About
A rolling (or moving) average smooths out noise so the trend is easier to see. Each point is the average of the last few values, so a 3-point rolling average at week 10 is the mean of weeks 8, 9 and 10. The line starts once there are enough values to fill the first window.
It’s handy for sprint throughput, cycle times, weekly sales or anything else that bounces around. A wider window gives a smoother line that reacts more slowly to change. The dashed line shows the overall average for comparison.

Questions
What window size should I use?
Start with 3 to 5 for weekly or sprint data. Use a wider window if the line is still jumpy, or a narrower one if it hides real changes.
