• How Do You Use a Tree Diagram to Count the Number of Outcomes in a Sample Space?

When you're trying to figure out all the possibilities from different options, it can be helpful to make a tree diagram. In this tutorial, you'll see how to use a tree diagram to figure out how many different outfits can be created from the possible shirts, bottoms, and shoes given. Check it out!

• How Do You Find the Probability of a Simple Event?

Working with probabilities? Check out this tutorial! You'll see how to calculate the probability of picking a certain marble out of a bag.

• How Do You Find the Probability of Independent Events?

Calculating probabilities? Take a look at this tutorial and see how to figure out the probability of independently drawing certain cards from a deck!

• How Do You Find the Probability of Dependent Events?

Sometimes probabilities depend on the outcomes of other events. Check out this tutorial to see probabilities of dependent events in action!

• How Do You Find the Mode of a Data Set?

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.

• How Do You Find the Range of a Data Set?

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!

• How Do You Find a Number of Combinations Using the Fundamental Counting Principle?

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!

• How Do You Use a Simulation to Solve a Problem?

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.

• What is an Outcome?

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!

• What is a Sample Space?

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!

• What is Probability?

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!

• What is the Median of a Data Set?

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!

• What is the Mode of a Data Set?

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!

• What is the Mean of a Data Set?

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!

• What is Experimental Probability?

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.

• How Do You Solve a Problem by Making an Organized List?

Organization is a big part of math. In this tutorial, you'll see how organizing information given in a word problem can help you solve the problem and find the answer!

• How Do You Determine All the Possible Outcomes of an Experiment?

When you perform an experiment, how do you figure out all the possible outcomes? Follow along with this tutorial to see!

• What is an Unbiased Sample?

When you're trying to learn about a population, it can be helpful to look at an unbiased sample. An unbiased sample can be an accurate representation of the entire population and can help you draw conclusions about the population. This tutorial introduces you to unbiased sampling!
