Explanation Definition: Mean: Suppose the data set contains n data values, the mean x ¯ of the data is computing by the formula x ¯ = ∑ x n . Median: First arrange a set of data values in increasing or decreasing order. The median is the middle value in the list of arranged data values. Case 1: If there are an odd number of values, then the median is the value in the middle position. Case 2: If there is an even number of values, then the median is the mean of two middle values. Mode: “The mode of a set of data is the data value that occurs most frequently. It is possible for a data set to have more than one mode. If no one value occurs more than others, the data set is said to have no mode”. Calculation: From the definition of mean, it is used to compute the sum of the average value of the given distribution. Example: Consider the distribution 2, 3, 3, 4, 5. Here, n = 5 . Compute the mean of the distribution by using the mean formula mentioned above. x ¯ = 2 + 3 + 3 + 4 + 5 5 = 17 5 = 3
