What's standard deviation (SD)? ๐
- It's the spread of scores around the mean (average).
- Think of it as a measure of how spread out numbers are.
- Fun Analogy: Imagine you and your friends are trying to hit a target. The SD tells you how far off everyone's shots were!
Golf putting example ๐ฏ
- A learner tries golf putting over 5 lessons, taking 30 test putts after each lesson.
- The coach calculates the average (mean) of the putts.
- To add more context, error bars are used. These:
- Represent the SD from the mean.
- Show variability of the data.
- Are super helpful to see how consistent a golfer is!
Graph insights ๐
- While average might show that two players are on par ๐๏ธโ๏ธ (pun intended!), their SDs might reveal more.
- Example: Saeed vs. Asif
- Both have similar averages in putting.
- However, Saeed's SD is smaller, meaning he's more consistent. Asif's putts vary a lot more.
- Real-world Takeaway: Coach may train them differently based on this insight!
Fun fact โจ
Standard Deviation can be represented by "s", "SD", or the Greek letter sigma (σ).
