Explanation / Answer

What does this measure of central tendency tell you about the most typical binge drinker?

Race Percent Binge Drinkers in 1999 White 49.2 Black 15.5 Asian/Pacific Islander 23.1 Other 39.6 31.85 Mean Ex/n 31.35 Median (n+1)/2 #N/A Mode Most frequently repeated measure What is the measure of central tendency most appropriate for these data? Why? Ideally, in cases where, there are outliers, Median is the most effective measure of central tendency because it is less suspectible to outliers. However, looking at the answers above, mean seems to be the most appropriate as this data has datapoints at specific intervals so it does not have any outliers

What does this measure of central tendency tell you about the most typical binge drinker?

The most typical binge drinker race would have around 32 % of its population as binge drinker
