The first colorimeter is precise, but it is not accurate. It seems to have a zero error of -5.
We can conclude its precision because the readings are closely grouped, but its lack of accuracy is due to its variation from the actual value. Moreover, the variation is consistently of 5 points lower than the actual value, so its zero error may be -5.
The second colorimeter may be referred to as being accurate.
