Click Open in Excel and perform a regression analysis.How do you find the equation of a regression equation?
The formula for simple linear regression is Y = mX + b, where Y is the response (dependent) variable, X is the predictor (independent) variable, m is the estimated slope, and b is the estimated intercept.How do you find the equation of a regression line for data?
To calculate slope for a regression line, you'll need to divide the standard deviation of y values by the standard deviation of x values and then multiply this by the correlation between x and y. The slope can be negative, which would show a line going downhill rather than upwards.- Linear regression is a statistical tool in Excel used as a predictive analysis model to check the relationship between two sets of data or variables. We can estimate the relationship between two or more variables using this analysis. For example, we can see two variables: dependent and independent variables.
