Question 13 3 pts Consider three data series, each a random sample of seven observations (n = 7): Series 1: {1, 1, 1, 3, 5, 5, 5} . Series 2: {1, 1, 3, 3, 3, 5, 5} Series 3: {1, 3, 3, 3, 3, 3, 5} The interquartile range of Series 1 is: 04 ОО 02 O 1 3 pts

Answer 1

Ans. Option a

Median = Middle term of the series = 3

Quartile 1, Q1 = Middle term of the series to the left of median = 1

Quartile 3, Q3 = Middle term of the series to the right of the median = 5

=> Interquartile range = Q3 - Q1 = 5-1 = 4
