To calculate the mean, median, mode and range, we need to manipulate this data using the information about how to find each particular average above. The following data set is from a game that a group of students were playing in the classroom. To find an average, you must first have a data set.
When dealing with data that contains outliers, finding the mean may not always be the best option. It is useful for students to be aware of mean, median, mode and range despite it not being an explicit requirement, as an introduction at this stage proves useful for later years. Mean, median, mode and range in math curriculum
The range is the difference between the largest value and the smallest value. The mode is the value that appears the most number of times in a data set. The median is the middle value (or midpoint) after all the data points have been arranged in value order as a list of numbers. It is also known as ‘arithmetic mean’, rather than ‘geometric mean’. The mean is adding up all the data points and dividing the sum by the number of data points (or total number of numbers).
Mean, median and mode are different types of averages from a data set.
