Overview
The topic of our study was 'what Cleveland Sports team do most people prefer to watch?' We used a sample from our high school and we used the four main Cleveland sports
teams: the Indians, Browns, Cavs, and the Monsters.
We also wanted to look and see if there existed a difference among
gender regarding which Cleveland sports team was preferred to be
watched. We searched the internet to try and find previous studies or
information relating to our topic. Information we found showed that
football was actually America's favorite past time sport to watch.
But information we gathered also showed that the success of a team
increases the amount of people that view their games. This information
was relevant because the Cavaliers were the only successful team in
Cleveland, leading us to believe that the Cavaliers would be the highest
chosen Cleveland sports team to watch.
We obtained our sample by randomly selecting 80 males and 80 females, using a random generator in Minitab, and sent out a survey to these people. Overall, we received back 115 of the 160 surveys that we sent out to the selected sample. From the data we received, we could make numerous observations. It was clear that an overwhelming majority chose Cleveland Cavaliers basketball as their favorite sport to watch on TV. The Indians were chosen second most, far behind the Cavaliers though. The Cleveland Browns came in third slightly behind the Indians, while the monsters were the least chosen team. These results were the same for both males and females in our sample. First, we put our data through a chi-squared test to determine if there was a difference among sports preferences between the gender. The test showed that there was inconclusive evidence so support the idea that there exists a difference between sports viewing preference and gender in the sample we took. However, our test was invalid due to the fact that not all assumptions were met. Two of our expected cell counts did not exceed five.
After that test, we decided to run a second one determining if there exists a preference between the sports, where there is an unequal distribution among the sports concerning which one people enjoy to watch the most. We used a chi-squared goodness of fit test and rejected our null hypothesis. The conclusion we drew showed that there is enough evidence to suggest that not all sports are enjoyed to be viewed equally. From our graphs, this conclusion can clearly be scene. The Cavaliers are chosen by about two-thirds of the students taken in the sample and the Lake Erie Monsters are in last place only receiving 5% of the responses.
We did recognize that there were a few weaknesses which effected our survey. Some were response bias, non response bias, and inadequate information on our survey. Also, we decided that we should only extrapolate to suburban Cleveland schools.
One day there was a fire
in a wastebasket in the Dean's office and in rushed
a physicist, a chemist, and
a statistician. The physicist immediately starts to work
on how much energy
would have to be removed from the fire to stop the combustion. The
chemist works on which reagent would have to be added to the fire to
prevent
oxidation. While they are doing this, the statistician is setting fires
to all the other wastebaskets in the office. "What are you doing?" they
demanded.
"Well to solve the problem, obviously you need a large sample size" the
statistician replies.

A man who travels a lot was concerned about
the possibility of a bomb on board his plane. He determined the
probability of this, found it to be low but not low enough for him. So
now he always travels with a bomb in his suitcase. He reasons that the
probability of two bombs being on board would be infinitesimal.
