Histogram
Gör uppgiften nedan genom att använda Excel eller GeoGebra.
Spara Excel som pdf och ladda upp filen här på wikiskola. Lägg en länk till filen.
Som i bilden till höger kan det se ut.

Statistik i GeoGebra
Det går alldeles utmärkt att göra histogram och annat i GGB.
1, 1, 2, 3, 2, 4, 3, 3, 2, 1, 4, 3, 5, 6, 7, 8, 9, 9, 11, 12, 3, 4
Siffrorna ovan kan man exempelvis klippa in i GGB och sedan klicka analysknappen. Ger automatiskt histogram och standardavvikelse och allt man kan begöära. Vi kan ha det som grund för alla undervisning.
