Group 3 Survey Data On Pets

I. Introduction

The purpose of this survey was to see the responses of the public on how many pets they have, how many hours a day are spent with the pets, pet type and whether or not the individual believes his/her health is better due to the pet.

The population sampled was pet owners.

The people that made up the sample were people in our lives (convenience sampling).

Some sampling methods that were used were social media, text, phone calls and word of mouth.

The four questions we used:

How many pets do you have?

How many hours per day do you spend with your pet?

What type of pet do you have?     Dog/Cat/Other

Do you believe your pet benefits your physical and/or emotional health?     Yes/No


II. Looking At A Categorical Variable

 A. The responses to "What Type Of Pet Do You Have?" are shown in the pie chart below.


Result 1: Pie Chart of C2   [Info]

The pie chart shows that over half of the respondents had dogs alone. Others still had dogs and other pets as well.

B. This bar plot shows the type of pet grouped by the responses to whether or not the pet affected health for the better.


Result 2: Bar Plot C1 grouped by C2   [Info]

The results show that most people felt their pets did positively impact their health. In those that didn't, results show that there isn't sufficient evidence that it had to do with the type of pet.


III. Looking At A Numerical Variable

A. For this section I used N1. Question N1 inquired about the number of pets respondents had.

Result 5: Summary Stats for N1   [Info]

Summary statistics:

# of Pets1071.88785051.00617181.00308110.096971513251612


The histrogram is skewed right. There are a large number of occurrences in the lower number values.The boxplot does have some outliers, those being 4 and 6. The numbers 4 and 6 as outliers are not very erroneous, especially when considering small pets that could exist in the "other category." The IQR is 1. The measures of center are 2 (median) and 1.8 (mean).

IV. Looking For A Relationship Between Two Numerical Variables

A. Scatter plot for N1 vs N2: The number of pets vs the hours of day spent with them.

Result 6: Scatter Plot N1 vs N2   [Info]

The scatterplot shows a weak negative trend with a lot of scatter. The outliers are 1 pet 24 hours, 3 pets 24 hours and 6 pets, 15 hours. 

B. Correlation for number of pets and hours per day spent is .018.

Result 7: Correlation for N1 and N2   [Info]
Correlation between # of Pets and Hours A Day is:

The absolute value of r is less than .196. Because of this we know that there is a not a statistically significant correlation between the number of pets and hours per day spent with them. We already knew this from the scatter plot.
