1. Raw data required / data sources
SSP4000 Research Process
Week 19 (SPA-specific)
Raw data required / data sources

2. Learning Outcomes By the end of this session you will be able to
Describe the raw data required to answer your research question
Describe the methods of data capture / data gathering to be used

3. Example – RED CARD STUDY
Scope
English FA Premier League
Matches with a single red card before 60 minutes
Matches where the team reduced to 10 men is drawing or winning by a single goal at the time of the dismissal
Question (Level at time of dismissal)
Does work-rate differ between outnumbered teams who avoid losing and those who lose?
What about the opposition?
Question (Leading by a goal at time of dismissal)
Does work-rate differ between outnumbered teams who hold on to their lead and those who don’t?

4. Work-rate variables
Percentage of time spent performing high speed running (> 5.5 m.s-1)
Number of high speed runs per minute
We are mainly interested in period when the team was outnumbered
Would be interesting to compare with period prior to the dismissal
There is more than one way of doing this

5. Thinking ahead – results format For each variable
Is there a better way to present this if we are also looking at period before the dismissal
Are we interested in the pre-post-dismissal difference? Might confuse coaches

6. Quantitative Data Analysis
Data Processing
For our example, the Prozone 3 system captures player movement data
These are quality assured by Prozone staff visually verifying frames
Data for individual matches then need to be brought together to determine results for “the average match” – quantitative analysis
PROZONE
Quantitative Data Analysis

7. Data Sources X, Y locations
pitch dimensions 0,0 is centre circle
Distance covered, velocity and acceleration derivatives
Time of red card in each match
We need an understanding of what Prozone3 provides and what we need to produce through data processing

8. Your turn What data are required?
Are they gathered using manual, automated or semi-automated systems?
What equipment are involved?
Do systems need to be calibrated?
Are there operating procedures for systems that need to be described?
Level of players / matches used?

9. Task for next week
Complete a list of raw variables and link each of these to the research study’s dependent variables to be calculated directly or indirectly using them
