Five-number summary A technique that uses five numbers to summarize the data:. Joe Flom is the last living named partner of one of the most prestigious law firms in New York, “Skadden, Arps.” Flom grew up in a Jewish family during the depression, did well in school, and eventually got into Harvard law without a college degree, and graduated as one of the very top in his class. IQR = 10.5 – 3.5 = 7, so 1.5·IQR = 10.5.

A percentile is not a percent;. For example, a set of observations can be summarised and the largest among them can be communicated. To determine if there are outliers we must consider the numbers that are 1.5·IQR or 15 beyond the quartiles.

To determine if there are outliers we must consider the numbers that are 1.5·IQR or 10.5 beyond the quartiles. Using the logic of tagging points that are 1.5 x the distance of the interquartile range away from the upper and lower bound of the interquartile range, we designate anything above 30 (15 + 10 x 1.5 = 30) and below -10 (5 - 10 x 1.5 = -10) as outliers. 81 + 13.5 = 94.5.

So we have outliers, outliers. First quartile – 1.5·IQR = 3.5 – 10.5 = –7. 13 minus seven is six, and then you subtract another .5, is 5.5.

The minimum value, Q 1 (being the bottom of the box), Q 2 (being the median of the entire set), Q 3 (being the top of the box), and the maximum value (which is also Q 4).So I need to order the set, find the median and the sub-medians (or hinges), note the largest and smallest values, and then list the required. This approach uses the interquartile range (Q3 - Q1 values) to assess how far outliers may exist. 18 plus 7.5 is 25.5, or outliers, outliers greater than 25, 25.5.

For instance, the above problem includes the points 10.2, 15.9, and 16.4 as outliers. Outliers (1.5 x IQR Rule) - Now that we have a measure of spread, we can use it to identify values that are much farther from the center than usual. 72, 25, 70, 73, 77.
