The error formula:

Deviation = |mean-value|

Avg. Devation= sum of devations divided by # of trials

%error = avg. devation over mean multiplied by 100

 

Surface:

Mean = (20.23+ 22.93+ 19.51)/3= 20.89

Trial 1- |(20.23-20.89)|= 0.66

Trial 2- |(22.93-20.89)|= 2.04

Trial 3- |(19.51-20.89)|= 1.38

(0.66+ 2.04+ 1.38)/3= 1.36

1.36/20.89= .065 (7% rounded)

*we calculated each data table using this method

*fps formula is the data divided by 20
