![]() The Laerd Statistics Group states, “The mean, median and mode are all valid measures of central tendency, but under different conditions, some measures of central tendency become more appropriate to use than others.” This is why it is vital for students to know and understand how to calculate each of these three measures. That could help students decide what movies to see or what games to play based on their popularity. A question about what movie classmates are going to, or which video game they are playing at home would quickly reveal a mode. Students can also use the mode to quickly make decisions based on what others around them are doing. If a student wants to know how many books classmates read during a certain month, looking at the mode of that set of numbers would be a quick way to see what is typical for the class. The mode is a useful number to look at when trying to find trends within a group. If there were three 4’s and three 5’s in a set of numbers, and no other number occurred more than three times, there would be two different modes. That means it is possible for a set of numbers to have no mode, or to have more than one mode. For there to be a mode, a number has to occur more than once. You find the mode of a set of numbers by simply looking at which number within the set occurs the most often. They will be more invested in the work, and more motivated to find the answer. One of the best ways to help students learn how to figure out the mean of a set of numbers is to use something that is connected to their lives. ![]() They could then calculate an average time for each week and see how that average progresses from week to week. Students could go for a 3-kilometer run three times per week and keep track of how long that takes. They also might want to use this statistical category to measure progress on a task. Students might want to calculate the average score they have earned on a set of spelling or maths tests during the school year. This is one of the best areas to connect to real life so students will find the work more relevant. The answer is the average, which can be beneficial in a variety of settings. ![]() The total of those numbers is then divided by however many numbers were added up. The process is carried out by adding up all of the numbers in a set of data. Calculating the mean of a set of numbers by following a fairly simple process. This is the most often used measure of central tendency within a set of numbers. The mean mode is also often referred to as the average of a set of numbers.
