Project Part I
_____ Collection of Data (8 points)
 | At least 5 variables of which at least 4 are quantitative. |
| At least 100 observations per variable. |
_____ Computation of Descriptive Statistics (8 points)
| For each quantitative variable, compute the mean, median, standard deviation, first and third quartiles, range, interquartile range, and interquartile range. Find any outliers. |
| For each qualitative variable, compute the sample percentage for each answer. Identify any outliers. |
| As appropriate, compute statistics for paired data. For example, if you asked people their gender and age, compute the average age for just the males and the average age for just the females. |
_____ Graphs and Charts (8 points)
| At least 6 charts which reveal something useful about the data. For example, you might consider a box plot or stem and leaf plot for the quantitative variables, or perhaps a pie chart or bar graph for the qualitative variables. |
| You should create charts for interesting paired data, for example, a bar chart showing the heights of freshmen, sophomores, juniors, and seniors. |
_____ Analysis of the Results (16 points)
| How exactly did you collect your data? Describe any relevant factors such as location, time of day, etc. |
| Were there any biases or weaknesses in your sampling process? (It is ok if there were, so long as you identify them and their causes.) How many people refused to answer? In other words, how well do you think your sample represented your population? |
| Examine each of the statistics you found above (means, medians, std deviations, etc) and comment on what they tell you. (For example, "since our s is large, then we know... " etc) Not every statistic will be meaningful for every variable or every group. |
| Examine the graphs you created. What conclusions can you draw from them? |
| Discuss any outliers you had and their possible causes. |
_____ Report format (5 points)
| Report looks professional and is well-written. Spelling and grammar are correct. It is written as a report, not a list of answers to questions. |
| The report is well-organized and readable. |
| Color and graphics used well. |
