About; Book; Handouts; Practice and Solutions; Stat 110 on YouTube; Stat110x on edX;Basically, we multiply the numbers altogether and take the nth root of the multiplied numbers, where n is the total number of data values. For example: for a given set of two numbers such as 3 and 1, the geometric mean is equal to √ (3×1) = √3 = 1.732. In other words, the geometric mean is defined as the nth root of the product of n numbers.Step 5: In this step, we have to find the total of fi denoted by N, and calculate N/2. Step 6: here, we have to locate the Cumulative Frequency which is greater than or equal to N/2. Note down its corresponding Median Class as well. Step 7: We have to use the formula given below to calculate the Median. M = L + (. ….
