Assumed Mean Method For Grouped Data Class 10 Youtube Below are some examples of calculating the mean of grouped data by this method. example 1: the following table gives information about the marks obtained by 110 students in an examination. find the mean marks of the students using the assumed mean method. solution: assumed mean = a = 25. The term "mean" refers to the arithmetic average of the data set and is derived by dividing the total number of data points by the number of data points in the set of data. it is a point that represents the average of all the data points in the set. the arithmetic mean of the grouped data is called the assumed mean.
How To Find The Mean Of The Grouped Data Assumed Mean Method Chapter We go over how to calculate the mean of grouped data sets using the assumed mean method. this method to calculate the mean requires us to guess the mean of t. Cbse class 10 maths notes chapter 14 statistics. mean (average): mean [ungrouped data] – mean of n observations, x 1, x 2, x 3 … x n, is. note: frequency of a class is centred at its mid point called class mark. (ii) assumed mean method: in this, an arbitrary mean ‘a’ is chosen which is called, ‘assumed mean’, somewhere in the. Such a table is called grouped data. mean. for ungrouped: consider ‘n’ observations in ungrouped data as : x 1, x 2, x 3, …. x n. the mean of these observations is: (i) direct method: where ‘f i ‘ is the frequency corresponding to the class mark ‘x i ‘ (ii) assumed mean method: where a is assumed mean and d i = x i – a (iii. Steps to compute mean of grouped data using step deviation method: we can use the following steps to compute the arithmetic mean by the step deviation method: step 1: prepare the frequency table in such a way that its first column consists of the observation, the second column the respective frequencies and the third column for the mid values.
