Also, how do you find the interquartile range?

Steps:

1. Step 1: Put the numbers in order.
2. Step 2: Find the median.
3. Step 3: Place parentheses around the numbers above and below the median. Not necessary statistically, but it makes Q1 and Q3 easier to spot.
4. Step 4: Find Q1 and Q3.
5. Step 5: Subtract Q1 from Q3 to find the interquartile range.

Subsequently, question is, how do you find the interquartile range of a normal distribution? When working with box plots, the IQR is computed by subtracting the first quartile from the third quartile. In a standard normal distribution (with mean 0 and standard deviation 1), the first and third quartiles are located at -0.67448 and +0.67448 respectively. Thus the interquartile range (IQR) is 1.34896.

Beside above, what does the interquartile range tell you?

The IQR tells how spread out the "middle" values are; it can also be used to tell when some of the other values are "too far" from the central value. These "too far away" points are called "outliers", because they "lie outside" the range in which we expect them.

How do you find the interquartile range of an odd number?

Then, divide your data set in half and find the median of both the lower and upper half. If you have an odd amount of numbers, don't include the middle number. Finally, subtract the median of the lower half from the median of the upper half to find the IQR.
