What statement is used to create a histogram in SAS?

The statement used to create a histogram in SAS is provided through the PROC SGPLOT procedure with the HISTOGRAM statement. This is an efficient and straightforward way to produce a histogram, allowing for quick visualization of data distributions.

The PROC SGPLOT procedure is versatile, enabling users to create various types of graphs easily. Within this procedure, the HISTOGRAM statement specifically instructs SAS to produce a histogram for a specified variable. This process involves grouping the data into bins and displaying the frequency of occurrences for each bin, which is essential for understanding the distribution of continuous variables.

The other choices do not accurately represent the current methods in SAS for creating histograms. For instance, while PROC CHART may be used for certain types of data visualizations, it does not specifically provide a histogram feature. Similarly, the DATA step with GRAPH options and PROC HISTOGRAM are either outdated or not directly associated with the histogram creation in the way that PROC SGPLOT with the HISTOGRAM statement is utilized in modern SAS programming.

In summary, the use of PROC SGPLOT with the HISTOGRAM statement is the current, preferred method for generating histograms in SAS, making it an essential tool for data analysts.
