- Compute mean, median, and mode
- State when the mean and median are the same
- Compute a trimmed mean
- Understand how the difference between the mean and median is affected by skew
- State how the measures differ in symmetric distributions
- State which measure(s) should be used to describe the center of a skewed distribution
- Determine the relative variability of two distributions
- Compute the range, inter-quartile range, and variance
- Estimate the variance from a sample

There are a number of assignments this week, as usual.

This week’s activity covers descriptives and charts.

Don’t forget about your chapter quizzes! Find them in the Quizzes menu in D2L.

Choose a question from the end of chapter 2 in the section called “Exercises” to answer. Post the question and your answer, and make sure to justify your response.

For example, if you determine that a type of statistic is descriptive, provide your reasoning being specific about the problem presented and your answer.

Next, respond to another students’ answers by asking a question for clarification, providing a personal experience, posting a thought-provoking question, taking a controversial, but professional stand, adding something new to the conversation, quoting another student’s comment and add an additional idea based on this comment, etc.

Your responses should be respectful and offered in a professional manner. You may wish to review the behavior Course Policies to help frame your response. Remember, you will be responding about the specific idea, issue, or question.

*You may not answer a question that has been previously addressed.*
