Play to Learn
Goal(s): Learn that the Z test provides the exact location of the observed sample mean (relative to the center of the sample means distribution). See how the Standard Error of the Mean and the Z test are calculated. Develop experience regarding when to reject the null hypothesis.
How: For each scenario presented, decide based upon the Z test, whether the results are statistically significant. Make 30 quick decisions, with immediate feedback

For this game, a red dot is used to represent the sample mean.
The null hypothesis states that the population mean is in the middle of the distribution of sample means. Thus, based on the null hypothesis, we expect the sample mean to occur near the middle of the distribution.
For this two-tailed hypothesis test, reject the null hypothesis when the Z-test is either [a] 1.96 or greater or [b] -1.96 or less.
Treat this game as an opportunity to observe how the both Standard Error of the Mean and the Z Test are calculated. The Z Test indicates the number of standard errors the sample mean is from the Null specified population mean.
