Correct Answer: Option D
Explanation:
0.4, −0.4, 0.3, 0.47, −0.53, 0.2, −0.2
Range is the difference between the highest and lowest value
i.e Highest − Lowest
− 0.53, −0.4, −0.2, 0.2, 0.3, 0.4, 0.47
0.47 is the highest
− 0.53 is the lowest
− = 0.47 − (− 0.53)
−0.47 + 0.53
= 1.0
0.4, −0.4, 0.3, 0.47, −0.53, 0.2, −0.2
Range is the difference between the highest and lowest value

− 0.53, −0.4, −0.2, 0.2, 0.3, 0.4, 0.47
0.47 is the highest
− 0.53 is the lowest
− = 0.47 − (− 0.53)
−0.47 + 0.53
= 1.0
