a. what quarter has the smallest spread of data?\nsecond\nfirst\nthird\nfourth\nb. what is that spread?\ni\nc. what quarter has the largest spread of data?\nfirst\nthird\nsecond\nfourth\nd. what is that spread?\ne. find the inter quartile range (iqr):\nf. which interval has the most data in it?\n30 - 36\n36 - 42\n42 - 100\n26 - 29
Answer
Explanation:
Step1: Identify quartile ranges
First - from 24 to 27, spread is (27 - 24=3). Second - from 27 to 29, spread is (29 - 27 = 2). Third - from 29 to 36, spread is (36 - 29=7). Fourth - from 36 to 42, spread is (42 - 36 = 6).
Step2: Answer part a
The second quartile has the smallest spread.
Step3: Answer part b
The spread of the second quartile is 2.
Step4: Answer part c
The third quartile has the largest spread.
Step5: Answer part d
The spread of the third quartile is 7.
Step6: Calculate IQR
IQR = Third - First quartile. First quartile value is 27, third quartile value is 36. So (IQR=36 - 27=9).
Step7: Answer part f
The box - and - whisker plot shows that the middle 50% of the data (from 27 to 36) has the most data. The interval (30 - 36) is part of this middle 50% range.
Answer:
a. Second b. 2 c. Third d. 7 e. 9 f. 30 - 36
