Assumed Mean Method Formula Steps Examples In statistics, the assumed mean method is used to calculate mean or arithmetic mean of a grouped data. if the given data is large, then this method is recommended rather than a direct method for calculating mean. this method helps in reducing the calculations and results in small numerical values. Learn and understand how to calculate arithmetic mean using different methods of assumed mean and step deviation in different cases including grouped frequen.
Arithmetic Mean Direct Method Assumed Mean Method Cbse Ics Assumed mean method formula, methods and important. Calculate the arithmetic mean of the following data by direct method. solution : now we have to use the formula given above to find the arithmetic mean. arithmetic mean = ∑fx n = 390 5. = 15.6. hence the required arithmetic mean for the given data is 15.6. example 2 :. Steps to find mean using assumed mean method. for process for calculating mean by using assumed mean method, are discussed below: step 1: for each class interval, we have to calculate the class mark by using the formula, xi = (upper limit lower limit) 2. step 2: choose an approximate and suitable value of mean, and denote it by “a” . Assumed mean method. the next method to calculate the estimated mean for a group of data is the assumed mean method. in the direct method, we know the observations and the corresponding frequencies. in the assumed mean method, let us assume that a is any assumed number which the deviation of the observation is d\( i\) = x\( i\) a.

Assumed mean method: formula, steps, types & examples. Assumed mean. in statistics the assumed mean is a method for calculating the arithmetic mean and standard deviation of a data set. it simplifies calculating accurate values by hand. its interest today is chiefly historical but it can be used to quickly estimate these statistics. there are other rapid calculation methods which are more suited.
