MOVINGAVERAGE() calculates the expected value, over a past period of fixed length at any time.
Description
MOVINGAVERAGE(Array, PeriodInterval, NewTableFlag)
- Moving average is a calculation to analyze data points by creating a series of averages of different subsets of the full data set.
- Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle Array} can be any positive integers including zero '0'.
- e.g. If Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle PeriodInterval} is set to '6', the average of previous 5 points and the current data point is calculated. Moving Average for first '5' data points cannot be calculated due to less number of data points. Hence Moving average for first '5' data points will be null.
- If Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle PeriodInterval} is omitted, Calci assumes it to be 3.
- If Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle PeriodInterval} < 4, Calci returns an #N/A error message.
- If Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle PeriodInterval} > 'Length of Array', Calci returns an #N/A error message.
- Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle NewTableFlag} can be a logical value TRUE or FALSE. If omitted, Calci assumes it to be FALSE.
- If Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle NewTableFlag} is TRUE, the result is displayed on new zspace sheet.

Examples
Consider the following table with Columns A as data point and Column B as array input for MOVINGAVERAGE() function.
| Period | Array Input | |
| 0 | 0 | |
| 1 | 45.5 | |
| 2 | 60 | |
| 3 | 200 | |
| 4 | 160 | |
| 5 | 300 | |
| 6 | 340 | |
| 7 | 310 | |
| 8 | 500 | |
| 9 | 566 | |
| 10 | 610 |
=MOVINGAVERAGE(A1:A11, 6, TRUE) returns the following table:
| Input | Moving Average |
|---|---|
| 0 | null |
| 45.5 | null |
| 60 | null |
| 200 | null |
| 160 | null |
| 300 | 127.58333333333333 |
| 340 | 184.25 |
| 310 | 228.33333333333334 |
| 500 | 301.6666666666667 |
| 566 | 362.6666666666667 |
| 610 | 437.6666666666667 |
