Mean of Grouped Data. The mean (or average) of observations, as we know, is the sum of the values of all the observations divided by the total number of observations. If x1, x2,. . ., xn are observations with respective frequencies f1, f2, . . ., fn, then this means observation x1 occurs f1 times, x2 occurs f2 times, and so on.
Find Mean, Median, Modal Class from Grouped Data. Example 1. The number of goals scored by Premier League teams over a weekend was recorded in a table. Calculate the mean and the mode. Calculating the Mean: If there are large amounts of data, it is easier if it is displayed in a frequency table. Large quantities of data can be much more easily viewed and managed if placedingroupsin afrequency table. Grouped data does not enable exact values for the mean, median and mode to be calculated. Alternate methods of analyising the data have to be employed. Example 1. During 3 hours at Heathrow airport 55 aircraft arrived late.
