Which question would most appropriately demonstrate the statistical concept of the mean?

The question about how many pets a family has is most appropriate for demonstrating the statistical concept of the mean because it asks for a numerical value that can be summed up. The mean, often referred to as the average, is calculated by adding together a set of numerical values and dividing by the total number of values.

Asking about the number of pets allows for a quantifiable response from multiple families, enabling you to calculate a mean value. For instance, if you gathered data from a group of families, you could easily determine the average number of pets each family owns, providing a clear and applicable understanding of the mean.

In contrast, the other questions—about eye color, seasonal preferences, or favorite animals—do not yield numerical answers. They are categorical in nature, which cannot be analyzed through the mean since they do not provide numbers that can be averaged. This distinction makes the question regarding the number of pets the most suitable for illustrating the concept of the mean in statistics.
