Question

In a regression model of student grades, we would code the nine categories of business courses taken (ACC, FIN, ECN, MGT, MKT, MIS, ORG, POM, QMM) by including nine binary (0 or 1) predictors in the regression. Group startsTrue or False

Answer 1

Binary predictors are simply used to represent dummy variables in regression.

The statement that the nine categories can be coded by nine binary predictors is false.

Binary predictors can only take any of the two binary values (0 and 1).

This means that, the nine categories cannot be represented using binary values or predictors

This is so because, the number of categories (9) is greater than the number of predictors (2).

Hence, the given statement is false
