Draw a histogram of hours worked per week, with the percent of workers on the y-axis.

2. Draw a histogram of hours with 10 bins.

3. Draw a histogram of hours controlling the bin width directly starting the first bin at 0 and having bins of width 5.

The variable grade records completed years of education and takes on integer values, meaning it is a discrete variable. In this case, Stata will make better looking historgrams if you tell Stata that the variable is discrete.

Start by graphing grade using just the hist command.

4. Draw a histogram of grade using the discrete option along with frequency.
