When we talk about performance analysis, there are three main ways to collect data: observation, video analysis, and wearable technology. Let’s take a closer look at each one.

1. Observation:

   • This method is about watching and noting how someone performs a skill.
   • It has a pretty good accuracy rate of around 70%.
   • However, one challenge is that personal opinions can sometimes change the results.

2. Video Analysis:

   • This method uses videos to study movement patterns.
   • It’s even more precise, giving us about 80% accuracy.
   • Plus, it allows us to break down performances and look at them in detail.

3. Wearable Technology:

   • This cool tech can track up to 100 pieces of information every second!
   • It has a high reliability rate of about 90% when it comes to collecting body data.

Each of these methods helps us understand performance in different ways. But, wearable technology stands out because it gives us accurate data in real-time.
