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 is defined as the difference of highest and lowest value in the data
Range = Highest value − Lowest value
= (146 − 125) cm
= 21 cm
