|---|---|
| Back | - Continuous variation plotted on graph to form normal distribution curve (bell shaped curve), where mena/mode/median are the sme, shape is symmetrical about the mean and most values lie close to mean - SD is measure of spread of data, if characteristic has high SD, variance also high, wen SD calculated of data displaying normal distribution, 68% of values lie 1 SD of mean, 95% within 2 SD of mean and 99.7% within 3 SD of mean |
