MAT 126 MAT/126 MAT126 Week 5 Discussion 1/DQ 1 Week Five Discussion {{LATEST}} This Discussion will give you
the opportunity to calculate or identify the three measures of central tendency. You will be asked to select an appropriate
real life situation in which one measure would be more appropriate than the other two measures of center.
1. Select a topic of interest to you and record the topic in your posting, for example: What is the average number of
hours people watch TV every week? Make sure the question you ask will be answered with a number, rather than
answers with words. 2. Write a hypothesis of what you expect your research to reveal. Example: Adults 21 years and
over watch an average of 2.5 hours of TV per day. 3. Sample at least fifteen people and record their data in a simple
table or chart; study the examples from Section 12-3. 4. You can gather your data at work, on the phone, or via some
other method. This is your Sampling Design. Which of the four sampling techniques best describes your design? 5.
Explain in moderate detail the method you used to gather your data. In statistics this venture is called the Methodology.
6. Make sure you break your sample into classes or groups, such as males/females, or ages, or time of day, etc. 7.
Calculate the mean, median, and mode for your data as a whole. 8. Now calculate the mean, median, and mode of
each of your classes or groups. 9. Indicate which measure of central tendency best describes your data and why.
Then compare your results for each class or group, and point out any interesting results or unusual outcomes between
the classes or groups. This is called a comparative analysis using our results to explain interesting outcomes or
differences (i.e., between men and women). 10.Comment on at least two of your classmates postings. Make sure you
comment on their hypothesis (topic), their design, and whether you agree or do not agree with their best measure of
central tendency. Your initial post should be at least 150 words in length. Respond to at least two of your classmates
posts by Day 7.
