Part a
The histogram provided summarizes the distribution of test scores. Describe the overall shape of the distribution (e.g., symmetric, skewed), identify the center (e.g., approximate median or mode), and comment on the spread (variability) of the data. Provide clear reasoning for your summary.
Comparing Histograms: A Frequency Analysis
Two histograms display the frequency distribution of data from two separate studies. Compare the two histograms and identify at least two major differences in their distributions. In your response, clearly compare and contrast their shape, spread, and central tendency.
