Which of these is NOT true for systematic errors?
They arise due to errors in the measuring instruments used.
Repeating the observations or increasing the sample size can eliminate them
They are reproducible inaccuracies that are consistently in the same direction.
They arise from the design of the study.

- 14. Multiple Choice
Two students A and B measured the diameter of a wire in mm.
Data A: 1.57, 1.58, 1.43, 1.50, 1.42 Average of data A: 1.50
Data B: 1.60, 1.59, 1.59, 1.60, 1.62 Average of data B: 1.60
Actual diameter is known to be 1.50 mm.
Whose data is more precise?
A, because the values in his data are close to each other
B, because the values in his data are close to each other
A, because the average value is close to the actual value
B, because the average value is close to the actual value
