Two clocks are being tested against a standard clock located in a national laboratory.At 12:00:00 noon by the standard clock,the readings of the two clocks are Day 1 Day 2 Day 3 Day 4 Day 5 CLOCK 1 12:00:04 12:02:19 12:01:50 11:59:04 11:59:08 CLOCK 2 11:15:24 11:15:01 11:14:59 11:15:00 11:14:28 Which of the two clocks will you prefer to measure the time intervals during an experiment? Pls Explain with reasons.

The range of variation over the five days of observation is 166s for clock 1 & 32 s for clock 2.The average reading of clock is 1 is much closer to the standard time than the average reading of clock 2.But a clock zero error is not as significant for precision work as its variation,because a zero-error can always be easily corrected.Hence,clock 2 is preferred .

Answer: The range of variation for clock 1 is 162s. And that for clock 2 is 31s .
Therefore clock 2 is right answer..
