Histogram Assignment

This assignment refers to the Histogram shown bellow
(see attached file) that depicts the
distribution of a set of quiz scores. Q 1 requires application of
learning from Module 9 combined with new learning from Module 10. Q’s 2-6 require your interpretation of the Histogram.

NOTE: You must answer ALL of the following questions.

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 non-parametric? Explain.
6.
Provide a short summary statement of your Histogram findings. In other
words, what is your overall interpretation of class performance on the
quiz based on your analysis of the Histogram?
