Use the moving average tool to calculate moving averages of the data set. A moving average provides useful trend information of the data that is lost in a simple average. In addition, moving averages can be used to eliminate random variance. For example, use this tool to create a smoother curve of a stock prize.
To use this tool, first specify the cells containing the values whose moving averages you want to calculate in the "Input Range" entry. Then specify the "Interval" for the moving average. The interval specifies the number of values to be included in the moving average.
The results are given in a column. Each row represents the moving average for the corresponding row in the input range. The moving average cannot be calculated for the first "k" rows in the input range where "k" is smaller than the given interval.
