Answer:
3.59
Step-by-step explanation:
We know the formula: Qi =
First Quartile: Q1 = = (1 * 161)/4 = 40.25 th value.
Since it will be in the interval (10 - 20), therefore, group of Q1 = (10 - 20)
Q1 = = 14.80.
Third quartile will be:
Q3 = value
120.75th value is in the interval (30 - 40).
Therefore, group for Q3 = (30 - 40).
Q3 = = 11.21
Quartile deviation = = 3.59
