This tutorial will help you learn how to find the mean or average of a given data set. You need to memorize the formula to find the average. You must combine the given numbers in your data, then divide by the quantity of numbers in your set. You will also learn how to show a fraction as division in order to get your mean.

Finding the mean of a data set video involves mean, sets, statistics. The video tutorial is recommended for 5th Grade, 6th Grade, 7th Grade, 8th Grade, 10th Grade, 11th Grade, and/or 12th Grade Math students studying Algebra, Probability and Statistics, Basic Math, Pre-Algebra, Pre-Calculus, and/or Advanced Algebra.

The most common type of average is the arithmetic mean, often simply called the mean. The arithmetic mean of two numbers, such as 2 and 8, is obtained by finding a value A such that 2 + 8 = A + A. It is then simple to find that A = (2 + 8)/2 = 5. Switching the order of 2 and 8 to read 8 and 2 does not change the resulting value obtained for A. The mean 5 is not less than the minimum 2 nor greater than the maximum 8. If we increase the number of terms in the list for which we want an average, we get, for example, that the arithmetic mean of 2, 8, and 11 is found by solving for the value of A in the equation 2 + 8 + 11 = A + A + A. It is simple to find that A = (2 + 8 + 11)/3 = 7.

A set is a collection of distinct objects considered as a whole. Sets are one of the most fundamental concepts in mathematics. The study of the structure of sets, set theory, is rich and ongoing.
