How could we describe the distribution of scores for each graph? What’s the same, what’s different?

Each of these cumulative frequency graphs show the test scores for different science classes. How can we describe the results represented by each graph? How do the results relate to the median? Even distribution of students across the range of scores. 2 Cumulative Frequency 1 Most students scored near the median. There are equal amounts of high & low scores. Cumulative Frequency Interpreting the Shapes of Cumulative Frequency Graphs Score Nearly all students scored near the median. Cumulative Frequency Few students scored high marks 4 Cumulative Frequency 3 Score Most students scored very high or very low marks. Cumulative Frequency Most students scored high marks 6 Cumulative Frequency 5 Score High median score. Score Cumulative Frequency Low median score. 8 Cumulative Frequency 7 Score ① ②

③ 8 classes took a science test & their results are described below. Sketch a cumulative frequency curve for each description. Think about the rate the cumulative frequency increases above and below the median.
