Elementary Statistical Calculations on Internal Data

This program initializes a SAS^© table named 'dummy' with numeric values entered via the CARDS statement. It then performs a series of statistical calculations (maximum, minimum, sum, median, mean, square root) on these variables within a DATA step, before printing the results.

Data Analysis

Type : CREATION_INTERNE

Data is generated directly in the code using the 'cards' statement.

1 Code Block

DATA STEP Data

Explanation :
Creation of the 'dummy' table. The 'input' statement reads 5 variables. Raw data is provided line by line, and SAS continues reading on subsequent lines to complete an observation.

1	DATA dummy;
2	INPUT X1 X2 X3 X4 X5;
3	CARDS;
4	21
5	42
6	13
7	10
8	29
9	;
10	RUN;

2 Code Block

DATA STEP Data

Explanation :
Transformation step: reading the 'dummy' table and creating new variables containing descriptive statistics (Max, Min, Sum, Median, Mean, Square root) calculated horizontally across variables X1 to X5.

1	DATA dummy;
2	SET dummy;
3	max = max(X1,X2,X3,X4,X5);
4	min = min(X1,X2,X3,X4,X5);
5	sum = sum(X1,X2,X3,X4,X5);
6	median = median(X1,X2,X3,X4,X5);
7	mean = mean(X1,X2,X3,X4,X5);
8	sqrt = sqrt(sum(X1,X2,X3,X4,X5));
9	RUN;

3 Code Block

PROC PRINT

Explanation :
Displaying the resulting 'dummy' dataset in standard output.

1	PROC PRINT DATA= dummy;
2	RUN;
