The interquartile range (IQR) is the difference between the upper (Q3) and lower (Q1) quartiles, and describes the middle 50% of values when ordered from lowest to highest. The IQR is often seen as a better measure of spread than the range as it is not affected by outliers.

So, the range is the biggest distance between any two data points. It's a way of measuring variability. The midrange, on the other hand, is the point half way between the two most extreme values. ... So, by being the middle point between the max and min, the midrange is actually trying to measure the center of the data.

Dispersion. ... Interquartile Range (IQR) It is the better measure of dispersion than the Range. It uses the terms Q1, Q2, Q3, Q4 to denote each quarter of the data set. Q1 lies at the 25th percentile, Q2 lies at the 50th percentile or median, Q3 lies at the 75th percentile, and Q4 lies at the 100th percentile.

The middle half of the data falls between the first and third quartiles, and is centered about the median. The difference between the first and third quartiles, called the interquartile range, shows how the data is arranged about the median. ... A larger interquartile range shows that the data is more spread out.

It is also called the 75th percentile. The interquartile range (IQR) is the difference between the upper (Q3) and lower (Q1) quartiles, and describes the middle 50% of values when ordered from lowest to highest.

The range is the set of all second elements of ordered pairs (y-coordinates). Only the elements "used" by the relation or function constitute the range. Domain: all x-values that are to be used (independent values). Range: all y-values that are used (dependent values).

The difference between the first and third quartiles, called the interquartile range, shows how the data is arranged about the median. A small interquartile range indicates data that is clumped about the median. A larger interquartile range shows that the data is more spread out.

y = range( X ) returns the difference between the maximum and minimum values of sample data in X . If X is a vector, then range(X) is the range of the values in X . If X is a matrix, then range(X) is a row vector containing the range of each column in X .

The difference between the lowest and highest values. In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9, so the range is 9 − 3 = 6. Range can also mean all the output values of a function. The Range (Statistics)
