Two or more binary, ratio level variables that are created from a nominal level variable are called:
A) independent variables
B) dependent variables
C) dummy variables
D) continuous variables

Question

Quizplus · Accepted Answer

When creating binary or ratio level variables from a nominal level variable, they are often referred to as dummy variables. Dummy variables are used to represent categorical data in regression analysis or other statistical models. The dummy variable takes on the value of 1 if the category is present and 0 if it is not present. Therefore, option C is the correct answer. Option A and D are both incorrect because they do not accurately describe the type of variables created from a nominal level variable. Option B is also incorrect because dependent variables are typically the outcome variable in a statistical analysis, not the variables created from a nominal level variable.
