Suppose a biologist studying the mechanical limitations of growth among different species of tulips monitors a national preserve

. He collects data on the heights of 10 different types of tulips in the reserve and rounds each height to the nearest centimeter.
25,21,26,24,29,33,29,25,19,24

Answer:

Q_1 = 24

Q_3 = 29

IQR= Q_3 -Q_1 = 29-24 =5

Step-by-step explanation:

For this case we have the following dataset:

25,21,26,24,29,33,29,25,19,24

The first step is order the data on increasing order and we got:

19, 21, 24, 24, 25, 25, 26, 29, 29 , 33

For this case we have n=10 an even number of data values.

We can find the median on this case is the average between the 5 and 6 position from the data ordered:

Median = \frac{25+25}{2}=25

In order to find the first quartile we know that the lower half of the data is: {19, 21, 24, 24, 25}, and if we find the middle point for this interval we got 24 so this value would be the first quartile Q_1 = 24

For the upper half of the data we have {25,26,29,29,33} and the middle value for this case is 29 and that represent the third quartile Q_3 = 29

And finally since we have the quartiles we can find the interquartile rang with the following formula:

IQR= Q_3 -Q_1 = 29-24 =5
