![]() Let’s work out the median of the data set: The median splits a data distribution into two such that there are an equal number of values below as well as above it. The median is the middle value of a data set. Let’s get busy finding the median now! How to Find the Median of a Data Set ![]() ![]() Thankfully, math formulas are a lifesaver! Here’s the formula to calculate mean: This is the mean of the data set.īut what if the entire class of 15 participated? We would need to process huge amounts of data, and it would be difficult to rearrange it. Now to find the average number of cookies that can be stacked in a minute, we need to rearrange the cookie towers and distribute the cookies in such a way that all towers are equally tall.Īs you can see, each tower has 12 cookies. The arithmetic mean, or the typical average, is a measure that denotes the central location of a data distribution. Let’s get started with finding the mean now! How to Find the Mean of a Data Set Greg, Hannah, Amanda, Jake, and Sandra are tasked with building a cookie tower each with the highest number of cookies they can use in a minute. Let’s take this scenario for instance and make a data set: Gathering data is the basic step in preparing a data set. To find the 3 Ms - the mean, median, and mode, and the range, we first need a data set to work on. Now, coming to range, it says how varied a data set is. ![]() The three measures of central tendency – mean, median, and mode – are nothing but different types of averages. Average is that single measure used to indicate where most of the data points are concentrated. To make sense of all the data that is collected and turned into information, we need a single value that will give us an overview of the entire data set. ![]()
