MATH 107 Week 8 Participation Latest-UMUC

This is the last graded discussion. The due date is March 3 (with NO extra days with penalty) but, if

possible, post your response by Wednesday of this week so that your classmates will be able to benefit

from your post.

When reviewing for an exam, it is a good idea to take some time to consider what types of questions will

be on the exam. (What should I study?) The answer to this question will guide you as you study for the

exam.

this discussion is your opportunity to share with

This discussion is your opportunity to share with your classmates what you have determined will be a

sample final exam question.

Post a question that you think will be reflective of one of the final exam questions and then give a detailed

solution to the question. Follow the discussion rubric as you write out the solution. This should not be a

problem from the text – make up one of your own.

Take some to review the sample questions/solutions of your classmates. If you see a post that is helpful

to you – let your classmate know.

Hopefully, this discussion will contain lots of different types of problems that will give you an additional

review for the final exam.

After the exam, you might want to check back and see if your type of problem was included on the final

exam. If yes, then it would be reasonable to conclude that you are indeed quite brilliant…heh, heh, heh

Here is where you will post your extra credit problem. This problem is optional. You can earn up to 10

extra credit points for your participation problems by posting a problem from one of the previous

discussion problem sets that has not already been posted.

Label the problem as extra credit.

Just to clarify, the Week 8 discussion post will be a problem that you make up and the Extra Credit

problem will be from the previous 7 weeks discussion problems.

MATH 107 Week 5 Linear project Latest-UMUC

Curve-fitting Project – Linear Model

(Due at the end of Week 5)

Instructions

For this assignment, collect data exhibiting a relatively linear trend, find the line of best fit, plot the data

and the line, interpret the slope, and use the linear equation to make a prediction. Also, find r2 (coefficient

of determination) and r (correlation coefficient). Discuss your findings. Your topic may be that is related to

sports, your work, a hobby, or something you find interesting. If you choose, you may use the suggestions

described below.

A Linear Model Example and Technology Tips are provided in separate documents.

Tasks for Linear Regression Model (LR)

lr 1 describe your topic provide your data

(LR-1) Describe your topic, provide your data, and cite your source. Collect at least 8 data points. Label

appropriately. (Highly recommended: Post this information in the Linear Model Project discussion as well

as in your completed project. Include a brief informative description in the title of your posting. Each

student must use different data.)

The idea with the discussion posting is two-fold: (1) To share your interesting project idea with your

classmates, and (2) To give me a chance to give you a brief thumbs-up or thumbs-down about your

proposed topic and data. Sometimes students get off on the wrong foot or misunderstand the intent of the

project, and your posting provides an opportunity for some feedback. Remark: Students may choose

similar topics, but must have different data sets. For example, several students may be interested in a

particular Olympic sport, and that is fine, but they must collect different data, perhaps from different

events or different gender.

(LR-2) Plot the points (x, y) to obtain a scatterplot. Use an appropriate scale on the horizontal and vertical

axes and be sure to label carefully. Visually judge whether the data points exhibit a relatively linear trend.

(If so, proceed. If not, try a different topic or data set.)

(LR-3) Find the line of best fit (regression line) and graph it on the scatterplot. State the equation of the

line.

(LR-4) State the slope of the line of best fit. Carefully interpret the meaning of the slope in a sentence or

two.

(LR-5) Find and state the value of r2, the coefficient of determination, and r, the correlation coefficient.

Discuss your findings in a few sentences. Is r positive or negative? Why? Is a line a good curve to fit to

this data? Why or why not? Is the linear relationship very strong, moderately strong, weak, or

nonexistent?

(LR-6) Choose a value of interest and use the line of best fit to make an estimate or prediction. Show

calculation work.

(LR-7) Write a brief narrative of a paragraph or two. Summarize your findings and be sure to mention any

aspect of the linear model project (topic, data, scatterplot, line, r, or estimate, etc.) that you found

particularly important or interesting.

You may submit all of your project in one document or a combination of documents, which may consist of

word processing documents or spreadsheets or scanned handwritten work, provided it is clearly labeled

where each task can be found. Be sure to include your name. Projects are graded on the basis of

completeness correctness ease in locating

completeness, correctness, ease in locating all of the checklist items, and strength of the narrative

portions.
