Assignment Instructions/ Description
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 is made of the following tasks. Each task must be addressed in the statistics project report in order to qualify for full credit:
• Task 1: identify: o Yourself (student’s name) o name of project o purpose of project
• Task 2: Conduct Data Collection. Provide: o Raw data used (sample size must be at least 10 individual raw scores) o source of the data
• Task 3: Calculate Measures of Central Tendency and Variability: o median, sample mean, range, sample variance, and sample standard deviation (show work)
• Task 4: Frequency Distribution. Provide o Raw data in frequency table format (1st column of value “intervals”, and 2nd column shows “frequency”: number of scores falling within each interval)
• Task 5: Histogram: o Create histogram using frequency table constructed in Task 4 o NOT a vertical bar chart! o x – axis must show intervals, y – axis must show frequencies
• Task 6: Compare Raw Data Distribution to “Standard” Normal Distribution. Using your raw data gathered in Task 2 and the sample mean and sample standard deviation calculated in Task 3, calculate: o percentage of your raw data falling within one standard deviation of the mean; o percentage of your raw data falling within two standard deviations of the mean; o percentage of your raw data falling within three standard deviations of the mean
• Task 7: Communicating Evaluation, Analysis, Results, and Conclusions. Provide two to three paragraphs that: o interpret your statistics and graphs; o answer whether your percentages calculated in Task 6 indicate that your data distribution (shown in the histogram created in Task 5) is the same as the 68/95/99.5% “standard” normal distribution? Be sure to explain why you think your data distribution does or does not match the “standard” normal distribution. o relate to the purpose of the project
