Question

What does PROC TRANSPOSE do by default, without any options or statements?

a) It transposes all variables in the dataset.
b) It reverses the order of the observations.
c) It creates a new dataset with the same structure.
d) It deletes the dataset.

Answer 1

PROC TRANSPOSE by default transposes all variables in a dataset, turning the columns into rows and vice versa, resulting in a new dataset with the transposed structure.

Step-by-step explanation:

The PROC TRANSPOSE procedure in SAS is used to reshape data by converting columns to rows or vice versa. By default, without any options or statements, PROC TRANSPOSE will transpose all the variables in the dataset.

This means option a) is correct.

The dataset's variables will become observations in the output dataset, and observations will become variables.

No data is deleted or reversed; the data's orientation is merely altered

. The result is a new dataset where the rows and columns have been interchanged.
