How To Solve Problems Based On Mean Of Grouped Data By Shortcut Method The arithmetic mean of the given data set is the number produced in this way. thus the formula for the calculation of arithmetic mean by short cut method is: sample problems. question 1: calculate the arithmetic mean for the following data set using the short cut method: solution: = 25 40 49. = 25 0.81. Learn how to solve problems based on mean of grouped data by shortcut method from this video. to view more educational content, please visit: you.
Standard Deviation Grouped Data The Shortcut Method Youtube In this video you will learn about all methods to find arithmetic mean through simple, shortcut and coding methods in both cases ungroup and group data. what. Learn how to find the mean of grouped data by shortcut method from this video.to view more educational content, please visit: appuser. There are two different formulas for calculating the mean for ungrouped data and the mean for grouped data. let us look at the formula to calculate the mean of grouped data. the formula is: x̄ = Σf i i n. where, x̄ = the mean value of the set of given data. f = frequency of the individual data. n = sum of frequencies. The three methods to find the mean of the grouped data is: direct method; assumed mean method; step deviation method. now, let us discuss all these three methods one by one. direct method. consider the same example as given above. now, convert the ungrouped data into grouped data by forming a class interval of width 15.

Step 2: choose a suitable value of mean and denote it by a. x in the middle as the assumed mean and denote it by a. step 3: calculate the deviations di = (x, a) for each i. step 4: calculate the product (fi x di) for each i. step 5: find n = ∑fi. step 6: calculate the mean, x, by using the formula: x = a ∑fidi n. Mean of grouped data methods. there are three methods to find the mean of grouped data. they are, (a) direct method (b) shortcut method (c) step deviation method . direct method. the arithmetic mean of a grouped data can be obtained through the direct method. the formula to find the arithmetic mean with the help of the direct method is as follows:.
