Normal Bell Curve The standard deviation of a test score can be a helpful measure when determining if occupational therapy services are needed. OTs typically use the standard deviation as a determining factor when deciding whether a child’s test score is sufficiently below the mean to warrant occupational therapy services. One SD from the average or standard score isn’t statistically significant.

Struggling with standard deviation? 🤔 📊 WHAT IS SD? 👉 Measure of data spread 📈 SIMPLE IDEA ✔ Low SD → Data close to mean ✔ High SD → Data spread out 📊 EXAMPLE Data A: 10, 11, 12 → Low SD Data B: 5, 10, 20 → High SD 📊 Low SD → Data is close 📈 High SD → Data is spread 🔻 WHY IMPORTANT? 👉 Shows variability of Data 👉 Helps compare datasets
