See how in the blog post Save Statistics In Macro Variables.įinally, you can download the entire code from this post here. When you have calculated descriptive statistics, it is often convenient to save them for later use. The MEANS procedure provides data summarization tools to compute descriptive statistics for variables across all observations and within groups of observations. The obvious alternatives are PROC UNIVARIATE, PROC SUMMARY, and PROC FREQ. Consequently, there are dozens of other options and procedures available. However it depends largely on the problem at hand. My usual go-to procedure for descriptive statistics is PROC MEANS. You can find the mean of an entire column by specifying the MIN option with PROC MEANS.

#PROC MEANS SAS HOW TO#

This post demonstrated how to generate simple descriptive statistical sizes in SAS. PROC MEANS is one of the most common SAS procedure used for analyzing data. In SAS, PROC MEANS is a procedure which allows you to create summaries of your data and allows you to calculate things like the average, mean, average, average, etc.

Read all var /* Read variable Height into vector */ close sashelp.class /* Close dataset */ mu0 = 60 /* Hypothesised mean */ N = nrow(Height) /* Number of observations */ min = min(Height) /* Minimum Value */ max = max(Height) /* Maximum Value */ range = max - min /* The difference between min and max */ Mean = 1/n * sum(Height) /* Population mean value */ Std = sqrt(1/(n-1) * sum((Height - Mean)#2)) /* Standard Deviation */ Std_Err = Std / sqrt(n) /* Standard error of the mean */ t_stat = (Mean - mu0) / Std_Err /* T statistic */ p_value = (1-cdf('t',abs(t_stat),n-1))*2 /* P value associated with t-statistic */ print N max min range Mean Std Std_Err t_stat /* Print selected descriptive statistics */ p_value quit Īs you can see from the printed statistics, the values generated are equal to those of the Means Procedure.
