Whose measurements were the most precise?

Julian's

Mia's

Sonu's

Parul's

Four students measure the length of a minute-long trial four

times. They record their measurements as shown.

Julian:

57.3 seconds, 58.8 seconds, 59.5 seconds, 62.1 seconds

Mia:

58 seconds, 59 seconds, 60 seconds, 61 seconds

Sonu:

50 seconds, 60 seconds, 60 seconds, 70 seconds

Parul:

57.23 seconds, 59.32 seconds, 62.34 seconds, 63.91

Step-by-step explanation:

In finding the most precise measurement of the measurement of a minute long trial by the students, the average of the four experiments need to be calculated and the closest result to a minute (being the threshold) is the most precise.

Mila Sonu Parul

! st trial 57.3 58.8 59.5 62.1

Second trial 58 59 60 61

Third trial 50 60 60 70

Fourth trial 57.23 59.32 62.34 63.91

Total min. 222.53 237.12 241.84 257.01

Average min 55.63 59.28 60.46 64.25.

The most precise result is Mila experiment which is 59.28 being the closest measurement to a minute.
