 # Add Rolling Average Functionality To Collections
 
 This package adds a rolling average functionality to Laravel's `Collection` facade. Rolling averages (also known as moving averages) are a statistic to capture the average change in a data range over time. For example, looking at a graph of daily temperature, or stock market movement, the graph may appear very noisy and erratic. The graph can be smoothed out to show longer-term trends by replacing each daily data point with an average of the previous N days.
