  1. Moving Averages. A moving average is used to compare a set of figures over time. For example, suppose you have measured the weight of a child over an eight year period and have the following figures (in kg): 32, 33,35, 38, 43, 53, 63, Taking the mean doesn't give us much useful information. However, we could take the average of each 3 year.
  2. Finding Average worksheets are about calculating the average of a set, or about finding the missing number sin a set given the average and set size. Once a math learner can calculate the average of a set, the more advanced average worksheets can be introduced.
  3. Dec 24,  · In math, an average is the concept of finding the middle of a set of data. Find averages with tips from a math teacher in this free video on solving math problems.
  4. Calculating an average is one of the easiest to solve problems in math. The numbers in the problem have to be added together and then divided.
  5. The term average has a number of different meanings. Most generally, it is a single number that is used to represent a collection of numbers. In the context of mathematics, "average" refers to the mean, specifically, the arithmetic mean. It is a relatively simple statistical concept .
  6. In mathematics and statistics, average refers to the sum of a group of values divided by n, where nis the number of values in the group. An average is also known as a mean. Like the medianand the mode, the average is a measure of central tendency, meaning it reflects a typical value in a given set.
  7. A calculated "central" value of a set of numbers. To calculate it: add up all the numbers, then divide by how many numbers there are. Example: what is the average of 2, 7 and 9?
  8. In working with an average, there is one central formula that is used to answer questions pertaining to an average. This formula can be manipulated in many different ways, enabling test writers to create different iterations on mean problems. The following is the formal mathematical formula for the arithmetic mean (a fancy name for the average).
  9. The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers. The "median" is the "middle" value in the list of numbers. To find the median, your numbers have to be listed in numerical order from smallest to largest, so you may have to rewrite your list before you can find the median.
