Complete SAS Programming Guide - Learn SAS and Become a Data Ninja - Arrays 2 (Constructing New Variables)

The video tutorial covers constructing new variables by adding tax to existing prices. It explains using arrays to manage old and new variables and demonstrates how to efficiently create multiple new variables using loops. The process involves calculating a 5% tax on original prices and printing the results. The tutorial emphasizes simplifying repetitive tasks through programming techniques.

What is the primary goal when constructing new variables in this tutorial?

• To create six new variables that include the price plus tax

• To delete old variables from the dataset

• To reduce the number of variables to three

• To categorize items into different groups

What is the purpose of creating arrays in the process of constructing new variables?

• To represent old and new variables for easier manipulation

• To delete unnecessary data

• To store the results of calculations

• To visualize data in a chart

How does the tutorial suggest simplifying the process of creating multiple new variables?

• By outsourcing the task

• By manually entering each variable

• By using a complex algorithm

• By using a single loop to automate the process

What percentage of tax is added to the original prices in the loop?

• 15%

• 20%

• 5%

• 10%

What can be done if you only want to display the tax amount without the original price?

• Add a new variable for the tax amount

• Subtract the original price from the total

• Delete the part of the code that adds the original price

• Multiply the original price by 0.1
