#### Des de la barra de menús:

Choose Data - Statistics - Moving Average

#### Des de la interfície en pestanyes:

Choose Data - Statistics - Moving Average.

On the Data menu of the Data tab, choose Statistics - Moving Average.

### Dades

Interval d'entrada: la referència de l'interval de les dades a analitzar.

Results to: The reference of the top left cell of the range where the results will be displayed.

## Redueix l'interval d'entrada al contingut de dades real

Check this box to allow trimming of the input range to the actual data content before computing moving-average. Trimming data ignores unused or empty cells after the last non-empty cell in the input range, thus reducing the computing load of the moving average to the actual data. This checkbox is enabled by default.

#### Agrupat per

Select whether the input data has columns or rows layout.

## Paràmetres

Interval: The number of samples used in the moving average calculation.

#### Exemple

The following table has two time series, one representing an impulse function at time t=0 and the other an impulse function at time t=2.
