The table below shows the alcohol consumption per capita for seventeen high-income countries in 2000
according to https://ourworldindata.org.
Country Liters of Alcohol Consumption per Capita in 1980
Australia 9.7
Austria 11.1
Belgium 11.5
Canada 7.6
Denmark 9.8
Finland 5.1
France 13.3
Germany 12.7
Italy 10.8
Japan 6.5
Netherlands 8.6
New Zealand 9.1
Norway 5.2
Sweden 5.9
Switzerland 11.4
United Kingdom 8
United States 7.7
1) Calculate the mean, median, mode, and standard deviation of the liters of alcohol consumption per capita for
these 17 countries. Use your TI-84 calculator or Excel as necessary. If you calculate them by hand, include
your work (neatly written on a separate sheet of paper!!). If you use Excel, include the Excel worksheet. If you
use your TI-84, show what you’ve entered and the results you get. (You could take photos of your calculator
and include those if you’d rather.)
Mean = _______________________
(Round to 1 decimal place.)
Median = ______________________
Mode(s) = ________________________
(if any)
Standard Deviation =_________________________
(Round to 4 decimal places and treat this data set as a whole population, not a sample.)

2) Find the 1st and 3rd quartiles of the data.
Q1=_________________________
Q3=_________________________
3) Neatly draw a Box Plot of the given data in the space below. Label your scale!!
(If you would like to draw it on a computer instead of drawing it by hand, print it out and staple it at the end of
this project.)
4) In what percentile is the 1980 alcohol consumption per capita in the United States? (Round to the nearest

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.
