Question

A company wants to test a new dog food that

is supposed to help overweight dogs lose
weight. 50 dogs are chosen to get the new
food, and 50 more continue their normal diets.
After one month, the dogs are checked to
see if they lost any weight.

Answer 1

To ensure a fair comparison, the company should ensure that the two groups of dogs are similar in all aspects except for their diets.

Step-by-step explanation:

This is a scenario for a controlled experiment, where the company wants to test the effectiveness of new dog food by comparing it to the current diet of a group of dogs.

The experimental group consists of the 50 dogs given the new dog food, while the control group consists of the 50 dogs that continue their normal diets. The company will measure the weight of each dog in both groups before and after one month of the experiment.

To ensure a fair comparison, the company should ensure that the two groups of dogs are similar in all aspects except for their diets.
