Answer #1

Answer:

C. Dummy Variable

Explanation:

We know that we use the codes such as 0 and 1 for coding the nominal data for the purpose of transformation of non-mathematical data into a ratio or numerical data. Such variables are called as dummy variables. For example, we use 0 for female and 1 for male while coding the data for analysis purpose.
