Understanding Moving Average

The Moving Average is a simple yet powerful technique used to smooth out time series data, reducing noise and highlighting underlying trends. It works by averaging data points over a specified window size.

For example, a 3-point moving average calculates each new point as the average of the current point and the two preceding points. This helps to smooth out short-term fluctuations, making it easier to see longer-term patterns in the data.

To use this calculator, simply input your time series data as comma-separated values and choose a window size. The tool will then calculate and display the smoothed data, along with an interactive chart for visualization. Use a smaller window size for less smoothing and a larger window size for more significant smoothing.
