1. Summary of Class results (25 points): Discuss and cite specific data that accurately summarizes your class/sample performance on the given assessment. Talk about measures of central tendency (mean, median, mode, frequency distribution, curve, skewness, and objective performance) their meanings and interpretations and what implications do they have on future instruction (how should you use these results).

2. Item Analysis and Reliability (25 points): Discuss relative aspects and findings from your item analysis. What are some potential threats to these findings, how could they be improved and what implications do they have on future instruction (how should you use these results).
