Question

question 3 which of the dot plots below only has one mode? option 1 option 2 option 3 option 4

Explanation:

Step1: Recall mode definition

The mode is the value that appears most frequently in a data - set. In a dot - plot, it is the value with the most dots above it.

Step2: Analyze Option 1

In Option 1, the value 30 has the most dots above it, and no other value has the same number of dots. So it has one mode.

Step3: Analyze Option 2

In Option 2, both 30 and 70 have a relatively high and equal number of dots. So it has two modes.

Step4: Analyze Option 3

In Option 3, both 40 and 50 have a relatively high and equal number of dots. So it has two modes.

Step5: Analyze Option 4

In Option 4, both 60 and 70 have a relatively high and equal number of dots. So it has two modes.

Answer:

A. Option 1
