1. Badminton Data Collection

2. Identify your performance strengths and weaknesses.
Why do you need to gather information on your badminton performance?
Identify your performance strengths and weaknesses.
Prioritise a weakness and form a Specific Training Programme.
Select appropriate methods of practice to improve your identified weakness – Related to your Stage of Learning
Identify how well you performed in defence and attack
Identify areas of the court not covered well
Identify times when your level of performance in the game was low. Reflect on this.
Provides a permanent record for you to compare future performances. (own/peers)
Measure improvements

3. How do we gather information?
We must consider what data we want to collect and then select an appropriate tool of analysis for obtaining this data. Data must be relevant
Initial Data: Whole performance – Match Analysis
Focused Data: Isolate/prioritise a weakness and look more closely at this weakness to obtain more detailed data

4. Methods of collecting data
There are several tools of analysis we can use to obtain information on our performance
Initial Data: General observation schedules
Match Analysis sheets, (Video), Scattergrams
Focused Data: Focused observation schedules – Movement Analysis Sheets (Video) Scattergrams

5. General Observation Schedule – Badminton
Perform a 5 minute of badminton singles against an opponent of similar ability.
Ask an observer to read the criteria for success overleaf for each of the skills performed below and place a tally mark in the appropriate box to identify if the skill was performed successfully or unsuccessfully.
Name of Performer: Name of Opponent:
Name of Observer:
Skill/ Technique
Successful
Unsuccessful
High Serve
Low Serve
Overhead Clear
Drop Shot
Smash
Net Shot

6. High Serve OHC Drop Shot Smash Net Shot Underarm Clear Backhand
CRITERIA FOR SUCCESSFUL PERFORMANCE OF SKILLS/TECHNIQUES PERFORMED IN BADMINTON
Low Serve
Shuttle flies low over the net and lands just over the service line
High Serve
Shuttle flies high through the air and lands between tram lines at the back of the court
OHC
Shuttle is hit high above and in front of head. Shuttle flies high through the air and lands between the tram lines at the back of the court
Drop Shot
Shuttle is hit high above and in front of head. Shuttles flies high through the air and drops sharply to the ground just over the net
Smash
Shuttle is hit high above and in front of the head. Shuttle is hit with great force and travels quickly in a straight line, sharp angle, to the floor of the opponents’ court
Net Shot
Shuttle is contacted at net height and skims over the net to land in front of opponent’s court
Underarm Clear
Shuttle is contacted underarm and is cleared to opponents’ court
Backhand
Any backhand attempted goes over the net to opponent’s court played away from opponent

7. Feedback – Information we receive about our performance
Feedback can be received in different ways
External: Visual/verbal/written
Internal: Kinaesthetic (feeling)

8. External
Verbal
Visual
Written

9. Feedback/ Data
The feedback you obtain will be
Quantitative: Knowledge of Results
i.e. 7/10 OHC were successful
Qualitative: Knowledge of Performance
i.e. I successfully contacted the shuttle above my head with a straight arm

10. Validity and Reliability
Data collected must be valid and reliable
Valid: Data obtained is relevant
Appropriate tool of analysis used.
Free from human error
Reliable: Data must be accurate
Non bias
Objective data is more accurate than subjective.

11. Practical ways of obtaining valid and reliable data
Invalid or unreliable information occurs when too much information is trying to be gathered at once and human error accounts for mistakes in the data. Ways to prevent this from happening are:
Use video in conjunction with your Analysis Method. You can rewind and pause performance situations so that no information is missed. Totally free from human error!
Use more than one observer who has previous knowledge of badminton i.e. MP or teacher.
When gaining qualitative data (subjective), try and obtain quantitative data at the same time to provide you with more reliable information.

12. Remember!
When re-testing your performance you must test under the exact same conditions. Test parameters must be identical. This will ensure all data obtained is valid and reliable and will allow you to make COMPARISONS!
