Mindy wants to find out the average distance that each of her six friends can throw a ball. She asks six friends of similar sizes and ages to throw a ball as far as possible from the same starting point. Mindy notices that one friend throws the ball much farther than the other five do. She wants her results to be accurate. What should Mindy do?
1. Repeat the experiment for the person with the unusual result.
2. Repeat the experiment using a different friend as a replacement.
3. Repeat the experiment and ignore the results of the first experiment.
4. Repeat the experiment two more times and find averages for each of the six throwers.
