What is Linear Regression?

Back

Linear Regression is a statistical method used to model the relationship between a dependent variable and one or more independent variables by fitting a linear equation to observed data.

What does the equation of a line in linear regression look like?

Back

The equation of a line in linear regression is typically written as y = mx + b, where m is the slope and b is the y-intercept.

What is the slope in a linear regression equation?

Back

The slope (m) indicates the rate of change of the dependent variable (y) for each unit change in the independent variable (x).

What is the y-intercept in a linear regression equation?

Back

The y-intercept (b) is the value of y when the independent variable (x) is zero.

How can you use a linear regression equation to make predictions?

Back

You can substitute a value for the independent variable (x) into the linear regression equation to calculate the predicted value of the dependent variable (y).

What does a trend line in a scatter plot represent?

Back

A trend line represents the general direction or pattern of the data points in a scatter plot, often indicating the relationship between the two variables.

How do you find the predicted value using a linear regression equation?

Back

To find the predicted value, substitute the given value of x into the linear regression equation and solve for y.
