Question

I need the discussion response post answer for 1 student and 2 student.  The information are attached below.

The best definition for nonparametric statistics I can think of is when data does not fit inside the normal parameters of a normal distribution, it calls for the use of this statistical method. Simply put, nonparametric tests are used when the data cannot be represented by a parametric distribution. If you are trying to conduct a parametric test but your sample size is too small, it would likely instead call for the use of a nonparametric test. Another reason for the use of a nonparametric statistical test is when you have data outliers and you are trying to rack and stack that data. It is also good for finding the exact p-value from the sample, which is unlike parametric tests. However, it is safe to assume that most people are more familiar with parametric tests since they are pulling data from a larger population. The results are likely to be more accurate. The first test that comes to mind is a sign test. The sign test is used to test the null hypothesis that the median of a distribution is equal to the value. This can also be referred to as a distribution free test. The best example I can give of a nonparametric statistical test is with data ranking since that is one of the functions of what nonparametric tests do, especially if the data is skewed or has outliers. Data ranking could be in the form of a histogram to track movie ratings or test scores. Best of luck to you all! Hope everyone passes the course!

1) Nonparametric StaTsTcs is where you don’t have to fnd a distribuTon, more like a ranking, comparing two things. 2) I think it would be an appropriate choice because how would you just need an average number, which you could just rank it rather than give an exact number. Especially iF you aren’t out there to catch each o±spring that the whale has. 3) IF I were to choose a specifc type oF test, I would use the Spearman Rank CorrelaTon. I chose this because I don’t think you could catch every o±spring From a whale iF you’re not there every day. I Feel like having a ranked number rather than having a specifc number would work just as easily. ²hen you could compare 50 years ago to the average you get now. I’m not quite sure on how they catch each o±spring they have unless they’re constantly out there watching them, which might get a tad boring. I personally don’t Feel that global warming has a±ected the whales whatsoever. 4) Something I could use in my daily liFe might be how many upset tax clients we have versus how many are saTsfed. I get tons oF calls each day with someone either griping or someone who is just peachy. We could do a rank and fgure out how we might need to change things in the o³ce.

Description For this assignment, you will participate in a discussion about exactly what nonparametric statistics are and why they are important. You have seen many tests and analyses involving nonparametric statistics. In this assignment, it will be up to you to determine why these tests and analyses are necessary, and in what situations they are appropriate. Example The number of offspring that female blue whales have follows a skewed right distribution. Fifty years ago, researchers tagged ten female blue whales from birth and are counted how many offspring each had over their lifetime. Now researchers want to get similar data to determine if the average number of offspring may be decreasing due to global warming or other environmental changes. Instructions 1. Do the following on the Discussion Board for this example: In your own words, define nonparametric statistics. For this example, discuss why an approach using nonparametric statistics would be appropriate. For this example, what specific test might you use to test whether the average number of offspring has changed over the years? Why would you use this specific type of test? Describe a brief scenario where you may need to use nonparametric statistics in your daily life. 2. Be sure to read and respond to at least two other posts about other possible methods that could be used. When you respond to the posts, add clarification or ask questions discussion.
