Data Creation for Proportions Test

The script implements a DATA step to build the 'practice1' dataset. This dataset contains three variables: 'soda' (character, beverage preference), 'animal' (character, animal preference) and 'weight' (numeric, representing counts). The data is directly integrated via the `datalines` block. Script comments indicate an intention to later use PROC FREQ with the CHISQ option to test the independence between beverage preference and pet preference, using the 'weight' variable as frequency weights. However, PROC FREQ itself is not present in the provided code snippet.

Data Analysis

Type : CREATION_INTERNE

The 'practice1' dataset is created directly within the script using a DATA step and `datalines`. No external or SASHELP data sources are used for this dataset's creation.

DATA STEP Data

Explanation :
This code block uses a DATA step to create a dataset named 'practice1'. It defines three variables: 'soda' and 'animal' as character (indicated by '$'), and 'weight' as numeric. The data is then provided inline via the `datalines` block, representing beverage preferences (Coke or Pepsi) and animal preferences (Dog or Cat), along with corresponding counts. This dataset forms the basis for future statistical analyses.
