Question

Carol wanted to see how the data would change if she did not include the outlier in her study. The results are shown in the table with the outlier crossed out.
Find each listed value.
Range =
Median =
Lower quartile and upper quartile =
Interquartile range =
Which value was affected the most?

Answer 1

Answer:

the range was affected the most

Step-by-step explanation:

• Range  

The biggest watch news is: 46

The smallest watch news is" 26

So the range of the data

26 ≤ range ≤ 46

• Median is the "middle" of a sorted list of numbers

So we will rearrange the list:

26 26 32 35 38 39 40 45 46

So the median is 38

• Lower quartile and upper quartile

As we know the lower quartile value is the median of the lower half of the data. The upper quartile value is the median of the upper half of the data.

So, the lower quartile is: (26+32)/2 = 29

the upper quartile is: (40+45)/2 = 47.5

• Interquartile range

The upper quartile - the lower quartile = 47.5 -29 = 18.5

• Which value was affected the most?

If she does not cross the outlier, our data set is:

26 26 32 35 38 39 40 45 46 72

=> median : (38+39)/2 = 38.5

=> The upper quartile: 45

=> The lower quartile: 32

=> Interquartile range : 45 -32 = 13

=> the range (26 ≤ range ≤ 72)

So the range was affected the most

Answer 2

Answer:

range= 20

median= 38

Lower quartile and upper quartile = 29 and 42.5

Interquartile range = 13.5

Which value was affected the most? range
