Question

Which of the following is true of the data set represented by the box plot?

The greatest value in the set is 79.
The data is evenly distributed throughout the middle half.
The data has an IQR of 45.
Removing the outliers would not affect the median.

Answer 1

okay well B isnt right

Answer 2

A is right but i dont think that is the answer they are looking for . what is the lesson on ?

Answer 3

Answer 4

are you learning about IQR or something else?

Answer 5

yes IQR

Answer 7

alright then lets try to find the IQR of this problem because im pretty sure that since thats what the lessons about thats what the answer is going to be about. so do you know how to find IQR?

Answer 8

yes Using a box plot to represent data graphically can often help you to recognize outliers. On a box plot, outliers fall significantly below the first quartile, or significantly above the third quartile. We measure the significance according to the interquartile range (IQR), which is Q3 – Q1, and it is another measure of spread.

An outlier is more than 1.5 times the IQR less than the first quartile, or more than 1.5 times the IQR greater than the third quartile.

Lower Limit: Outlier < Q1 − 1.5(IQR)
Upper Limit: Outlier > Q3 + 1.5(IQR)

Let’s determine if any of Sylvia’s data would be considered an outlier and create a box plot. (Include the owner’s wage in the data.)

data arranged in numerical order, 10 labeled as Q1, 18 labeled as Q2, and 20 labeled as Q3


IQR = Q3 − Q1 = 20 − 10 = 10

Outlier limits:

Q1 − 1.5(IQR)
10 − 1.5(10) = 10 − 15 = -5 Q3 + 1.5(IQR)
20 + 1.5(10) = 15 + 20 = 35

Therefore, any value less than -5 or greater than 35 is an outlier. Since 51 is greater than 35, it is an outlier. We indicate the outlier with a dot, and only draw the whisker to the next greatest value, 22.

Answer 9

okay so can you find the iqr of this problem?

Answer 10

it ranges from 35 to 79

Answer 11

79-35=45

Answer 12

thats the simple way to do it so your answer should be C!

Answer 13

thankz
