Answer #1

The correct option is :

B. The dependent variable is categorical variable

Reason: Consider the example where we want to predict whether a person is going to suffer from heart attack or not and this is our response/dependent variable and the independent variables are systolic blood pressure,age,education,diastolic pressure,cigarretes per day etc. So in this example our response variable Y is categorical,i.e,it takes the value 1 if a person is going to suffer from heart attack and 0 if the person is not going to suffer from heart attack. This is an example of a logistic regression where the response/dependent variable is binary/categorical.

A regression analysis is a statistical assessment of the association between two variables, one of which is dependent and the other, independent. The dependent variable is y and the independent variable is x. Regression analysis is used to find the relationships between these variables. Variables within a regression analysis can be negatively correlated or positively correlated. A situation in which one could model a regression analysis could be the association of hours studied and a grade on a test. The...
