Topic: Descriptive Statistics
Instructions:
1. For this assignment, you will select a quantitative variable from our Statistics Class Survey data, then display the data and interpret the graphs.
2. Finish this assignment "by hand," in your own handwriting.
Access the data through Google Sheets or Excel. Each row in the sheet contains a student's responses to all of the questions.
3. Each column contains all of the students' responses to the question in the top cell.
4. For this assignment you'll be using one column of your choice that contains the responses to a quantitative variable question.
Answer the questions below:
- Identify which quantitative variable you are investigating. Describe the variable, any units of measurement, and explain how you know whether it is continuous or discrete.
- Compose a frequency distribution of your data set. Be sure to have about five to ten classes. To make this task manageable, sort the values in your column first. In Google Sheets, the sort option is found by clicking on the down arrow in the top cell of the column.
- Use the frequency distribution to graph the frequency histogram of your data on graph paper.
- Showing all work, find the 5-number summary of your data.
- Showing all work, compute the outlier boundaries and identify any outliers.
- Sketch and label a boxplot (show the outliers if you have any) of your data.
- Based on your histogram and the boxplot, describe the shape of the distribution of your variable.
- Summarize your variable by using your graphs to answer the survey question. What was the lowest value? What was the highest value? Are there outliers? If so, are the outliers low or high? What are the lowest or highest values that are not considered outliers? What is the typical value - most common? How does it compare to the median? What do all these mean in the context of the question? (In other words, don't just say the low was 2 and the high was 5, for example, but include the units of measurement.)
