When people describe the ‘average’ of a group of numbers, they often refer to the arithmetic mean. ![]() In this section, you’ll learn about the different types of averages and how they’re calculated and applied in various fields, especially in sports. These are just a few examples of how averages are used in When it comes to buying expensive products, we often ask theĪverage price to look for the best deals. In school, we ask the average score for a test to know if we Mean, Median and Mode: Data Trends, Detecting Anomalies, and Uses in Sports To figure the range subtract the smallest number from the largest number 27-3=24. The only number which appears multiple times is 3, so it is the mode. The 2 middle numbers only need to be averaged when the data set has an even number of data points in it. If there were 9 numbers in the series rather than 10 you would take the 5th number and would not need to average the 2 middle numbers. There are 10 total numbers, so the 5th and 6th numbers are used to figure the median. Example CalculationĬalculate the mean, median, mode and range for 3, 19, 9, 7, 27, 4, 8, 15, 3, 11. Range The difference between the largest and smallest data in a data set. Mode The value which occures most frequently in a data set. ![]() Median The value in a set which is most close to the middle of a range. Math Definition Mean The average of all the data in a set.
