Statistics Project




Question;For this assignment, you will implement a project involving;statistical procedures. The topic may be something that is related to;your work, a hobby, or something you found interesting. If you choose;you may use the example described below. The project report must;include ? name of project and your name ? purpose of project ? data;(provide the raw data used, and cite the source)?the sample size must;be at least 10 ? median, sample mean, range, sample variance, and sa;mple standard deviation(show work) ? frequency distribution ?;histogram ? percentage of data within one standard deviation of the;mean, percentage of data within two standard deviations of the mean, percentage of data within three standard deviations of the mean (include;explanation and interpretation --- do your percentages imply that;the histogram is approximately bell-shaped?) ? conclusion (several;paragraphs interpreting your st atistics and graphs, relate to the;purpose of the project) If you choose, you may use the following examplefor your data. ? Purpose: Compare the amount of sugar in a standard;serving size of different brands of cereal. (You may instead choose to;compare the amount of fat, protein, salt, or any other category in;cereal or some other food.) ? Procedure: Go to the grocery store (or;your pantry) and pick at least 10 different brands of cereal. (Instead;of choosing a random sample, you might purposely pick from both the;healthy" cereal types and the "sugary" ones.) From the cereal box;record the suggested serving size and the amount of sugar per;serving. The raw data is the serving size and amount of sugar per;serving for each of the 10 boxes of cereal. Before calculating the statistics on the amount of sugar in each cereal, be sure you are comparing;the same serving size. If you use a serving size of 50 grams, you;must calculate how much sugar is in 50 grams of each cereal. For;example, if the box state s that there are 9 grams of sugar in 43 grams;of cereal, there would be 50 times 9 divided by 43, or 10.5 grams in50;grams of cereal. The result of this simple calculation (for each of 10;boxes) is the data you will use in the project statistics and charts.
