Example 1:

Regression can be a very powerful tool in business. It can help to find or reinforce relationships between variables. Since I used to be a steel erector, I had to bid projects in order to try to win work. I decided to look at 14 different projects I bid in order to see how strong of a relationship there was between the amount of steel pieces and the bid amount for erecting the steel. In order to take out any large swings in the data, I took out any equipment, profit, and all of the things that don’t pertain to the steel itself. Here is the data and analysis:

As seen in the graph above, the equation for the line of regression is y=394.23x+283.24.

The coefficient of determination, r2, is 0.985. That shows a very strong relationship between the regression line and the data.Persuasive Presentation

This assignment is based on the How to ask about patient satisification? The visual analogue scale is less vulnerable to confounding factors and ceiling effect than a symmetric Likert scale article that you read earlier this week. After you have read the article, you are to answer the following questions in a word document.
What are your general interpretations of Table 4 in terms of the correlations provided in the data table? Using only this information, what would you conclude about the relationship between the two scales in terms of score variance between the two? In either scale – the VAS or the Likert-type questionnaire – the scale is at what level of measurement? There are many that would argue against using a Pearson’s correlation for this relationship. Why is that argument made? (You may need to research a little outside of the course content for this!)In the text “Representing Others’ Ideas through Summary,” on p. 60 the author points out that a writer’s purpose and context will determine the length and content of the text. In this assignment, we will practice writing summaries of various lengths
I’m working on a English question and need guidance to help me study.

Task 1/Reading: Re-Read the text “Representing Others’ Ideas through Summary.”

Task 2/Reading and Annotating: Read and annotate “How Does Religion Affect Happiness Around the World?” by Jill Suttie.

Task 3/Composing to Learn: Take some notes from the article that will help you write a summary.

Task 4/Composing to Communicate: Write three separate summaries. First, write a summary of Jill Suttie’s article in one sentence. Next, write a summary that’s one short paragraph (about 3-5 sentences). Next, write a summary that’s closer to a page (around 250 words). Upload the paper to Canvas.

Make sure that you do the following in each summary: a) include only the main points in your summary, b) write and punctuate the title correctly, c) identify the author, d) identify where and when the text was published and e) write only one work cited page entry
