Question

A veterinarian is interested in determining whether or not an overweight dog would benefit more from daily 30 minute walks or from 30 minutes of daily play in a dog park. Design an experiment for the veterinarian, using 60 chubby dogs.

Answer 1

Step 1:

Out of the 30 chubby dogs. form two independents groups:

Group 1: Control Group: Chubby dogs of 30 Nos.

Group 2: Experimental Group: Chubby dogs of 30 Nos.

Step 2:

Randomly assign 30 dogs to each of the above 2 gropus.

Step 3:

Determine the characteristic which defines the benefit of an overweight dog: such as speed of running.

Step 4:

Measure the characteristic of interest for each of the 30 dogs in both the groups seperately.

Step 5:
Calculate the average of charateristic of interest foreach of the 2 groups seperately.

Step 6:
Conduct the experiment as folloes:
Group 1: Each of the 30 dogs in Group 1 for 30 minutes

Group 2: Each of the 30 dogs in Group 2 for more than 30minutes.

Step 7:
Calculate the improvement in due to the experiment for Group 1 and Group 2 seperately.

Step 8:

Use Hypothesis testing to test whether the improvement is statistically significant.

Step 9:

The confounding variables which can affect the experiment are to be kept controlled throughout the experimentation, such as diet for the dogsetc.
