Question

Four students found the mean of the data set 26, 31, 39, 30, 16, 16, 18, 38. Which student found the correct mean?

Ashrita’s work:
StartFraction 26 + 31 + 39 + 30 + 16 + 16 + 18 + 38 Over 8 EndFraction = StartFraction 214 Over 8 EndFraction = 26.75
Collette’s work:
StartFraction 26 + 38 Over 2 EndFraction = StartFraction 64 Over 2 EndFraction = 32
Daniel’s work:
StartFraction 26 + 31 + 39 + 30 + 18 + 38 Over 7 EndFraction = StartFraction 198 Over 7 EndFraction = 28.29
Lora’s work:
StartFraction 30 + 16 Over 2 EndFraction = StartFraction 46 Over 2 EndFraction = 23
