Video demonstrates using t-statistics to answer a question involving hypothesis testing with a small sample. Explains how to read a t-table and use it for a one-tailed test. [9:04]

Video expands on medical example from previous video and explains the difference between a one-tailed and two-tailed hypothesis test, when they would be used, and gives an example of calculating a one-tailed test. [6:34]

This lesson looks at a hypothesis test for one proportion in a problem about Snapchat use among teenagers. Includes downloadable study guide with exercises - guide also covers other topics. [11:34]

This lesson explains the process for doing a hypothesis test about an unknown population parameter by examining required conditions and assumptions, calculating the test statistics, finding the p-value, and stating the conclusion....

Video gives an example of a hypothesis test calculation involving the proportion of the population that has internet access given a large sample size. Discusses finding a critical z-score to determine whether to reject the null...

Video demonstrates the steps of a hypothesis test involving comparing population proportions. It shows setting up the null and alternative hypotheses and the steps used to calculate a z-statistic for the difference of the proportions and...

Video explains what a Type 1 error is both verbally and using graphics. [3:24]

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.

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....
