2. HANDS-ON OPEN PRESENTATION:
Save to your desktop under a folder called “EXCEL”

3. Overview Working with GSS, related crime and Census data
Descriptive statistics 101 – Bring it home!!!
Introducing Excel as your data transformer
Elements of an Excel transformation
Reference questions
Crime and victimization profiles (any topic*)
*Could include industry / economic profiles
Population profiles (GSS today, and touching on the Census/NHS)
Data linking – neighbourhood, population effects on outcomes
Practice exercises for descriptive statistics: Extract, organize, manipulate, present (and archive) data
Joining new variables at the community level
Pros and cons of multiple worksheets
More Excel magic … macros, pivot tables, colectica, preserve Excel for data sharing,
Quantitative human data is very likely to include qualitative data. Often self reported.
Quantitative analysis has two aspects: Descriptive statistics (Description or summarization of or showing the data at hand),
E.g., According to the data from the 2006 Census, women are twice than men as likely to be single parents than men if they live in Ontario. Inferential analysis is about predictions.

4. Learning outcomes
Practice using Excel for your Beyond 20/20, Odesi and other STC outputs – Excel is more than cross-tabulations and pie-charts!
Learn how to do basic data transformations for presentations, ouputing or visualisations
Learn how researchers study neighbourhood/social effect (data joinining with Excel)
Awareness of and best practices for data labeling
Capture your files and work
–for working effectively and being able to back up your research results

5. Introducing Excel Benefits of Excel? Universality
Most students have Excel. (Note: latest version supports over a million rows)
Some professors support it
Many Excel add-ons: like Haver, colectica, and even other people’s Excel macro workbooks
Many Excel tutorials and fairly intuitive!
Excel supports labels, portable/open output file formats, many others, like .dbf for GIS!!!
Go further with GitHub, macros (and shareable NEW macro workbooks.xlsm see [LINK] tricky – archive your visual basic instead), and/or, colectica for best research practices
Excel preserves data labels
Exploit good and well-labeled data!!! WE ARE DOING THIS … !!
SPSS = graphical – pull-down menus
+ syntax code to re-run … you and your supervisor or instructor or readers of your research articles can re-run your statistics
Research replication
Non-SPSS file formats ? Conversion options Can you import or transfer to SPSS .sav ?
SPSS supports some « codebook information »
Non-SPSS file formats? Conversion! Check to see if the original file has data labels?
Note that .sav is a standard SPSS data file. .por is a portable SPSS file
Labels are essential for your descriptive statistics which is partly about showing your statistics, either through statistical tables or in graphs!

6. OUR Research question # 1:
Have property crime rates increased relative to violent crime in Ottawa in the past 15 years?

7. Crime tables … Uniform crime survey
CANSIM
Extract to B20/20
Crime statistics, by detailed offences, annual (Number) *Terminated*, 1977 to Description | StatCan page [LINK]
Incident-based crime statistics, by detailed violations and police services, Ontario, annual (Number), to 2015 Description | StatCan page [LINK]
There is also an archived version on Odesi.
Notes:
Citation on the StatCan page
documentation (remember File  Summary)
Useful to look at these detailed versions
to see what detailed crimes fall under
property crime and violent crime, and
which are excluded.
These tables always break down 
We will only take the Rate per 10000
population
Follow Download tab in CANSIM
Extract as per question (I added Kingston) and save B2020 original, extract and Excel extract
This is B2020’s default chart:

8. HANDS-ON
Download and save Excel CANSIM table extract xls [LINK]
Prepare your columns and rows for graphing: One header row only, one header column (years) followed by data
Start Line Graph
Modify your Line Graph with a chart title, axis labels and grid lines,

9. Let’s create a line graph
Delete rows 2 and 5
Copy and paste to row 21: Rate per 100,000 population
Delete row 1
Create one header row, e.g.:
Do you have only one header row, then data? Good.
Select A1-C17
Do a line graph: Click on Insert 
Under Chart Tools to top right, you will see the Design tab is activated
Click on Add Chart Element on far left and add axis titles and chart titles. You may want to change styles as well.
You can do other things. You can graph year of year change, calculate 15 year change, (see [LINK], graph recession lines
Annual

10. OUR Research question 2:
Does getting older have a positive correlation on the perception that the local police treat people fairly for all Canadians born in Canada versus visible minorities born outside Canada?

11. HANDS-ON (VERY QUICK)
Open Beyond 20/20 CANSIM table extract xls [LINK]
Prepare your data to be GIS ready
Move Geography to rows and change label to geocode

12. Crime / Victimization data … Extract statistics from Odesi
Public-use microdata file
Create custom tabulation in Odesi
Statistics Canada. (2016). General social survey (GSS), 2013, cycle 28, Victimization - Safety [Public use microdata file]. Ottawa, Ontario: Statistics Canada [producer], Ottawa, Ontario: Data Liberation Initiative, Statistics Canada [distributor]. Retrieved from
Why might RTRA be even more interesting for our question?
Follow Download tab in CANSIM
Extract as per question (I added Kingston) and save B2020 original, extract and Excel extract
This is B2020’s default chart:

13. Hands-on Do a bar graph of your percentage table &
Open Odesi Excel table [LINK]
In the yellow highlighted columns …
Calculate Percentages (note, you will first need to total all repondents born in Canada
Do a bar graph of your percentage table &
Insert your frequencies as labels

14. DATA MANIPULATIONS THROUGH CALCULATIONS
Start by downloading an Odesi tabulation with raw numbers
Create Bar graphs to show the relationship between two categorical variables
We will first do our re-code here for all respondents born in Canada using the “sum”  feature for columns B and E
Then we will calculate percentages in the yellow highlighted columns, as =X job/total
Copy and paste special percentages (values only) to green area
Insert the total population size in the labels in red
Do a bar graph

15. HANDS-ON (VERY QUICK)
Open Excel file with postal code related data [LINK]
As time permits, open a new worksheet and do the following join

16. Table join for social / neighbourhood effect research

17. Where to start with Data? REverse of Data Lifecycle

18. Ease, speed and functionality of the applications
Managing your data for multiple applications
Strong data viewer
Visualization potential, e.g., mapping and many more
Retain full wording of variables
Organize your data for great tables and charts!
Intended for about numbers or less (and with short labels)
