Linear, Multiple Regression Interview Questions Set 1

Logistic regression quiz question and answers

This page lists down the practice tests / interview questions and answers for Linear (Univariate / Simple Linear) / Multiple (Multilinear / Multivariate) regression in machine learning. Those wanting to test their machine learning knowledge in relation with linear/multi-linear regression would find the test useful enough. The goal for these practice tests is to help you check your knowledge in numeric regression machine learning models from time-to-time. More importantly, when you are preparing for interviews, these practice tests are intended to be handy enough. Those going for freshers / intern interviews in the area of machine learning would also find these practice tests / interview questions to be very helpful.

Note that this is a series of tests which represents questions covering following topics:

  • Concepts related with simple linear regression and multi-linear regression
  • R-squared and Adjusted R-squared
  • Tests such as T-test, ANOVA tests for hypothesis testing

Other tests in the series includes some of the following:

In _________ regression, there is ________ dependent variable and ________ independent variable(s)

Correct! Wrong!
