How To Solve Problems Based On Mean Of Continuous Frequency Distribution By Step Deviation Method

How To Solve Problems Based On Median Of A Continuous Frequency Find the mean of the following distribution using the step deviation method. solution: here, the intervals are of equal size. so we can apply the step deviation method, in which. a = a l ∙ ∑di′fi ∑fi ∑ d i ′ f i ∑ f i. where a = assumed mean, l = common size of class intervals. fi = frequency of the ith class interval. di. In continuous series (grouped frequency distribution), the value of a variable is grouped into several class intervals (such as 0 5,5 10,10 15) along with the corresponding frequencies. the method used to determine the arithmetic average in a continuous series is the same as that used in a discrete series.

How To Solve Problems Based On Mean Of Continuous Frequency Step deviation of mean = a h [∑u i i f i i ∑f i i] = 100 20 [65 100] = 100 13. = 113. therefore, the mean of the data is 113. example 2: find the mean percentage of the work completed for a project in a country where the assumed mean is 50, the class size is 20, frequency is 100, and the product of the frequency and deviation is. Steps to calculate mean deviation of continuous frequency distribution. to calculate the mean deviation for continuous frequency distribution, the following steps are followed: step i) assume that the frequency in each class is centered at the mid point. the mean is calculated for these mid points. considering the above example, the midpoints. How to compute mean deviation of continuous frequency distribution. to find the mean deviation for continuous frequency distribution, we follow these steps: step 1) assume that the frequency in each class is centered at the mid point. we then calculate the mean for these mid points. for the above example, the midpoints would be: weight category. Multiply the step deviations with the frequencies and take up the sum of the numbers so obtained. apply the formula: , where Σd1 is the sum of all the step deviations multiplied by respective frequencies and c represents the common factor. the number so obtained is the arithmetic mean of the given data set. thus, the formula for the.

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. Steps to calculate mean deviation of continuous frequency distribution. to calculate the mean deviation for continuous frequency distribution, following steps are followed: step i) assume that the frequency in each class is centered at the mid point. the mean is calculated for these mid points. considering the above example the mid points are.
