Central tendencies can be described as finding a value in a set of data and finding its central point to identify its position. There are three main types of central tendencies; mean, median, and mode. These measures are all used differently to find central points in data sets. Here are some examples on when to use each value. Mean is used to find the average of something and divide that by however many there are in that group. For example, finding out the average height of 50 males between 18-25. Median is similar because it’s also finding the value that is approximately 50% of the data prescribed. For instance, we have 5 sets of data points pertaining to bicep size inches. The numbers are 10,12,14,15,16. The median for this set is 14. In order to find the median with 4 numbers, say 10,12,14,15, it would look like this: (12+14)/2 = 13. Lastly, mode can be defined as identifying the most frequent values in a particular set of data points. Let’s look at this example. We have 7,7,7,8,8,9,10. The mode for this set is 7 because
