Describing Data Distributions from Graphed Data (Example)

The video tutorial discusses the results of a grade 6 math test, focusing on the frequency table and line plot. It identifies the lowest score as 64 and the highest as 100, with only one student achieving each. The scores are mostly grouped between 78 and 100, with a gap between 64 and 78, making 64 an outlier. The data is slightly skewed to the left, as the graph is not symmetric.

How many students achieved the lowest score on the test?

• Three students

• Two students

• One student

• Four students

What was the highest score achieved on the test?

• 100

• 105

• 95

• 90

Between which scores are most of the test results grouped?

• 64 and 78

• 100 and 120

• 78 and 100

• 50 and 64

What is the gap in the data that suggests an outlier?

• Between 90 and 100

• Between 64 and 78

• Between 50 and 64

• Between 78 and 90

How is the data skewed according to the graph?

• Skewed to the right

• Skewed to the left

• No skew

• Symmetric
