StatCrunch Tutorial Videos
StatCrunch is a great statistical analysis app that resides on the web and thus works equally well for both PC and MAC users. If you are taking a stats course and do not have good Excel skills, I suggest you consider learning to use StatCrunch. My sense is that students find StatCrunch’s learning curve, the time and effort needed to get up to a reasonable skill level, is much shorter and not as steep as learning both basic Excel skills and how to use Excel’s statistical formulas to crunch the numbers. This is especially true for short time frame, i.e. 8-week term, introductory statistics classes.
StatCrunch homepage If you bought access to MyStatLab, which has StatCrunch embedded, you should be able to use your Pearson MySTatLab to log in here. If you no longer have access to MyStatLab, you can purchase a 6 or 12 month access key for $13.75/$24.20.

The hypothesis test is based on the Z statistic. The resulting statistic from the test drops into the plot. Red values are tests where the null hypothesis is rejected at the specified level of significance. Change the default significance level (set at 0.05) by adjusting the Level in the applet. 5 tests and 1000 tests add the hypothesis results ...
