Question

Yasmine works as a server in a restaurant and earns different amounts in tips each night. Her earnings in tips over the course of 8 nights of work are shown in the following dataset. Find the mode of dataset and explain wether the mode is descriptive of the dataset.

{$10.45, $10.45, $35.80, $38.10, $40.90, $45.90, $79.60, $96.78} A or B?

A. The mode of the dataset is $10.45. The mode is descriptive of the dataset because it is the most common value.

B. The mode is $10.45. The mode is not descriptive of the dataset because it does not describe the center of the data.

Answer 1

Mode = $10.45 (it occurs twice, all other values occur once). Choose B.

Reason: although $10.45 is the most common value, it’s not descriptive of the dataset’s center — the median is $39.50 and the mean ≈ $44.75, so the mode is far below the typical tip amount.
