Best Answer

first you take a group of numbers and order them from smallest to largest

next you find the median or the quartile2 then you find quartile1 and 3 then you subtract quartile 1 and 3 then you have your answer :)

for help with math, I suggest you find a tutor. Talk to your parents, (if you are 16 and younger) to see if they can find a tutor for you. you can also go to www.math.com for more help, hope I've helped!

1. look at the numbers 2. find a math pattern to follow 3. try your pattern with all the numbers 4. if it doesn't work try a different math pattern

IQR = Inter Quartile RangeIQR = Inter Quartile RangeIQR = Inter Quartile RangeIQR = Inter Quartile Range

Iqr stands for inter quartile range and it is used to find the middle of the quartiles in a set of data. To find this, you find the lower quartile range and the upper quartile range, and divide them both together.

The IQR is 7.5

Step 1: Find the upper quartile, Q3.Step 2: Find the lower quartile: Q1.Step 3: Calculate IQR = Q3 - Q1.Step 1: Find the upper quartile, Q3.Step 2: Find the lower quartile: Q1.Step 3: Calculate IQR = Q3 - Q1.Step 1: Find the upper quartile, Q3.Step 2: Find the lower quartile: Q1.Step 3: Calculate IQR = Q3 - Q1.Step 1: Find the upper quartile, Q3.Step 2: Find the lower quartile: Q1.Step 3: Calculate IQR = Q3 - Q1.

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.

IQR = Inter-Quartile Range = Upper Quartile - Lower Quartile.

to calculate Q1 and Q3, you must first find Q2 - the median. count from wither end of the sample until you find the sole middle number, or find the average of the 2 middle numbers. then, complete the same process to the left of Q2 for Q1, and also on the right for Q3. the IQR is just Q3 - Q1.

The IQR is 48. But for only 6 observations, it is an absurd measure to use.

No. The IQR is found by finding the lower quartile, then the upper quartile. You then minus the lower quartile value from the upper quartile value (hence "interquartile"). This gives you the IQR.

No.

The IQR gives the range of the middle half of the data and, in that respect, it is a measure of the variability of the data.

Because the IQR excludes values which are lower than the lower quartile as well as the values in the upper quartile.
