Find the IQR of the data set: 2, 4, 5, 6, 8, 9, 13, 14, 15, 18.
a 8
b 16
c 9
d 11
YOU GOT ME A 20
here are the right answers
1.9
2.17
3.4
4. David had a higher variability because his IQR is 8 more than Gabby's
5.The IQR for both sets of 8
Please trust me!!! If you agree then please say "CATS" Thank you :)
find Q1 and Q3 as usual
The IQR is Q3 - Q1
Pls help
IF YOUR RIGHT YoTeacherlsMeFools Then Okay I will see.
If not then I will give the right answers

To find the Interquartile Range (IQR) of a data set, you need to follow these steps:
Step 1: Arrange the data in ascending order.
The given data set: 2, 4, 5, 6, 8, 9, 13, 14, 15, 18.
Step 2: Find the median (second quartile or Q2) of the data set.
Since the data set has an even number of values, the median is the average of the two middle values. In this case, (8 + 9) / 2 = 8.5.
Step 3: Find the first quartile (Q1).
To find the first quartile, you need to find the median of the lower half of the data set. Since the lower half is 2, 4, 5, 6, and 8, the median is (4 + 5) / 2 = 4.5.
Step 4: Find the third quartile (Q3).
To find the third quartile, you need to find the median of the upper half of the data set. Since the upper half is 9, 13, 14, 15, and 18, the median is (13 + 14) / 2 = 13.5.
Step 5: Calculate the IQR.
The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). In this case, 13.5 - 4.5 = 9.
Therefore, the IQR of the given data set is 9. Hence, the correct answer is option c) 9.
