While all are measures of central tendency, there are important differences in what each one means and how they are calculated. Explore some useful tips to help you distinguish between the mean, median, and mode and learn how to calculate each measure correctly. In order to understand the differences between the mean, median, and mode, start by defining the terms.
The mean, or average, is calculated by adding up the scores and dividing the total by the number of scores. Consider the following number set: 3, 4, 6, 6, 8, 9, The mean is calculated in the following manner:. The median is the middle score of a distribution. To calculate the median. Consider this set of numbers: 5, 7, 9, 9, Since you have an odd number of scores, the median would be 9.
You have five numbers, so you divide 5 by 2 to get 2. The number in the third position is the median. What happens when you have an even number of scores so there is no single middle score? Consider this set of numbers: 1, 2, 2, 4, 5, 7. Since there is an even number of scores, you need to take the average of the middle two scores, calculating their mean. Remember, the mean is calculated by adding the scores together and then dividing by the number of scores you added.
Then, you take 6 and divide it by 2 the total number of scores you added together , which equals 3. So, for this example, the median is 3. Since the mode is the most frequently occurring score in a distribution, simply select the most common score as your mode.
Consider the following number distribution of 2, 3, 6, 3, 7, 5, 1, 2, 3, 9. The mode of these numbers would be 3 since three is the most frequently occurring number. In cases where you have a very large number of scores, creating a frequency distribution can be helpful in determining the mode. In some number sets, there may actually be two modes. This is known as bi-modal distribution and it occurs when there are two numbers that are tied in frequency.
For example, consider the following set of numbers: 13, 17, 20, 20, 21, 23, 23, 26, 29,
