# Data Statistics in Calc

Använd datastistik i Calc för att utföra komplex datanalys

Om du arbetar med komplex statistik- eller utvecklingsanalys kan du spara in moment och tid genom att använda Datastatistiken i Calc. Du stoppar in data och parametrar för varje analys och de olika verktygen använder lämpliga statistik- och utvecklingsfunktioner för att beräkna och visa resultaten i en utmatningstabell.

## Stickprov

Skapa en tabell vars data är stickprov från en annan tabell

Så här använder du det här kommandot...

Choose Data - Statistics - Sampling

Stickprov ger dig möjlighet att plocka data från en källtabell för att fylla en måltabell. Stickprov kan vara slumpvis eller periodisk.

Stickprovet görs radvis. Det betyder att stickprovet hämtar en hel rad i källtabellen och kopierar den till en rad i måltabellen.

### Data

Input Range: The reference of the range of the data to analyze.

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

### Stickprovsmetod

Slumpvis: Plockar slumpvis exakt Stickprovsstorlek rader från källtabellen.

Stickprovsstorlek: Antal rader valda från källtabellen.

Periodisk: Väljer rader med ett intervall bestämt av Period.

Period: the number of lines to skip periodically when sampling.

### Exempel

The following data will be used as example of source data table for sampling:

| A | B | C
1 | 11 | 21 | 31
2 | 12 | 22 | 32
3 | 13 | 23 | 33
4 | 14 | 24 | 34
5 | 15 | 25 | 35
6 | 16 | 26 | 36
7 | 17 | 27 | 37
8 | 18 | 28 | 38
9 | 19 | 29 | 39

Sampling with a period of 2 will result in the following table:

12 | 22 | 32
14 | 24 | 34
16 | 26 | 36
18 | 28 | 38
