Why is Data Collection & Analysis Important?

Anecdotes vs. Data

“Rescue groups

cherry pick all of the

highly adoptable

animals.”

In 2015, rescue partners pulled

1,500 animals. Of those:

• 30% Neonatal Kittens

• 30% Medical Needs

• 40% Highly Adoptable

Which is more useful for designing

and managing programs?

“The shelters are full

of nothing but pit

bulls.”

Pit Bull Type dogs make up 20% of

total dog intake. On average, pit

bull type dogs are held for 35 days

prior to an outcome versus 14 days

for other dogs.

Ways to Use Data Analysis to Drive Impact

• Identify new program opportunities

• Geo target S/N or TNR programs

• Monitor compliance with policy

• Determine Length of Stay

• Communicate with community

• Design adoption incentives

• Identify best/worst kennels

• Monitor program effectiveness

• Incentivize and reward staff

• Motivate volunteers and donors

• Identify opportunities for better process

Your Brain – Incredibly Powerful, Slightly Dangerous

11

Cognitive Bias

12

Cognitive bias describes the inherent thinking errors that humans

make in processing information. These thinking errors can prevent

us from accurately understanding reality, even when we have all the

needed data and evidence to form an accurate view.

Said another way, cognitive bias is the common tendency to

acquire and process information by filtering it through one's

own likes, dislikes, and experiences.

Negativity Bias

13

Negativity Bias is a tendency to notice, pay more attention, or give

more weight to negative experiences or information over positive.

What is an animal welfare example

of negativity bias?

Frequency Illusion

Frequency Illusion is the phenomenon in which people who just

learn or notice something start seeing it everywhere.

A Few Words on Shelter Software

18

• Different features and

functions mean no one

size fits all approach

• Data you input, you

should be able to extract

and analyze

• Standard and custom

reports usually available

• Use .csv or .xls exports

• Well worth having staff

and/or volunteer

member(s) with expertise

on your system

Google Sheets or Microsoft Excel?

18

• Free

• Cloud based

• Multiple users can be working

on or looking at

simultaneously

• Best for small data sets

• Will timeout if working on a

sheet with many tabs or more

than a few thousand rows

• Lots of add-ons for analysis

• Pivot tables are easier for

beginners

• Need a license

• Saved on your computer

• Only one user can be working

on, have to email versions

around

• Best for any data sets

• Can process lots of data

quickly

• No add-ons available, pretty

much everything you need is

built in

• Pivot tables are better

Demographic Data can be a Helpful Overlay

Demographics – The characteristics of

human populations and population

segments, especially when used to

identify consumer markets.

• Age, Race/Ethnicity, Income,

Education, Employment, Language

Spoken, Housing Type, Access to

Vehicle, etc.

Shelter Animals Count minimum data will allow you to calculate

release rates and do basic intake and outcome analysis.

Additional data will allow you to do deeper analysis that will benefit

your organization so we strongly suggest adding:

• Breed/Type

• Intake Address

• Length of Stay

Geographic Information Systems Also Powerful

Data Collection & Validation Tips

21

Things to do BEFORE you start an analysis

1. Identify what data you want to analyze and why

2. Verify how that data is currently being captured in your

system (i.e. who, when, how)

3. Consider whether the data is processed or modified after it

is entered (i.e. intact status)

4. Validate that data values are within realm of reality (i.e.

negative LOS)

5. Look for anomalies or outliers that need to be explored

Don’t Despair – Help is Available!

42

Where to look for help:

• Your local government

• Area universities

–Professors

–Class projects

–Interns

• Your volunteers!

• LinkedIn

Pivot Tables are Your Friend!!

29

A pivot table is a tool in Google Sheets & Excel that

allows you to explore large sets of data

interactively. Once you create a pivot table, you can

quickly transform huge amounts of data into a

meaningful summary.

Data Analysis Tips & Tricks

33

1. Look at numbers (#) and percentages (%)

2. Use graphs to visualize data; “Waterfall” style graphs are

especially useful

3. Use good graph hygiene; always start graph axis at zero to

avoid distortion

4. For comparison between graphs, keep same axis maximum

and scale

5. For comparison between geography, normalize per 1,000

human population

Correlation is NOT Causation

38

• Studies have shown that people who eat yogurt regularly have a

healthier body weight than those who do not eat yogurt regularly

• Can we therefore say that if you eat yogurt you will have a healthier

body weight? YOGURT CAUSES HEALTHY WEIGHT

• Or, might it be that people who make healthier diet choices overall

tend to eat more yogurt? HEALTHY PEOPLE EAT YOGURT

• We can say that eating yogurt is CORRELATED with healthy

weight, we cannot say that eating yogurt CAUSES healthy weight

• Most results have multiple contributing causes

• Resist the urge to oversimplify cause and effect

Data Interpretation Tips & Tricks

41

1. Don’t get too attached to your initial hypothesis, look for

other explanations

2. Remember that correlation does not imply causation

3. Recall that most outcomes are the result of multiple different

variables – resist the urge to over simplify!

4. Always ask yourself questions “What else could be going on

here?” “What else has changed?”

NKLA Program Started 2011

Used 2010 data analysis and community input to design several

programs with aim to make Los Angeles No Kill by 2017

Initial programs included:

• Grants for zip code targeted spay neuter (low income)

• Adoption subsidies for rescue groups

• Kitten nursery/foster programs

• New adoption facilities

• More kitten nursery/

intake

LENGTH OF STAY CASE STUDY

Do different transfer models impact LOS at Adopt &

Shop?

3 different transfer models1. A&S Staff select animals

2. Third Party select animals

3. Source shelter staff selects animals

Our assumptions• LOS will be lowest when the A&S staff

select the animals

• LOS will be highest when shelter staff select

animals since they may be sending those

that they cannot adopt

What data to analyze, and why?

• All animals by source shelter


• Eliminate records with negative LOS, eliminate

anomalies


• Average LOS by source shelter, grouped by transfer

model

Interpret and act. . . .source more animals from shelters

with a lower LOS?


• Date of outcome – Date of intake = LOS

• Total LOS / total number of entries = AVG LOS

LOS Collection & Analysis Process


Were our

assumptions

correct?


Is the

correlation

between how

the animal is

selected?

Or LRR?

What about

causation?

FOSTER CAPACITY CASE STUDY

What is it really going to take to save 1800 kittens?

2015 Statistics• ~200 foster homes

• <1000 kittens/mothers went

through program

• Minimal foster bottleneck

Assumptions• We are going to need A LOT of

new foster homes

Historical data to analyze

• AVG # litters per foster annually, AVG # kittens in a litter,

AVG LOS in a foster home


• Total # kittens fostered/total # litters = AVG # kittens per

litter

• Total # litters/total # foster homes = AVG # of litters per

foster home

How many fosters homes are needed to save 1800

kittens in 12 months?

Findings• 87% of our foster homes (FH) take 1-2 litters annually

• AVG litter size is 2 kittens

• 226 active foster homes

Calculations• 1800 kittens/2 kittens per litter = 900 litters

• 900 litters/2 litters per FH = 450 FHs needed

Optional Paths • Recruit an additional 224 FHs

• Increase # of kittens per litter (1800 kittens/3 kittens per litter = 600 litters/2

litters per FH = 300 FHs needed)

• Increase # of litters per FH (1800 kittens/2 kittens per litter = 900 litters/3 litters

• Increase # of kittens per litter and litters per FH (1800/3 kittens per litter = 600
