In statistics, we can calculate a regression line for two variables. A regression line is a line that best fits the data. The formula for the regression line is $y = mx + b$, where $m$ is the slope of the line and $b$ is the $y$-intercept.Slope...
If you need to calculate the standard error (SE) of the slope by hand, use the following formula: SE = sb1= sqrt [ Σ(yi- ŷi)2/ (n - 2) ] / sqrt [ Σ(xi-x)2] Find the critical value. When calculating the margin of error for a regression slope, use at-scorefor the cr...
The formula for the slopeaof the regression line is: a = r(sy/sx) The calculation of a standard deviation involves taking the positive square root of a nonnegative number. As a result, both standard deviations in the formula for the slope must be nonnegative. If we assume that there is...
While the formula method to calculate slope and intercept is easy, the benefit of using the scatter chart method is that you can visually see the distribution of the data points as well as the slope of the regression line. And in case you are anyway creating a scatter chart for your data...

First, we need to calculate the slope. Slope is the rise over run. Use the slope formula below: For this calculation, it doesn’t matter which point is 1 vs. 2. If the math is easier one way, go with it! I’ll enter the values for our two points: (1, 6) and (3,10) into...
