Mathematics Question on Arithmetic Mean
Find the range of heights of any ten students of your class.
Answer
Let the heights (in cm) of 10 students of our class be 125, 127, 132, 133, 134, 136,138, 141, 144, 146 Highest value among these observations = 146
Lowest value among these observations = 125
Range = Highest value - Lowest value = (146 - 125) cm = 21 cm
