In this lesson, you will learn about the very important topic of p-values in statistics. The p-value is a calculation that you make during hypothesis testing to determine if you reject the null hypothesis or fail to reject it.

In this cool science experiment, you will see how you can put a balloon directly into a candle flame and the balloon will not burst. The power of heat conduction makes this possible. Have fun while learning about heat transfer and energy...

Learn how to write the null and alternate hypothesis as part of a hypothesis test in statistics. This video will show several examples so that the student gains an understanding of how to work hypothesis testing problems step-by-step....

Learn to make a very impressive cloud form in a plastic bottle! By pumping air into an empty plastic bottle and quickly releasing the pressure, we can cool off the air and force the water to condense into a thick cloud. It's a very...

The student will learn the big picture of what a hypothesis test is in statistics in this video. Items discussed are terms such as the null hypothesis, the alternate hypothesis, statistical significance of a hypothesis test, and more....

In this video, you will learn how to solve inequalities in algebra that only have one variable. You will learn that solving inequalities is very similar to solving equations and many of the same rules apply. After we arrive at the...
