Here are the formulas for Mean and Variance as shown in the image: MEAN Sample Mean: x = ( x)/(n) Population Mean: = ( x)/(N) Mean for grouped data (or weighted mean): x = = ( fx)/( f) VARIANCE Sample Variance (computational formula): S^2 = (1)/(n-1) ( x^2 - (( x)^2)/(n)) Sample Variance (definition formula): S^2 = (x-x)^2n-1 Sample Variance for grouped data: S^2 = f(x-x)^2n-1 Population Variance (definition formula): ^2 = ( (x-)^2)/(N) Population Variance for grouped data: ^2 = ( f(x-)^2)/(N) Population Variance (computational formula): ^2 = (1)/(N) ( x^2 - (( x)^2)/(N)) Relationship between n, N, and f n = N = f Let me know if you have a specific problem to solve using these formulas! 📸
