WebAlso, the data will be in the form of a frequency distribution table with classes. Thus, the formula to find the mean in assumed mean method is: M e a n, ( x ―) = a + ∑ f d i ∑ f. Here, a = assumed mean. f i = frequency of ith class. d i = x i – a = deviation of ith class. Σf i = N = Total number of observations. WebThe mean of 100 observations is 50 and the standard deviation is 10. If 5 is subtracted from each observation and then it is divided by 4, then what will be ...
