Finding the Inter-quartile Range (IQR)Step 1: Write the speeds in order from least to greatest.

162, 162, 162, 163, 166, 167, 167, 170, 176, 185

Step 2: Find the median of the data since the median separates the data into two halves.

162, 162, 162, 163, 166, 167, 167, 170, 176, 185• Since there are two numbers in the middle we have to find

the mean of the two.

(166 + 167) / 2 = 166.5

Steps Continued…

Step 3: Find the median of the upper half of the numbers________. This number is called the upper quartile.

• Circle this number in your step 1 and label it UQ

Step 4: Find the median of the lower half of the numbers_______. This number is called the lower quartile.

• Circle this number in your step 1 and label it LQ

Steps Continued…

Step 5: The middle half of the data goes from the upper quartile (UQ) to the lower quartile (LQ).

Subtract the LQ from the UQ. 170 – 162 = 8

This is called the inter-quartile range of the scores!!The IQR describes the variability of the middle 50% of

the data values.

162, 162, 162, 163, 166, 167, 167, 170, 176, 185LQ UQ

Write in your notes:What 5 points do you need to know to find the IQR?

1. Least value 2. LQ3. Median4. UQ5. Greatest value

Find the Stats…Step 1: Order the data…81, 81, 82, 82, 85, 85, 93, 95, 100, 100, 112, 120, 128

• Range:128 – 81 = 47

• Median: 93• Upper Quarter (UQ): (100 + 112)/2 = 106• Lower Quartile (LQ): 82• Interquartile Range: 106 – 82 = 24• Mean: about 96• Mode: No mode because 81, 82, 85, 100 each appear

twice• Outliers: 128

1. Least value 2. LQ3. Median4. UQ5. Greatest value

With these 5 points we can create a BOX and WHISKERS PLOT
