What is the sum of the product of the frequencies and the square of the class marks (ΣfX²60,55,40,48,52,36,50?

Step 1: Find the midpoint of each interval. Step 2: Multiply the frequency of each interval by its mid-point. Step 3: Get the sum of all the frequencies (f) and the sum of all the fx. Divide 'sum of fx' by 'sum of f ' to get the mean. Determine the class boundaries by subtracting 0.5 from the lower class limit and by adding 0.5 to the upper class limit. Draw a tally mark next to each class for each value that is contained within that class. Count the tally marks to determine the frequency of each class. What is this? The class interval is the difference between the upper class limit and the lower class limit. For example, the size of the class interval for the first class is 30 – 21 = 9. Similarly, the size of the class interval for the second class is 40 – 31 = 9.
