Question

formula to find out mean according to assumed mean method ?? give the answer in fill in the blanks​

Answer 1

Step-by-step explanation:

Hence we can use the step deviation method. Let the Assumed mean A = 20, n = 8. Example 8.8 Find the standard deviation of the following data 7, 4, 8, 10, 11. Add 3 to all the values then find the standard deviation for the new values

For ungrouped data, the formula for assumed mean is A+ sd/N where A is the assumed mean, sd is the summation of X-A for all figures and N is the frequency or the number of element in the given data.
