Assuming I have these data (or these values x and y): … Web8 apr. 2024 · The formula for linear regression equation is given by: y = a + bx a and b can be computed by the following formulas: b= n ∑ xy − ( ∑ x)( ∑ y) n ∑ x2 − ( ∑ x)2 a= ∑ y − b( ∑ x) n Where x and y are the variables for which we will make the regression line. b = Slope of the line. a = Y-intercept of the line. X = Values of the first data set. WebThe t score formula is: Where x̄ = sample mean μ 0 = population mean s = sample standard deviation n = sample size If you have only one item in your sample, the square root in the denominator becomes √1. This means the formula becomes: In simple terms, the larger the t score, the larger the difference is between the groups you are testing. palestinian interior minister
