Question 1 The range is the simplest measure of variation; to obtain it, we subtract (the lowest value +1) from (the highest value). The pros of the range are that it gives us the full scope of extremes of a sample size. The cons of the range are that when the outliers are too dramatic and far away from the other numbers, they give us an inaccurate depiction of sample size. For example, due to the income inequality, the minimum wage should be at close to \$25.00 per hour (Dalton, week 6). The interquartile range pros are that it more accurately represents the majority of data. Its cons are it ignores the most extreme data points.

On Tuesday night, December 8th of 2015. I waited impatiently by the Great Hall of the CCNY Shepard Hall. Seven twenty-three pm I looked at the clock on my phone.

His melding of the song’s lyrics with jocular remarks perfectly embodies the mixing and matching that occurs in jazz performances. Armstrong’s comments on his makeup and how hard the pianist is playing relax the atmosphere and sustain my attention on what he is saying. The instrumental play reacts to what he is saying, with his voice acting as a conductor, pulling the drums, bass, piano, trombone, and finally clarinet into playing. It seems that a lot of call and response is going on in this…

Nine, the age I was when my fascination with golf began. I still do not know why I so desperately wanted to golf, but I do know that I was determined to learn. That summer between fourth and fifth grade, I was registered for a day camp by my mother, who was confused by my new interest, though supportive nonetheless. Every day, for three weeks, I would arrive at the golf course early in the morning, eager to play and equipped with my lustrous deep red set of metallic clubs. We were divided into…
