FIGURE OUT THE 5 NUMBER SUMMARY Use these numbers to create the 5 number summary. It may be easier to put them in order or do a dot plot!

IDENTIFYING MEDIAN Work your way to the middle! If you have an even number of entries, there won’t be a middle number in your set!

IDENTIFYING Q 1 & Q 3 Find the median of the lower half of the data for Q 1 Find the median of the upper half of the data for Q 3

WRITE OUT THE 5 NUMBER SUMMARY The minimum value was 0 Quartile 1 was 0 The median was 1 Quartile 3 was 2 The maximum value was 7

DRAWING THE BOX PLOT Draw a numberline including the minimum and maximum values. The minimum value was 0 Quartile 1 was 0 The median was 1 Quartile 3 was 2 The maximum value was 7

LABEL THE 5 PARTS ON NUMBERLINE The minimum value was 0 Quartile 1 was 0 The median was 1 Quartile 3 was 2 The maximum value was 7

IQR is the Interquartile Range. Subtract Q 1 from Q 3 to get IQR. In the last example: Q 1 was 0 and Q 3 was 2, so the IQR= 2

DRAW THE BOX AND WHISKERS! The box goes between Q 1 & Q 3
