For the calculation of R squared, you need to determine the Correlation coefficient, and then you need to square the result. R Squared Formula = r2 Where r the correlation coefficient can be calculated per below: r = n (∑xy) – ∑x ∑y / √
It doesn't only calculate but it also shows the steps on how it was calculated, so all are install to solve our maths problems, this is very good app, this app is an absolute life saver.

Especially, once I got to the more challenging units the app is very informational and informative, but this literally does the work for me and helps me better understand 😁.

I can now correct any mistakes I made on the way to the result and sometimes checking for an idea to start solving. As soon as I press the red button it un-focuses and doesn't work. Very well made, but the focus on the camera is buggy. Its also have the feature of searching your own book.

It always lie between -1 and +1 which represented by -1 ≤ r (X, Y) ≤ 1. if r (X, Y) = 1 then the variables X and Y are positively correlated. if r (X, Y) = -1 then the variables X and Y are negatively correlated. if r (X, Y) = 0 then there is no
