# 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.

StatCrunch Examples: If you prefer written instructions, this page contains links to over 50 step-by-step instructions for most of the topics covered in this course.

StatCrunch playlist on YouTube A list of 93 StatCrunch video tutorials.

StatCrunch: Getting Started – Full Length 7:56-minutes on loading an external data file, calculating summary statistics and creating a simple column chart.

Note: if you are in MyStatLab, you may be able to load problem data directly into StatCrunch by clicking on the table icon as shown below: Videos 2 through 18 in the playlist are relatively short and to the point of the topic in the video title, mainly how to create various charts and tables. The remaining videos are also relatively short and to the point.
