Question

When a dummy variable is included in a multiple regression model, the interpretation of the estimated slope coefficient does not make any sense anymore.

a. True
b. False

Answer 1

Answer: b. False

Explanation:

• A dummy variable is a numerical variable used in regression analysis to represent values for categorical data by using value 0 (shows absence of particular category) or 1 (shows presence of particular category) .
• We cannot use categorical data to evaluate the slope coefficient (numerical value) until we convert them into dummies.

Hence, the given statement is absolutely false.
