graph box mpg, by(foreign)ДЄs you can see in the graph above, there are a pair of outliers in the box plots produced. The boxplot can be done separately for foreign and domestic cars using the by( )В or over( )В option.

The median is pulled to the low end of the box. If mpgВ were normally distributed, the line (the median) would be in the middle of the box (the 25th and 75th percentiles, Q1 and Q3) and the ends of the whiskers (the upper and lower adjacent values, which are the most extreme values within Q3+1.5(Q3-Q1) and Q1-1.5*(Q3-Q1), respectively) would be equidistant from the box. The graph boxВ command can be used to produce a boxplot which can help you examine the distribution of mpg. If you are creating a histogram for a categorical variable such as rep78, you can add the option discrete.В As you can see below ,В when you specify this option, the midpoint of each bin labels the respective bar. The histogramВ command can be used to make a simple histogram of mpg histogram mpg LetвЂ™s use the autoВ data file for making some graphs.
