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 not b

step-by-step explanation:

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
