Answer 1

Regression

Question 2

is a best fitting line used for prediction

Answer 2

Regression Line

Question 3

What is the difference between correlation and regression?

Answer 3

orrelation measures the strength and direction of the relationship between two or more variables, while regression analyzes this relationship to make predictions about the values of one variable based on the values of another variable.

Question 4

A statistical technique designed to predict values of a dependent variable from knowledge of the values of one or more independent variable.

Answer 4

Linear Regression

Question 5

it uses the principle of ordinary least squares where line is drawn through a scatterplot that minimizes the sum of the squared residuals. In other words, a line is drawn close as possible to all the cases in the sample.

Answer 5

Linear Regression

Answer 6

simple prediction.
