Question

indicate whether each of the following two questions is a statistical question. explain why or why not.
a. how much does susans dog weigh?
b. how much do the dogs belonging to students at our school weigh?
if you collected data on the weights of dogs, would the data be numerical or categorical? explain how you know it is numerical or categorical.

Explanation:

a. A statistical question anticipates variability in the data. The weight of Susan's dog is a single - valued quantity with no variability expected in its answer. So it is not a statistical question.
b. The weights of dogs belonging to students at a school will vary from dog to dog. There will be multiple data points with different values, so it is a statistical question.
If data on dog weights is collected, weight is measured in numerical units (e.g., pounds or kilograms), so the data is numerical.

Answer:

a. Not a statistical question. There is no variability in the answer for the weight of a single dog.
b. Statistical question. There is variability in the weights of different dogs.
The data on dog weights is numerical because weight is measured in numerical values like pounds or kilograms.
