Statistics (stats.py)

The Statistics module in NumLex offers a variety of functions for statistical analysis, including calculations for means, medians, modes, var, and standard deviation.

Functions

ungrp_mean(data): Calculates the mean for ungrouped data.
```
mean = ungrp_mean([10, 20, 30, 40, 50])
```
grp_mean(data, frequencies): Calculates the mean for grouped data.
```
mean = grp_mean([10, 20, 30], [2, 3, 5])
```
median(data): Finds the median of a dataset.
```
med = median([10, 20, 30, 40, 50])
```
ungrp_mode(data, frequencies): Determines the mode for ungrouped data.
```
mode = ungrp_mode([10, 20, 20, 30, 40],[2, 3, 5,9])
```
raw_mode(data): Determines the raw mode of data.
```
mode = raw_mode([10, 20, 20, 30, 40])
```
var(data): Calculates the variance of data.
```
variance = var([10, 20, 30, 40, 50])
```
std_dev(data): Calculates the standard deviation of data.
```
std_deviation = std_dev([10, 20, 30, 40, 50])
```
