Answer:
It's important to know how to calculate the mean or average of a set of numbers. Among other things, this will allow you to calculate your grade point average. However, you'll need to calculate the mean for several other situations, too. The concept of an average allows statisticians, demographers, economists, biologists, and other researchers
While averages can be very useful tools, they can also be misleading for a variety of reasons. In particular, averages can obscure the information contained in data sets. Here are a few examples of how averages can be misleading: 1. John's grades include a 4.5 in math, a 4.0 in science, a 2.0 in English and a 2.5 in History
In general, you calculate the mean or average of a set of numbers by adding them all up and dividing by how many numbers you have. This can be defined as follows: For a set of numbers, {x1, x2, x3, ... xj} the mean or average is the sum of all "x" divided by "j"
Let's start with an easy example. Calculate the mean of the following set of numbers: 1, 2, 3, 4, 5 To do this, add up the numbers and divide by how many numbers you have (5 of them, in this case). mean = (1 + 2 + 3 + 4 + 5)/5 mean = 15/5 mean = 3 Here's another example of calculating the mean. Calculate the mean of the following set of numbers: 25
