In statistics, simple linear regression is a linear regression model with a single explanatory variable. One type of regression analysis is linear analysis. When a correlation coefficient shows that data is likely to be able to predict future outcomes and a scatter plot of the data appears to form a straight line, you can use simple linear regression to find a predictive function. If you recall from elementary algebra, . The result is a linear regression equation.
To do this you need to use the Linear.
In simple linear regression , we predict scores on one variable from the scores on a second variable. The variable we are predicting is called the criterion variable and is referred to as Y. Summary formula sheet for simple linear regression. Correlation coefficient is non-parametric and just indicates that two variables are associated with one another, but it does not give any ideas of the kind of relationship.

In statistics, you can calculate a regression line for two variables if their scatterplot shows a linear pattern and the correlation between the variables is very strong (for example, r = 8).
