Basic statistics.1. find the percentCent = The frequency with which you want to compare the total number of samples/× 100.2. find out the average rating is calculated from the formula. X ̅=(∑▒X)/NWhen Χ rather than average scores.Instead, the sum of all scores ΣΧN represents the number of students in the experimental group.3. find the standard deviation (S) of the points. Calculated from the formulaS.D=√((n∑▒〖X^2-〖(∑▒X)〗^2 〗)/(n(n-1)))When the standard deviation of the scores instead of S.D.Σ X instead of the sum of all the scores.Σ X 2 instead of the sum of the squares of each score.N represents the number of students in the experimental group.
