●Population mean = μ = ( Σ Xi ) / N.
●Population standard deviation = σ = sqrt [ Σ ( Xi - μ )2 / N ]
●Population variance = σ2 = Σ ( Xi - μ )2 / N.
●Variance of population proportion = σP2 = PQ / n.
●Standardized score = Z = (X - μ) / σ

HOPE IT HELPS ✌

1.The mean for grouped data can be found by:
(¡) the direct method= x= sum of fi×xi/sum of fi
(¡¡) the assumed mean method:
x= a+ sum of fi×di/sum of d¡
(¡¡¡) the step division method:
x= a+{sum of f¡×u¡/sum of f¡}× h

2.Mode= l+{f¡-f0/2f¡-f0-f2}×h

3.Median=l+{n/2-cf| /f}×h
4. 3median=mode+2mean
