Statistics Project

Assignment Instructions:

You will create a report describing the data. You will use the concepts you have learned in the first three chapters to do that. Your written report should include the statistics or graphs to support your written descriptions of the data. Make sure you thoroughly describe the following characteristics of data: center, variation, distribution, outliers, and time. Include the following items to help your describe the data.

- Create a frequency distribution for all of the scores, construct a histogram based on the data, and describe the distribution.

- Determine the mean score for each year the test was given, and use this data to develop a time-series plot for the data. What are the trends in the data. What are the trends in the data? Be careful to use an appropriate scale so the graph is not misleading.

- Determine the mean, median, and standard deviation of the data and explain what these tell you about the data. Which of these are affected by outliers?

- Find a random sample of the data including a representative sample from each year. Find the mean and standard deviation of this sample and compare these measures to the mean and standard deviation of the population. Explain the process used to find the sample.

- Find the five number summary for the data, construct a box-plot, and use these to further describe the data. Determine if there are any outliers.
