The mean for the data that I collected is: (0 x 4 = 0) + (1 x 1 = 1) + (2 x 1 = 2) + (3 x 0 = 0) + (4 x 0 = 0) + (5 x 1 = 5) + (6 x 2 = 12) + (7 x 1 = 7) + (8 x 1 = 8) + (9 x 0 = 0) + (10 x 1 = 10) + (11 x 13 = 143) = 188 188 / 25 = 7.52

10
The Mode for the data I collected is 11 years, since it is the most common number of years by far in my sample.

11
The Median for the data that I collected is 11 years. This is because over half of the people that I surveyed (13 out of 25 people) said that they have lived in Poolesville for 11 years.

12
The range for the data that I collected was 11 years. This is because the number of years that people have lived in Poolesville ranged from zero (0) years to eleven (11) years.

13
The mode is the best representation for the Central Tendency of the data that I collected. This is because over half of the people that I surveyed (13 out of 25) said that they have lived in Poolesville for 11 years.

14
My sampling technique was a convenience sample. I surveyed 6 th grade students at John Poole Middle School. My sampling was biased because I only surveyed sixth-graders, so their answers were limited to eleven or less. It was also biased because the survey was taken at a school in Poolesville, as opposed to a random location.
