What is a judged (scored) sport?
In a judged sport the winner is not decided by a clock or a tape. People called judges watch the performance and give marks. Examples: gymnastics, diving, figure skating, artistic swimming and dance sport. Compare this with measured sports like running, where time or distance decides.
How scores are made: D and E
Rules differ by sport, so always read the rules of your sport. One common way is:
- D score: how difficult are the skills? More and harder skills give a higher D.
- E score: how well were they done? Judges start from a top mark and take away for errors such as a wobble or a bent knee.
Total = D + E. Example: 5.2 + 8.4 = 13.6.
Five ways to take part
- Perform: do the routine.
- Judge: learn the rules and score fairly.
- Coach: help others improve and choose safe routines.
- Watch with understanding: know what the judges look for.
- Organise: arrange the event, timing, scorecards and safety.
Each way teaches you what a good performance looks like.
Fair judging: dropping the highest and lowest
Judges are human. To keep it fair, many events use several judges, drop the highest and lowest marks and average the rest. This is a trimmed average. Example marks: 8.2, 8.6, 8.7, 9.4, 8.5. Drop 8.2 and 9.4. Average of 8.6, 8.7, 8.5 is 25.8 ÷ 3 = 8.6. Judges must be honest, calm, and give reasons from the rules, not from liking a player.
Composing a routine and staying safe
A routine is a plan. Choose skills you can do cleanly, start strongly, link moves smoothly and finish clean. Adding a harder skill raises D, but if it makes you make errors, E falls. So the best routine is often the one you can do well, not the hardest. Warm up, use safe equipment and practise a new skill with a coach before showing it.
Try it: judge a short routine
Ask a friend to do a five-move balance routine. With two others, each give a mark out of 10 for how clean it was. Drop the highest and lowest and average the rest. Talk about why each of you gave your mark.
Key formulas and definitions
- Total score = D + E
- Trimmed average = (sum of marks − highest − lowest) ÷ (number of marks − 2)
- Key term: D = difficulty score
- Key term: E = execution score (how clean)
Worked examples
1. A gymnast has D = 5.0 and E = 8.5. What is the total?
Total = D + E = 5.0 + 8.5 = 13.5.
2. Five judges give 7.8, 8.0, 8.2, 8.4, 9.0. Find the trimmed average.
Drop lowest 7.8 and highest 9.0. Left: 8.0, 8.2, 8.4. Sum = 24.6. Average = 24.6 ÷ 3 = 8.2.
3. Aman adds a harder jump. D rises from 4.0 to 5.0 but E falls from 9.0 to 7.8. Was it worth it?
Before: 4.0 + 9.0 = 13.0. After: 5.0 + 7.8 = 12.8. The total fell, so the harder jump was not worth it for now. He should practise it more.
Common mistakes
- Thinking the hardest routine always wins. Errors lower E.
- Judging by who you like instead of the rules.
- Forgetting to drop both the highest and the lowest marks in a trimmed average.
- Doing a new risky skill with no coach and no warm-up.
