What is the 1.5 IQR rule?

Using the Interquartile Rule to Find Outliers

Multiply the interquartile range (IQR) by 1.5 (a constant used to discern outliers). Add 1.5 x (IQR) to the third quartile. Any number greater than this is a suspected outlier. Subtract 1.5 x (IQR) from the first quartile. Any number less than this is a suspected outlier.

What is the median of these numbers?

Mean vs Median

The mean (average) is found by adding all of the numbers together and dividing by the number of items in the set: 10 + 10 + 20 + 40 + 70 / 5 = 30. The median is found by ordering the set from lowest to highest and finding the exact middle. The median is just the middle number: 20.

How do you find q1 and q2?

In this case all the quartiles are between numbers:

  • Quartile 1 (Q1) = (4+4)/2 = 4.
  • Quartile 2 (Q2) = (10+11)/2 = 10.5.
  • Quartile 3 (Q3) = (14+16)/2 = 15.

How do you interpret Iqr?

What is the best interpretation of the IQR? The IQR represents the typical temperature that week. The IQR represents how far apart the lowest and the highest measurements were that week. The IQR approximates the amount of spread in the middle half of the data that week.
