Answer :
The interquartile range (IQR), calculated as the difference between the third quartile (Q3) and the first quartile (Q1), provides a measure of the spread in the middle 50% of the data. In this case, the IQR is 98 units.
Interpretation of quartiles: The quartiles are the values that split a dataset into four equal parts. The first quartile (Q1) splits the bottom 25% of the data from the rest. The second quartile (Q2) splits the data set in half, while the third quartile (Q3) splits the top 25% from the rest.
Given, Q1 = 74, Q2 = 111, and Q3 = 172.
We need to interpret the quartiles.
According to the given values, 25% of the samples contain less than 74 units.25% of the samples contain between 74 and 111 units. 25% of the samples contain between 111 and 172 units.25% of the samples contain greater than 172 units. Thus, the correct option is V. The quartiles suggest that 25% of the samples contain less than 74 units, 25% contain between 74 and 111 units, 25% contain between 111 and 172 units, and 25% contain greater than 172 units. (Option V).
Determination of IQR: The interquartile range (IQR) is the range of the middle 50% of the data set. The IQR is calculated as follows:IQR = Q3 − Q1IQR = 172 − 74 = 98Thus, the value of IQR is 98.
Hence, the Main Answer is IQR = 98. The Explanation is: The interquartile range (IQR) is the range of the middle 50% of the data set. The IQR is calculated as follows: IQR = Q3 − Q1. Thus, IQR = 172 − 74 = 98 units.
The Solution is 1QR = 98. Thus, the interquartile range (IQR) is 98.
