Math 120 project

MAT 120, Probability and Statistics Project DUE: July 30, 2019

This project will be done in two parts. The first part will include collecting data, calculating descriptive statistics and graphing. The second part will include estimation, hypothesis testing, and inferential analysis.

PART 1

After collecting “normally distributed” data for your project (see Project Ideas document and verify ideas with me if necessary), please type and print your document in report form answering the following questions. You will be graded on content, style and creativity. The project weights the same as a test.

1. What data are you collecting? How did you collect it? Why is it significant to collect this type of data? Why you suspect the distribution is bell-shaped and symmetrical?

2. Begin by making graphical displays for data. Construct a dot plot or stem plot to quickly look at the data. What is the overall shape of the data? (Note: If the data appears skewed, you will need to collect another data set that follows a bell-shaped distribution.)

3. Descriptive Statistics: Calculate the following summary statistics for your analysis and fill in the table. Remember that your calculator can generate these statistics in 1:1-Var Stats after listing the raw data.

	n	Mean	Standard Deviation	Min	Q1	Median	Q3	Max

4. Comment on where the data is centered and how it is dispersed.

5. Create a histogram after making a frequency distribution and mark the mean.

6. Are there any outliers? Use the formulas learned in class and the above statistics to determine if there are any. Would it be reasonable to omit any of the outliers as “bad data?”

7. Create a boxplot and explain if it shows that the data is symmetrical and why.

8. Make any additional comments describing the data set.
