This pre-algebra math tutorial from NutshellMath offers homework help in understanding and finding the mean, median and mode of a set of data.
As the teacher defines, the mean is the sum of a set of data, divided by the total number of elements in that set of data. The median is the middle element of a set of data when all elements are listed in order, smallest to largest. The mode is the most frequently occurring number in a set of data.
Examples and tips presented demonstrate how to find the mean, median and mode in various data sets. In finding the mean, the tutorial shows how to sum all the elements in a data set and divide by the total number of elements. For the median, the elements of the data set are ordered from smallest to largest and the middle element in the ordered list is the median. In data sets with an even number of elements, the mean of the two middle numbers is taken as the median. For the mode, the tutorial demonstrates finding the most frequently occurring element in a data set, and explains how a given set can have one, more than one, or no mode.
The mean, median and mode are statistical concepts of "central tendency", or evaluation of the "average" of a set of data. Understanding of the mean, median and mode is important for use with all sets of numbers, and as an introductory concept in statistics.
