Question

which line plot describes this data set? 91, 90, 91, 92, 88

Explanation:

Step1: Count the frequency of each number

• For \(88\): occurs \(1\) time.
• For \(90\): occurs \(1\) time.
• For \(91\): occurs \(2\) times.
• For \(92\): occurs \(1\) time.

Step2: Analyze the line - plots

• In the first line - plot:
• At \(88\): \(1\) \(X\)
• At \(89\): \(1\) \(X\) (but \(89\) is not in the data set \(\{88,90,91,91,92\}\))
• In the second line - plot:
• At \(88\): \(1\) \(X\)
• At \(90\): \(1\) \(X\)
• At \(91\): \(2\) \(X\)s
• At \(92\): \(1\) \(X\)

Answer:

The second line - plot.
