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. In the problems where the width of all classes is the same, then further simplify the calculations of the mean by computing the coded mean, i.e. the mean of u1, u2, u3, … un where, ui = (yi – a) c. then the mean is given by the formula, mean = a c x (Σfiui Σfi) this method of finding the mean is called the step deviation method. Calculating the mean using step deviation method. The step deviation method is a simplified way to calculate the mean of a grouped frequency distribution, especially when the class intervals are uniform. in simple words, statistics implies the process of gathering, sorting, examine, interpret and then present the data in an understandable manner so as to enable one to form an opinion of it and take necessary action, if necessary.
