Exam Scores Histogram
This histogram shows the distribution of scores on a 100-point biology exam. The bars group students into score ranges so an instructor can see where results cluster and whether there is a long lower or upper tail. Here, the most common range is 70–79, with fewer students at both extremes. A histogram is a useful complement to the class average because two classes can share the same average while having very different spreads. Use equal-width bins and state whether the upper boundary is included when precision matters. For decisions about teaching or assessment, review individual items and learning objectives alongside the distribution rather than relying on the chart alone.

Scenario
Reviewing a class assessment
Key decisions
- Bins: Group scores into readable ten-point ranges.
- Center: Identify where most scores occur.
- Threshold: Compare the distribution with the course pass mark.
When to reuse this
Use this histogram to review score spread for one assessment, not to judge individual students.
