University - STANDARD DEVIATION (SD) Standard deviation measures how spread out the data are around the mean (average). It shows the typical distance of observations from the mean. WHAT SD TELLS US: • Small SD → values are close to the mean. • Large SD → values are widely dispersed. • SD = 0 → all observations are identical. • SD is expressed in the same units as the original data. • SD alone does NOT tell you whether data are normally distributed. EXAMPLE: Two groups can have the same mean but different SDs. Group A: Mean = 70, SD = 3.2 → values are close to 70. Group B: Mean = 70, SD = 12.8 → values are more widely spread. COMMON MISCONCEPTIONS: ❌ SD is not the same as the mean. ❌ A larger SD does not mean the mean is larger. ❌ SD does not tell you the shape of the distribution. ❌ SD is not the same as variance. Variance = SD² TAKEAWAY: Standard deviation tells you how much the data vary or spread around the mean. It is a key measure of variability in research and data analysis. | Facebook
