Remove Anomalies in a Ruby Array
When working with large data sets, you’ll discover that there are many times where your collections have anomalies that need to be removed. In this guide we’ll walk through how to easily remove any values lower or higher than a range of values.

Standard Heredoc Example
[44, 8043, 443, 43452, 2183].remove_anomalies 100, 10_000 # => [8043, 443, 2183]
Real World Usage
When working with machine learning algorithms, one of the key requirements is to clean up the data and remove anomalies. Imagine a situation where you are building a baseball statistic algorithm and you want to ignore players who only played in a few games to ensure that you are only looking at data from a typical player. In this guide, we focused on how to leverage a helpful Ruby method that allows you to quickly return only the data that you need.
