Discussion Board Problem Assignment | Online Homework Help

Please answer the attached discussion board question. Let me know if you have any questions.

Unit 5 Discussion

For this assignment, you will participate in a discussion about how to properly analyze the association between two variables, depending upon if those variables are quantitative or qualitative. You have seen many techniques to determine if there is an association present between two variables for which you have data. In this assignment, it will be up to you to determine the appropriate analysis for the situation.

Examples

• Example 1:Safety experts are trying to determine how long it takes a specific brand of car to come to a complete stop. They have determined that the speed of the car has a large impact on how long it takes to come to a complete stop. They decide to gather data by having the car go 10, 30, 50, 70, and 90 miles per hour and then determine how many feet it takes to come to a complete stop at each of these speeds.
• Example 2:Drama students at a large university recently put on a production of Phantom of the Opera. Some students jokingly said that only the female students went to see the play, and one of the students wanted to see if a higher proportion of female students had seen the play than males. To gather data, the student went around campus randomly selecting students and asking them their gender and if they went to see the production.

Instructions

1. Complete the following on the Discussion Board for both Example 1 and Example 2:

• • State the explanatory and response variables in each example, and state what type for each of the variables.
  • For each example, discuss an appropriate analysis or procedure to use to determine if there is an association between the two variables.

2. Be sure to read and respond to at least two other posts. When you respond to the posts, add clarification, ask questions, or add constructively to the discussion.

Participation Requirements:

Original discussion forum posts:

• Create a thread for your original post identified with your name.
• Prepare a quality, substantive post that addresses the objectives of the discussion forum and the expectations set forth in the grading rubric
• Include supportive evidence; such as direct applicable experience and expert sources.
• Due no later than Wednesday, 11:59 pm, CT

Responses to discussion forum posts:

• Prepare and post substantive responses to at least two peers by Friday, 11:59 pm, CT
• Continue to remain engaged in substantive discussion with peers and the instructor throughout the week

• Please answer Separate Question/Statement Below.
• While the speed of a car is the primary factor in determining the distance it takes to stop, there are other variables that can change the stopping distance. Some of these are the condition of the surface that the car is using to stop, the temperature of the surface, and the weight of the car. For example, if it is raining, then the stopping distances, probably will be longer than on dry pavement. A 2,500 pound sports car can stop in a shorter distance than a 5,000 pound sedan, given that both cars have the same braking system design. My point, here, is that, even a relatively simple experiment can be more complicated than it appears.
