With this statistical calculator, you will learn how to calculate the arithmetic mean of a distribution point series (grouped data).

The arithmetic mean will be 4+6+8+6+8+4+6 7 = 42 7 = 6 4 + 6 + 8 + 6 + 8 + 4 + 6 7 = 42 7 = 6. However, sometimes we have data already grouped or for statistical purposes we need to present them in groups. From our example, we can create the following groups: group of fours - frequency 2; group of sixes - frequency 3; group of eighth - frequency 2.

Mean of Grouped Data. In statistics, we have studied the classification of data into a grouped and ungrouped frequency distribution. These data can be pictorially represented using different graphs such as bar graphs, frequency polygons and histograms and so on. Also, we know that the three measures of central tendencies are mean, median and mode.
