Central Tendency Use the following numbers: 1,3,2,5,4 Describe the following statistics: Mean Median Mode Draw a frequency distribution graph. Are these scores normally distributed?

Illustration of a Normal Curve

Using the Normal Curve Scenario: You administer a test that is normally distributed with a mean of 100 and a standard deviation of 15. Can a score of 90 be described as “average?” Can a score of135 be described as average?” What percentage of the population have a score of 130 or above? What percentage of the population has a score below 130?

Using the Normal Curve Scenario: You administer a test that is normally distributed with a mean of 100 and a standard deviation of 15. What percentile rank is a score of 85? What percentile rank is a score of 115? What is a z-score of a score of 85? What is a z-score of a score of 115? What is a T-score of a score of 70? What is a T-score of a score of 130?

Putting it to Use Psychometric Summary to Interpret Use this ranking for interpretation: 130 and above Upper Extreme 120-129 Superior 110-119 Above Average 90-109 Average 80-89 Below Average 70-79 Low 69 and Below Lower Extreme

Measuring Up Using the MMY provided to each group, go through and choose one test that you would find useful for your field of study. Discuss that test with your group.
