/* The following procedure produces several summary statistics and graphs */

/* DATA= tells SAS which data set to use */
/* VAR tells SAS which variable to compute the statistics and graphs for */

/* If there are several variables in the data set */
/* you could specify more than one variable with VAR */


PROC UNIVARIATE DATA=raindata PLOT FREQ TRIM=0.10 0.20;

VAR rainfall;

TITLE 'Summary of the Rainfall Data for the 70 Cities';

RUN;

/* PROC UNIVARIATE gives summary statistics about the variable "mileage" */
/* Look for the mean, median, variance, standard deviation, etc. */

/* The PLOT FREQ command produces a stem-and-leaf display and boxplot */
/* Notice the UNIVARIATE procedure produces rather rudimentary graphs */

/* The TRIM= option gives (in this case) the 10% trimmed mean and the 20% trimmed mean. */

/* The INSIGHT procedure will give us the same thing as UNIVARIATE */
/* but with more and nicer-looking graphs. */

/* The syntax is slightly different in INSIGHT: */

PROC INSIGHT;

OPEN raindata;

DIST rainfall;

RUN;

/* The graphs INSIGHT produces are a box plot and a histogram.*/

/* To change the class intervals, */
/* click on the arrow at the bottom left of the histogram. Choose "Ticks". */
/* First Tick is the start of the first interval, */
/* Last Tick is the end of the last interval, */
/* and Tick Increment is the interval width.  */

/* Note how changing the class intervals changes the look of the histogram. */

/* Note that the histogram shown is a relative frequency histogram. */
/* To get a frequency histogram, while still in PROC INSIGHT, */
/* choose the "Analyze" menu, and choose "Histogram/Bar Chart". */
/* Click on the name of the variable (here, MILEAGE) and then click "Y". */
/* Click "OK" and a frequency histogram should appear. */

/* To get a trimmed mean from PROC INSIGHT, choose the "Tables" menu, and then */
/* choose "Trimmed/Winsorized Mean", and then "(1/2)Percent".  In the box that */
/* pops up, choose "Other" and type, say, 10 in "Value" for the 10% trimmed mean. */

/* You can copy and paste the graphs from PROC INSIGHT into Microsoft Word */
/* Click on the border of the box you want, and copy and paste as normal */

/* To quit PROC INSIGHT or remove the INSIGHT graphs, */
/* click the X in the upper right box of the graph(s) */
