Il-firxa interkwartili (IQR) hija d-differenza bejn il-kwartili ta 'fuq (Q3) u t'isfel (Q1), u tiddeskrivi l-50% tan-nofs tal-valuri meta ordnati mill-aktar baxx għall-ogħla. L-IQR spiss jitqies bħala a better measure of spread than the range as it is not affected by outliers.
Hereof, How do you interpret Q1 and Q3? Q1 hija l-medjan (in-nofs) tan-nofs t'isfel tad-dejta, and Q3 is the median (the middle) of the upper half of the data. (3, 5, 7, 8, 9), | (11, 15, 16, 20, 21).
How do you interpret a range? Interpreting the Range
Il-firxa hija interpretata bħala l- dispersjoni ġenerali tal-valuri f'sett tad-dejta jew, aktar litteralment, bħala d-differenza bejn l-akbar u l-iżgħar valur f'sett tad-dejta. Il-firxa titkejjel fl-istess unitajiet bħall-varjabbli ta' referenza u, għalhekk, għandha interpretazzjoni diretta bħala tali.
Additionally Why is IQR important? Besides being a less sensitive measure of the spread of a data set, the interquartile range has another important use.

How do you interpret mean and SD? Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out. A standard deviation close to zero indicates that data points are close to the mean, whereas a high or low standard deviation indicates data points are respectively above or below the mean.
What does IQR stand for? The “Interquartile Range” is the difference between smallest value and the largest value of the middle 50% of a set of data.
X'inhi r-regola IQR?
The interquartile range is calculated in much the same way as the range. All you do to find it is subtract the first quartile from the third quartile: IQR=Q3 –Q1. The interquartile range shows how the data is spread about the median.
Also What is the IQR of the data set? The IQR describes in-nofs 50% tal-valuri meta ordnat mill-aktar baxx għall-ogħla. To find the interquartile range (IQR), first find the median (middle value) of the lower and upper half of the data. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.

Bl-istess mod, kurtożi ta' inqas minn –1 tindika distribuzzjoni li hija ċatta wisq.

How do you determine range? The range is calculated by jitnaqqas l-inqas valur mill-ogħla valur. Filwaqt li firxa kbira tfisser varjabbiltà għolja, firxa żgħira tfisser varjabbiltà baxxa f'distribuzzjoni.

How do you find the interquartile range example?
Q3 is the middle value in the second half of the data set. Again, since the second half of the data set has an even number of observations, the middle value is the average of the two middle values; that is, Q3 = (6 + 7)/2 or Q3 = 6.5. The interquartile range is Q3 minus Q1, so IQR = 6.5 – 3.5 = 3.
Is Q3 an interquartile range? The interquartile range is equal to Q3 minus Q1. For example, consider the following numbers: 1, 3, 4, 5, 5, 6, 7, 11.
