Average
Which student's measurements were most precise?
Ken's measurements were most precise because his average measured temperature
was closest to the expected value of 100.0°C
Kamaria's measurements were most precise because his average measured
temperature was closest the expected value of 100.0°C
Autumn's measurements were most precise because they were most similar and only
varied by 0.04 "C.
Kamaria's measurements were most precise because they were most similar and only
varied by 0.2°C
