A box-and-whiskers plot is a good way to show the spread (or variation) of a set of data visually.

A box-and-whiskers plot shows both the median and extremes of a data set. Median: the middle term, or the average of the two middle terms, when the terms are arranged from least to greatest. Lower Extreme Upper Extreme Extremes: the minimum and maximum values

The extreme values are used to find the range of the set of data by finding the difference between the lower extreme and the upper extreme. Upper Extreme – Lower Extreme = RANGE Lower Extreme Upper Extreme EXTREMES

Quartiles: the medians of the lower and upper halves of the data. Upper Quartile – Lower Quartile= INTERQUARTILE RANGE

Box-and-whiskers plots are uniform in the use of the box Box-and-whiskers plots are uniform in the use of the box. Therefore, no matter the size of each section, the data is evenly divided in quarters (25%). 25%

Therefore the entire box-and-whiskers plot is equal to 100% of the data.

No matter how the diagram appears to be equally or unequally divided, each section is always 25%

Mr. Patterson surveyed members of the school band and members of the school orchestra to find out how many CDs each owned. His data is shown in the box-and-whiskers plot on the left. a) Which group has a higher percent of members with 20-30 CDs? The band Which group has the higher range? Equal! c) Which group has the higher interquartile range? The orchestra

The double box-and-whiskers plot below shows the test scores for two classes. a) Which class had the lowest test grade and what was the score? 55 in Mr. Johnson’s class b) Which class had the higher median and what was it? 85 in Ms. Winston’s class If 80 is a passing grade, which class had the higher percent of students who passed? Explain your answer. Ms. Winston’s class. Mr. Johnson had 50% passers and Ms. Winston had over 50% passers.
