1. Based only on the level of

measurement (NOIR Scale) of the quiz scores, would the appropriate branch of statistics to analyze the scores be parametric or non-parametric? Explain.

2. Is the distribution of the Quiz 1 scores normal or skewed? Explain.

3. If the distribution of quiz scores is skewed, is the direction of the skew positive or

negative? Explain.

4. If quiz scores are normally distributed, would the appropriate branch of statistics used to analyze these data be parametric or non-parametric? Explain.

5. If distribution of quiz scores is skewed, would the appropriate branch of statistics used to analyze these data be parametric or nonparametric? Explain.

 

As a final step in this assignment, provide a short summary statement of your Histogram findings. In other words, what is your overall interpretation of the quiz scores for your class based on your analysis of the Histogram?
