Given are the ages of motorcyclists at the time they were fatally injured in traffic accidents. What kind of diagram/graph is most effective to dramatize the dangers of motorcycles; Pareto chart, pie chart, etc.? Create it. DO NOT MAKE A HISTOGRAM UNLESS IT IS A PICTOGRAPH. Your graph must fill the entire page.

What are the mean, median and mode? Show all work and calculations.
Is it unusual to find a 45-year-old in this group? Prove it using range rule of thumb.
Between what ages would you find 68% of the fatalities? Prove it using range rule of thumb.
Are there any outliers? What are they? Prove it showing the calculation of
z-scores.
DATA: 17 38 27 14 18 34 16 42 28 24 40 20 23 31 37 21 30 25 17 28 33 25 23 19 51

Definition Definition Measure of central tendency that is the value that occurs most frequently in a data set. A data set may have more than one mode if multiple categories repeat an equal number of times. For example, in a data set with five item—3, 5, 5, 29, 473—the mode is 5 because it occurs twice and no other value occurs more than once. On a histogram or bar chart, the element with the highest bar represents the mode. Therefore, the mode is sometimes considered the most popular option. The mode is useful for nominal or categorical data (e.g., the most common color car that users purchase), but it is problematic for continuous data because it is more likely not to have any value that is more frequent than the other.
