How To Find Mean Of Grouped Data By Step Deviation Method Youtube Step deviation method is a method of obtaining the mean of grouped data when the values are large. in statistics, there are three types of mean arithmetic mean, geometric mean, and harmonic mean. when the values of the data are large and the deviation of the class marks have common factors, the step deviation method is used. In many scenarios, the data is large and to make a meaningful study, the data has to be condensed as grouped data. so, in those scenarios, we have to convert the ungrouped data into a grouped data and then find the mean. the three methods to find the mean of the grouped data is: direct method; assumed mean method; step deviation method.
Maths Mean Of Grouped Data Step Deviation Method Statistics 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. This maths video explains how to find mean of a grouped data using step deviation method. this video is meant for students studying in class 9 and 10 in cb. Mean is an arithmetic average of the data set and it can be calculated by dividing a sum of all the data points with the number of data points in the data set. it is a point in a data set that is the average of all the data points we have in a set. in statistics, mean is the most common and frequently used method to measure the center of a data. 97. we’ll need this both for the mean and for the standard deviation. step 2: find the midpoint of each interval range. to find the midpoint, add the top and bottom of each interval range and divide by two. for example, the first interval range is 37 to 46, so the midpoint is: (37 46) 2 = 83 2 = 41.5.

The calculation of mean by step deviation method is illustrated in the table. assumed mean a a is taken to be 92.5 92.5 and the step h h is taken to be 5 5. this simplifies the calculations. another example of mean by step deviation method of grouped data is given in the table. the mean is computed by step deviation method. 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.
