Formula for Standard Deviation for Grouped data, when, \(Xg = Mid-point \ of \ each \ groups \ is \ taken \) and, any convenient group may be taken as working mean (\(w\)) → \(f = frequency \ of \ each \ group\) → Working units are denoted as, _____ where, \(i = Group \ interval\) → Then, deviation of group in working units is derived by \(f \times x\) → Squared deviation of groups is \(= f \times x^2\) Mean in working units is given by : \(\bar x = \frac {\sum fx}{n}, \) and True Mean is given by \(\bar X = w \ + \ \bar x \times i\) Standard deviation in working units is _____ True SD is, _____
