Math exercises on statistics in the fourth grade with calculation of total number, frequency in percent and average of a statistical series will be beneficial to you. Thus, statistics is a branch of mathematics that deals with the collection, analysis, interpretation, presentation and organization of data. Statistics exercises may include calculations of means, frequencies, and ranges, as well as the use of charts and graphs to represent and analyze data. The mean of a data set is a measure of the central value of the data. It can be calculated by adding all the elements in the data set and dividing the result by the total number of elements.
