- Which data set has more than
one mode?
A 2, 2, 4, 6, 7, 9 B2, 2, 6, 7, 9
C 2, 2, 4, 6, 9, 9 D2, 3, 4, 6, 9
10. In which data set are the mean,
median, and mode all the same value?
F 1, 3, 3, 3, 5 G 1, 1, 1, 2, 5
H 1, 1, 2, 5, 6 J1, 1, 3, 5, 10
Find the mean, median, mode, and range for each set of
data. Then use each measure to describe the data set.The Most Representative Measure
The measure that is closest to most of the data in the set most accurately
describes the data.
The daily temperatures in °F last week were 98°, 97°, 94°, 75°, 74°, 97°, and
95°. Would mean, median, or mode best describe these data? Explain.
Mean: 90°; median: 95°; mode: 97°; since the median and the mode are close
to most of the data, the median or the mode most accurately describe the data.For each data set, find the mean, median, and mode. Tell which
measure is most useful for describing the data. Explain why.- Ray scored 15, 7, 5, 3, 9, and 15 points
