What is the meaing of interquartile range in math?
The interquartile range of a set of data is the difference between the upper quartile and lower quartile.
What is the interquartile range of the following data set 9 30 2 48 42 18 81 5 55 73 11?

What are the two data sets of 5 values which have the same range and interquartile range but the first set is symmetrical and the other set is skewed left?
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.

What does IQR mean in math?
The interquartile range (IQR) is a measure of variability, based on dividing a data set into quartiles. Quartiles divide a rank-ordered data set into four equal parts.

What is a measure of the spread of a set of data?
The standard deviation is the value most used. Others are variance, interquartile range, or range.
What does the Interquartile range tell you about the data set?
It tells you that middle half the observations lie within the IQR.
What is the interquartile range of the following set of numbers?
We can't answer that without knowing the set of numbers.
How do you find the interquartile range of a data?
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)
What are the two data sets of 5 values which have the same range and interquartile range but the first set is symmetrical and the other set is skewed left?

What does interquartile range do?
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.
When might the inter-quartile range be better for describing a data set than the range?
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.
What is the answer a set of data with 7 values that has a mean of 30 a median of 26 a range of 50 and an interquartile range of 36?
