each group the task of measuring the temperature of a
given object three times. The teacher already knows that
the temperature of the object is 31°C.
Based on each group's results, which group makes the most precise
measurements of the object's temperature?
A. Group A: 31.0°C, 32.0°C, 30.0°C
B. Group B: 29.5°C, 33.0°C, 31.8°C
C. Group C: 32.1°C, 31.9°C, 31.8°C

The group that makes the most precise measurements of the object's temperature is Group C : 32.1°C, 31.9°C, 31.8°C. That is option C.

What is a precise measurement?

Precise measurement are those values that are gotten during a measurement which when compared are closest to the given constant value.

Precision refers to a value in decimal numbers after the whole number, and it does not relate with accuracy.

From the measurement gotten from the different groups, the results that are precise are the results of group C.

This is so because,

  • 32.1-31 = 1.1

  • 31.9-31 = 0.9

  • 31.8- 31 = 0.8

All the values gotten are in decimals as stated above. Therefore, the group that makes the most precise measurements of the object's temperature is Group C.
