![]() To do this, professionals add the two figures together and divide the sum by two. In this case, there are two digits in the middle of the sequence, so you can identify the median by calculating the average of those digits. Even numbersĭetermining the median or 'middle' number in a sequence with an even number of digits requires further steps. The median of this sequence is 9, as it has an equal number of digits on either side. Now rearrange the numbers in value order: In this case, the median is the number in the middle of the sequence after listing the figures in value order. The median is the middle number in a sequence and is easily identifiable when there's an odd number of figures. Here's an example of a sequence with negative numbers present: In this case, negative numbers function by subtracting the figure from the sum of the positive numbers. You can still calculate the mean for sequences, including negative numbers. This also works for sequences with larger numbers and helps condense large sums into smaller figures to use in data management systems. Here's an example of calculating the mean:ġ+12+3+5+2=23 (divide this sum by the total of numbers present=5) Typically, you can calculate the mean by adding up the numbers in the sequence and dividing them by the number of figures. The mean is the average of a set of numbers. This information can be beneficial when performing research studies, gathering information about customers and sales figures and summarising large amounts of data into an accessible and condensed format. They help determine the 'middle' number or the centre of a data set. Mean, median and mode are common mathematical expressions that represent averages in statistics. Related: What is a Coder?
