Here are some additional questions to consider:

1. What score has the lowest frequency in the dataset?
2. What is the total number of quiz takers, based on the histogram?
3. What is the median score based on the histogram distribution?
4. How would the mean score compare to the median in this dataset?
5. Are there any other scores that appear frequently, and how might this impact the analysis?

Tip: In a histogram, the height of each bar represents the frequency of data points in each category or interval, which makes it a useful tool for visualizing the distribution.
