# practice calculating and interpreting the Pearson correlation coefficient and a chi-square test of independence.

### Question Description

IMPORTANT NOTE REGARDING WORD LIMIT REQUIREMENTS:

Please note that each and every assignment has its own word limit.

The purpose of this assignment is to practice calculating and interpreting the Pearson correlation coefficient and a chi-square test of independence.

For this assignment, complete Problems 13.132 and 15.88 in the textbook which are also listed belowInclude your process for conducting the calculations. You can complete the calculations by hand or using Excel or SPSS. If you use Excel or SPSScopy and paste your output results into a Word document.

When addressing each textbook problemprovide a response for each of the six steps of hypothesis testing listed below.

• Pick a test.
• Check the assumptions.
• List the hypotheses.
• Set the decision rule.
• Calculate the test statistic.
• Interpret the results. (What was done? What was found? What does it mean? What suggestions exist for future research?)

Submit a Word document with your problem answers to each of the six steps. If Excel or SPSS was used to complete the assignment, submit the second Word document containing the screenshots to the instructor.

QUESTION 13.132

A sociologist wanted to see if there was a relationship between a family’s educational status and the eliteness of the college that their oldest child attended. She measured educational status by counting how many years of education beyond high school the parents had received. In addition, she measured the eliteness of the school by its yearly tuition, in thousands (e.g., 5 = \$5,000). She

obtained a random sample of 10 families.

QUESTION 15.88

A political scientist developed a theory that after an election, supporters of the losing candidate

removed the bumper stickers from their cars faster than did supporters of the winning candidate. The day before a presidential election, he randomly selected parking lots, and at each selected parking lot, he randomly selected one car with a bumper sticker and recorded which candidate it supported. The day after the election, he followed the same procedure with a new sample of randomly selected parking lots. For both days, he then classified the bumper stickers as supporting the winning or losing candidate. Below are the results. Use hypothesis testing to see if a difference exists between how winners and losers behave.

MUST have at least 5 citations with the page numbers and 5 references in APA format.(The List of References should not be older than 2016 and should not be included in the word count.)

Be sure to support your postings and responses with specific references to the Learning Resources.

It is important that you cover all the topics identified in the assignment. Covering the topic does not mean mentioning the topic BUT presenting an explanation from the context of ethics and the readings for this class

I am a stickler for good organization in everything. I do not want to have to dig for your answers. For instance, if an assignment asks you to provide three examples of something, I suggest that you number them 1-3 so I can find them easily. I also expect that when you submit something as a narrative, you pay attention to how you organize your thoughts: use paragraphs with a topic sentence and supporting sentences; and change paragraphs whenever you introduce a new idea. Also, if there are multiple parts to an assignment, use sub-heads within the paper to organize them.

To get maximum points you need to follow the requirements listed for this assignments 1) look at the word/page limits 2) review and follow APA rules 3) create subheadings to identify the key sections you are presenting and 4) Free from typographical and sentence construction errors.
