To find the mean, we add up all of the data values and then divide by the number of values. The equation for this is: {eq}\frac{x_{1}+x_{2}+x_{3}+...+x_{n}}{n}=\frac{\sum_{X}}{n} {/eq}, where n is the number of data points and {eq}x_{1}, x_{2},......
Calculating the Mean Score If you want to graph a curve based on a set of test results, you need the mean score. It defines the top of the curve and determines which of the people who took the test are "in front" of the curve and which are "behind" it. The process is easy: 1....
