Introduction
============

[](#introduction)

Talking about data, we also talk about statistics because we learn about data through statistics. The `Statistics` package allows you to compute basic and advanced statistical measures for columns of your data. The basic measures could be `min`, `max`, `mean`, `median`, etc. The advanced measures are, for example, `lowerQuartile`, `popStdDeviation` and others.

Installation
============

[](#installation)

### By downloading .zip file

[](#by-downloading-zip-file)

1. [Download](https://www.koolreport.com/packages/statistics)
2. Unzip the zip file
3. Copy the folder `statistics` into `koolreport` folder so that look like below

├── core
├── statistics
```

### By composer

```

Documentation
=============

[](#documentation)

Quick start
-----------

[](#quick-start)

In your report's setup page, use the process `\koolreport\statistics\Statistics` with an array parameter in the type of '{{statistical measure}}' => '{{array of column names}}'

```

```

Properties
----------

[](#properties)

The package supports the following statistical measures:

namedescription`min`Returns the first minimum value of a data series.`max`Returns the first maximum value of a data series.`mode`Returns the first most common value of a data series.`mean`Returns the average value of a data series.`median`Returns the middle value that divides a data series into 2 equal halves when ordering.`lowerQuartile`Returns the first quartile of the quartiles that divides a data series into 4 equal group when ordering. The second quartile is the median.`upperQuartile`Returns the third quartile.`percentile_X`Returns the value that X percentage of a data series fall below when ordering. X is an integer from 0 to 100.`meanDeviation`Returns the mean absolute deviation value of a data series in the formula of Sum of absolute(elementValue - mean) / length of data series.`popStdDeviation`Returns the population standard deviation value of a data series in the formula of Square root of (sum of square(elementValue - mean) / length of data series).`samStdDeviation`Returns the sample standard deviation value of a data series in the formula of Square root of (sum of square(elementValue - mean) / (length of data series - 1)).Support
