Answer

Explanation:

Step1: Analyze reaction - time data

The reaction - time data has no extreme outliers. The mean is a good measure to summarize the central tendency when the data is relatively symmetric. So for part (a), mean is appropriate.

Step2: Analyze salary data

The salary data has no extreme outliers. The mean can be used to represent the average salary. So for part (b), mean is appropriate.

Step3: Analyze favorite - animal data

We want to find the animal chosen most often. The mode is the value that appears most frequently in a data - set. So for part (c), mode is appropriate.

Answer:

(a) Mean (b) Mean (c) Mode
