psychologist studied three computer keyboard designs

psychologist studied three computer keyboard designs. Three samples of individuals were given material to type on an particular keyboard and the number of errors committed by each subject was recorded. The data are as follows:
keyboard A: 0,4,0,1,0
keyboard B: 6,8,5,4,2
Keyboard C: 6,5,9,4,6
Does typing performance differ significantly among the three types of keyboards?
