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!
The mode of a data set is the number that occurs most often, but what if your data set has more than one mode? Is that possible? This tutorial explains what to do when a data set has multiple modes!
To find the mode of a data set, look for the number that occurs most often. What if all the numbers occur the same number of times? What's the mode of that data set? This tutorial will tell you!
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!

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.
In this word problem, you'll see how to use the Fundamental Counting Principle to find the number of possible lunch combinations! Take a look!
Finding the minimum, maximum, median, and quartiles of a set of data can help tell you a lot about your data. Follow along with this tutorial to practice finding these pieces of a data set!
Scientists often use probabilities to help find the chance of something occurring or not occurring. This word problem shows you how to find the probability of a complement. Then, you can also see how to find the probability of that complement happening 3 years in a row!
Simulators are a great way to model an experiment without actually performing the experiment in real life. This tutorial looks at using a simulator to figure out what might happen if you randomly guessed on a true/false quiz.
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!
