Number of Wins by the Atlanta Braves (19972012)
94, 89, 91, 86, 72, 84, 79, 90, 96, 101, 101, 88, 95, 103, 106, 101
4. Use the above data (“Number of Wins by the Atlanta Braves”) to create a histogram. You must first make a frequency table (3 columns with tallies) using intervals (groups of numbers).
5. Use the above data (“Number of Wins by the Atlanta Braves”) to create a stemandleaf plot.
6. Use the above data (“Number of Wins by the Atlanta Braves”) to find the following stastistics then create a box and whisker plot.
Median = _____ Lower Quartile = ______ Upper Quartile = ______ Lower Extreme = ________
Upper Extreme = _____ Range = ______ IQR = ______
7. If the Braves had a really bad season in 2013 and only win 52 games, which measure of center would be the most affected and why? (Circle One) Mean Median Mode

8) Use the above data (Number of Tim Hudson Wins) to create a line plot.
9) What is the center of your graph? _______ Any outliers? _________
Any clusters? _______________ Any gaps? _______________
10) If Tim Hudson had a season previously in his career where he was hurt and only won 2 games, which measure of center would be most affected? (Circle One) Mean Median Mode
Homeruns Hit by Brian McCann in his 1^{st} 5 Season
5, 24, 20, 23, 21, 21
11) Use the above data (“Homeruns Hit by Brian McCann”) to find the following measures of center
Mean = _______ Median = ________ Mode = _________
12) Use the above data (“Homeruns Hit by Brian McCann”) to find the mean absolute deviation (MAD).
MAD = ________
13) Looking at the data on Brian McCann homeruns, which measure of center, mean or median, would best show the typical season of homeruns for him and why? ______________________________________________________________________________________________________________________________________________________________________________________________
14) The following set of numbers shows the price of different tickets at Turner Field. Given the mean of the snacks, find the missing snack value: {$13, $16, $14, $20, $19, x} Mean = $16 x = $_____
