Mean is just another name for average. To find the mean of a data set, add all the values together and divide by the number of values in the set. The result is your mean! To see an example of finding the mean, watch this tutorial!
The median of a data set is the number that is the middle value of the set. It's easy to find the median if you first put the numbers in order from least to greatest. In this tutorial, see how to find the median of a data set, and see what to do if there are two middle values!
The mode of a data set is the number that occurs most frequently in the set. To easily find the mode, put the numbers in order from least to greatest and count how many times each number occurs. The number that occurs the most is the mode! Follow along with this tutorial and see how to find the mode of a set of data.
The range of a data set is the difference between the largest number and the smallest number. In this tutorial, you'll see how to find the range of a set of data. Check it out!
If you want to see data from a frequency table in a more visual way, try creating a histogram to show off that data! This tutorial shows you what to do!
A box-and-whisker plot can help you get a better picture of what your data looks like visually. This tutorial shows you the step-by-step process for making a box-and-whisker plot!
Frequency tables help you more easily see what occurs most often in a set of data. This tutorial shows you how to create a fequency table for a given set of data.
The Fundamental Counting Principle (FCP) can be used to find a number of permutations. Follow along with this tutorial to see how to use the FCP to find the number ways you can rearrange the letters in the word NUMBER.
Probability can help you solve all sorts of everyday problems! This tutorial shows you how to find the probability of the complement of an event using gummy worms!
The mean and median can help you better understand a data set. Check out this real world example involving finding and comparing the mean and median of multiple data sets.
When you're conducting an experiment, the outcome is a very important part. The outcome of an experiment is any possible result of the experiment. Learn about outcomes by watching this tutorial!
In an experiment, it's good to know your sample space. The sample space is the set of all possible outcomes of an experiment. Watch this tutorial to get a look at the sample space of an experiment!
The Fundamental Counting Principle is a way to figure out the total number of ways different events can occur. In this tutorial, you'll be introduced to this principle and see how to use it in an example. Take a look!
Probability can help you solve all sorts of everyday problems, but first you need to know what probability is! Follow along with this tutorial to learn about probability!
The median is one of many measures of central tendency. Check out this tutorial to learn what the median is and how you can find it!
Finding the mode of a set of data can help you understand the data better. This tutorial introduces you to mode and shows you how to find this helpful measure of central tendency!
When you think of the mean of a data set, think of the word average. 'Mean' and 'average' are the same thing when you're talking about a set of data! This tutorial introduces you to mean and shows you how to find it!
Stem-and-leaf plots can be really helpful in visually interpreting data. This tutorial introduces you to stem-and-leaf plots, shows you how to use this special type of graph, and explains some of the popular uses. Take a look!

Frequency tables tell you how often something occurs in a set of data. This tutorial introduces you to frequency tables and shows you some of the ways they can be used to interpret data!
Being able to disect a set of data and better understand it is a key part of mastering statistics. This tutorial teaches you about one of these disection tools called the interquartile range.
Do real life situations always work out the way your mathematical models tell you they should? No! This tutorial describes how experimental probability differs from theoretical probability.
When you learn about probablilities, the complement of an event is a must-know term! This tutorial introduces you the complement of an event.
