Life enjoyment and pet ownership.

Do people experience more enjoyment for life when living with a dog?

100 people all living in the Phoenix area without any pets, were selected for this study. Each person was between 25-25 years old, living alone, in similar income brackets, and came from similar backgrounds.

Flyers and adverts were posted around town advertising the study. A wait period commenced until all 100 people had been selected and fit the requirements. This was a volunteer sample.

Foe one year, 100 people without pets completed weekly surveys on how they viewed their enjoyment of life on a scale of 1-100, with 100 being the best.
After this was done, each was given a dog around 5 years of age with similar temperaments and builds. They were to live with the dogs for the next year and do weekly reports on how they perceived their “zest for life”, i.e. how much they were enjoying their life. Food, money for vet bills, etc. were provided for the dogs. Check-ins were done once a month to see the treatment of the dog and ensure it was not being abused or neglected.

The original one-year study was considered to be the control group for which the results would be compared against.

There was no blinding or double-blinding, as the experiment was voluntary and everyone involved knew the complete details of the study.

# data[].attributes.body
There was no randomized block design, as everyone was individually participating.

# data[].attributes.body
There were no matched pairs.

# data[].attributes.body
There was no crossover design but it could have been done. However, it likely wouldn't have added anything to the overall results.

The sample size was of 100 people with an error margin of 10%. This could be lowered with a larger sample size but would require more materials and likely longer research times.

# data[].attributes.body
Replication would be difficult to do, as it is very difficult to find 100 people that are very similar let alone another 100. The length of the experiment would have to be extended by another 2 years which is annoying.

-At the end of the two years, all the surveys had collected and analyzed. The people were allowed to keep the dogs, provided they had been deemed as suitable pet owners.
-In the year without a dog, the mean rating of life enjoyment was 46%. The minimum was 0%, the maximum was 100%, the median was 50%, and the mode was 60%
-In the year of the dog, the average rating of life enjoyment was 89%.
-This showed a definite increase in life enjoyment from not having a dog to having a dog. However, with a margin of error of 10%, there is always a chance of the results being skewed or somewhat incorrect. This could be adjusted but it will never be 0%.
