Real Life Math: Average
August 11, 2011 · Posted in Real Life Math · Comment
An average is a number that expresses the central tendency of a group of numbers. Another word for average, one that is used more often in science and math, is “mean.” Averages are often used when people need to understand groups of numbers. Whenever groups of measurements are collected in biology, physics, engineering, astronomy or any other science, averages are calculated. Averages also appear in grading, sports, business, politics, insurance, and other aspects of daily life. An average or mean can be calculated for any list of two or more numbers by adding up the list and dividing by how many numbers are on it.
