7.FUNCTION AS A WEIGHT CHECKER
55
Ex.1) When data is dispersed
Arithmetic = 12.29
Removal = 12.28
The average is calculated by using six samples with the removal of the data of group
⑧
and group
①
.
Ex.2) When the data is biased up or down
Arithmetic = 12.14
Removal = 12.14
If the data of group
⑧
and group
①
are removed, there is no data; therefore the average of all the
data is taken.
Ex.3) When few data available to removal
Arithmetic = 12.14
Removal = 12.11
If the data of group
⑧
and group
①
are removed, only piece of data remains, and the average is
calculated by using the one piece of data.
