Measures of central tendency are used to describe the middle of a data set.

Find the mean, median and the mode of the data set. 21, 21, 28, 29, 30, 28, 32 mean: 21 + 21 + 28 + 29 + 30 + 28 + 32 = 189 1897 = 27 median: 21 21 28 28 29 30 32 The median is 28. mode: 21, 28 range: 32 – 21 = 11

Don’s music album had the following tracks: 15 rock, 8 classical, 12 hip hop, 10 pop, 15 lullabies, 13 vintage candy jingles and 17 rap. Range: Mean: Median: Mode:

Box and whisker plots A quartile is a percentile measure that divides the total into 4 equal parts.

What is the median? What percentage of data is below the median?

z z Stem and Leaf Plots A Stem and Leaf Plot is a special table where each data value is split into a "stem" (the first digit or digits) and a "leaf" (usually the last digit).
