The interquartile range (IQR) is the range of values within which reside the middle 50 of the scores The lower boundof the interquartile range is called the first quartile (Q1) -- 25 of the scores have a value lower than Q1 and 75 of the scoreshave a value larger than Q1
The Inter-Quartile range is calculated: IQR = Q3 – Q1 The size of the IQR indicates how spread out the middle half of the data is Outliers (1 5 x IQR Rule) Now that we have a measure of spread we can use it to identify values that are much farther from the center than usual How?
The interquartile range (IQR) is essentially the middle 50 of the data set IQR = Q3- Q1 Using the applicant data the IQR is: IQR = 75 - 46 = 29 Z -Scores qZ -score determines the relative position of any particular data value x and is based on the mean and standard deviation of the data set

How to calculate interquartile range?
The Inter-Quartile range is calculated: IQR = Q3 – Q1 The size of the IQR indicates how spread out the middle half of the data is. Outliers (1.5 x IQR Rule)
What is the lower bound of the interquartile range?
The lower boundof the interquartile range is called the first quartile (Q1) -- 25% of the scores have a value lower than Q1 and 75% of the scoreshave a value larger than Q1. The upper bound of the interquartile range is called the third quartile (Q3) -- 75% of the scores have avalue lower than Q3 and 25% of the scores have a value larger than Q3.
Is IQR a range or a value?
Consider the data in the example. Q1 (17) is muchcloser to the median (21.5) than is Q3 (32), however this is not conveyed by reporting that IQR = 15. For this reason, it ismore useful to report the IQR as a range (reporting Q1 and Q3), rather than as a value. The 12 stores in this sample displayed a Mdn of 21.5 fish (IQR = 17-32).
What is a quartile score?
Interquartile Range Z -Scores 1 Quartiles Quartiles are merely particular percentiles that divide the data into quarters, namely: Q1= 1st quartile = 25th percentile (P25) Q2= 2nd quartile = 50th percentile = median (P50) Q3= 3rd quartile = 75th percentile (P75)
