Title: Do Now: Find the mean, median, mode, and range of the data.

1
Do Now Find the mean, median, mode, and range of
the data.
• 1.) 14, 17, 18, 19, 20, 24, 24, 30, 32

2
• Find Measures of Central Tendencies and Dispersion

3

5
• Standard Deviation describes the typical
difference (or deviation) between a data value
and the mean.

6
Find the standard deviation of the data. Sketch a
boxplot and histogram.
• 1.) 14, 17, 18, 19, 20, 24, 24, 30, 32
