It tells you that middle half the observations lie within the IQR.
You find the semi interquartile range by subtracting the 25th percentile (Q1) from the 75th (Q3) percentile and dividing by 2. So, the formula looks like : (Q3 - Q1)/2

We can't answer that without knowing the set of numbers.
for the data set shown below find the interwar range IQR. 300,280,245,290,268,288,270,292,279,282
The interquartile range of a set of data is the difference between the upper quartile and lower quartile.
The Inter-quartile range is the range of the middle half of the data. It is the difference between the upper and lower quartile.Example: 35,80,100 110,120,120,170,180.The Inter-quartile range would be 145-90 or 55To find the interquartile range, you:1) Arrange the data in numerical order.2) Then find the median of the data sets.3) Find the median of the top half and bottom half. (of the set of numbers)4) The groups you now have are "quartiles"5) Find the interquartile range. (subtract the smaller range from the range)
The standard deviation is the value most used. Others are variance, interquartile range, or range.

Here is one pair: {1, 2, 3, 6, 7} and {1, 2, 5, 6, 7} The fact that the range and interquartile range are the same fixes the relative positions four points in each set - all but the median.

It is a measure of the spread of a set of observations. It is easy to calculate and is not distorted by extreme values (or mistakes). On the other hand it does not use all of the information contained in the data set.
The interquartile range can be more useful when the first and fourth quartiles contain very little data, in other words there are only a very few high or low data points.
