MATH 225N Week 3 Discussion Measures of Central Tendency and Variation
Paper Instructions
Initial Post Instructions
For this Discussion, you will examine central tendency and variability in terms of pulse rate.
Find and record the pulse rate of 10 different people where you work. Tell us a little about the population from which you drew your data. Describe your findings in terms of central tendency and variability.
Consider using some of the following to help you form your initial discussion post:
- What are your measures of central tendency (i.e., mean, median, and mode)? Which might be the better measure for central tendency and why?
- What is the standard deviation of your data? How variable are the data (range)?
- Are there any outliers? Investigate possible reasons for these outliers, and things that might limit them if further study were to be carried out.
- What are some variables that should be considered in discussing your measures of central tendency and variation? Is there any skewness in your measured data?
- How would you describe this data (i.e. what insights did you gain from this data)?
Follow-Up Post Instructions
Respond to at least two peers or one peer and the instructor. Further the dialogue by providing more information and clarification.

Sample Answer
We explore the so-called Normal Distributions this Week. This includes normal probability distributions, the standard normal distribution, the standard normal distribution Table, the concept of continuous distributions, sampling distributions, and the Central Limit Theorem.
Please don’t forget to use an “outside” resource as part of the content and documentation for your first Post – the Post which is due on or before Wednesday of the Week – the Post where you make the most major contribution to the Weekly discussion posting area and attempt to address the discussion prompts / cues for the Week. It could possibly include a web site that you discovered on the internet at large, so long as the web site is relevant and substantial and does not violate the Chamberlain University policy for prohibited web sites, and so forth. It could possibly include references / resources that you discover through making use of the online Chamberlain University Library ( please click Resources along the left and then click Library to discover the link to the Chamberlain University online Library ) . )
Check out the link below for some information about the so-called Standard Normal Distribution. After that page comes up also click on the normal distribution link from that page to see some more useful and relevant information for our Week 3 concerns and COs.

This is one kind of an example of using an “outside” source / resource to add to what is revealed in our Weekly Lesson in Modules and in our Weekly text book reading.
Please don’t forget to look over the Graded Discussion Posting Rubric each Week to be certain that you are meeting all of the Frequency requirements as well as all of the Quality requirements for graded discussion posting each Week.
