Question

four students spun a spinner with 16 equal sections, numbered 1 through 16. andrea spun 50 times. dominique spun 5 times. raul spun 25 times. seth spun 20 times. use the results to answer the questions. which students data would be most representative of the spinner? which two students would have the largest changes between their data displays?

Explanation:

Step1: Recall sampling principle

The larger the sample size, the more representative the data.

Step2: Compare sample - sizes

Andrea spun 50 times, Dominique spun 5 times, Raul spun 25 times, and Seth spun 20 times. Since 50>25>20>5, Andrea has the largest sample - size.

Step3: Analyze differences in data displays

The larger the difference in sample - sizes, the larger the potential difference in data displays. The biggest difference in sample - sizes is between Andrea (50 spins) and Dominique (5 spins).

Answer:

Which student's data would be most representative of the spinner? Andrea
Which two students would have the largest changes between their data displays? Andrea and Dominique
