## What is the variable used to predict another variable called?

❖ The variable that is used to explain or predict the response variable is called **the explanatory variable**. It is also sometimes called the independent variable because it is independent of the other variable. In regression, the order of the variables is very important.

## What is regression quizlet?

Regression. **A statistical measure that attempts to determine the strength of the relationship between one dependent variable** (Y) and a series of other changing variables (independent variables)

## What does a coefficient of correlation of .70 infer?

what does a coefficient of correlation of . 70 infer? **strong**. if the correlation between two variables is close to one, the association is. y-intercept.

## What does a coefficient of correlation of .70 infer quizlet?

It describes the relationship between two variables. What does a correlation coefficient of 0.70 infer? **There is almost no correlation** because 0.70 is close to 1.0. 70% of the variation in one variable is explained by the other variable.

## What is the purpose of regression analysis quizlet?

The goal of regression analysis is **to develop a regression equation from which we can predict one score on the basis of one or more other scores**. Regression provides a mathematical description of how the variables are related and allows us to predict one variable from the others.

## What does a correlation of 0.25 mean?

Generally yes, a correlation of 0.25 is **considered substantial** (not necessarily high) depending on what you are looking at. I’ve also seen 0.3 as a cut-off point but we learned that a corr of 0.2 or higher already hints at a low positive correlation.

## What does a correlation of 0.7 mean?

## What is the general form of the linear regression equation?

A linear regression line has an equation of the form **Y = a + bX**, where X is the explanatory variable and Y is the dependent variable. The slope of the line is b, and a is the intercept (the value of y when x = 0).
