Pls
find the range and interquartile range of the data below.
13, 14, 15, 18, 19, 19, 19, 20
question 2 options:
range = 7
iqr = 5
range = 20
iqr = 4
range = 7
iqr = 4.5
range = 13 to 20
iqr = 14.5 to 19

Option c. Range = 7 IQR = 4.5

Step-by-step explanation:

We have to find the range and interquartile range of the data below :

13, 14, 15, 18, 19, 19, 19, 20

Range: The range of set of data is the difference between the highest and the lowest values of the data set.

Range = Highest value - lowest value

Range = 20 - 13 = 7

Interquartile range (IQR): To find the IQR first we find the median of the data set.

13, 14, 15, 18, 19, 19, 19, 20

Median = (18 + 19)/2 = 18.5

= 18.5

Now we calculate the median of first half of the data set to find

13, 14, 15, 18

= (14 + 15)/2 = 14.5

and then calculate the median of second half of the data set to find

19, 19, 19, 20

= (19 + 19)/2 = 19

IQR = -

IQR = 19 - 14.5 = 4.5

Range = 7

IQR = 4.5

its an acute right triangle
