Dispersion
To calculate the standard deviation of a data set:
stddev(x);
If you already know the mean m, you can make calculations faster with:
stddev(x,m);
Other functions to measure dispersion are:
| Function | Description |
|---|---|
var(x) | Variance |
stddev(x) | Standard Deviation |
min(x) | Minimum Value |
max(x) | Maximum Value |
bounds(x) | Minimum and Maximum Values |
percentile(x,p) | Calculate p-th percentile |
