Statistics

1. The Summary tab of the Analyze Results view includes:
   1. Test Reliability using a Cronbach's Alpha internal measure of test reliability, which determines the consistency of a test. The higher the reliability, the more likely you would produce similar results administering the same test to the same class
   2.  The class Mean and Highest and Lowest Scores
   3. The Standard Deviation, which is the percentage spread of scores from the mean. A smaller standard deviation means scores are "tightly" spread around the mean. Whereas, a high standard deviation indicates a large variation in exam results.
   4. Use the Export to drop-down to export exam results to a CSV file.
