Assignment: Non-parametric and parametric tests comparison
Comparison of non-parametric and parametric tests: Statistics shins frequently use the terms parametric and nonparametric tests when conducting analysis. The hypothesis tests of the mean and median were referred to as parametric and nonparametric tests. The mean is a parametric measure, whereas the median is a non-parametric measure. The metric test assumes that your date is distributed in a specific way. Non-parametric tests, also known as distribution free tests, on the other hand, do not. As a result, use this in your assignment comparing non-parametric and parametric tests.
Assignment examples of non-parametric and parametric tests
Give an example of each and discuss when the test is appropriate to use. Then, talk about the assumptions that the investigator should make in order to run the test.
According to the assignment: Non-parametric and parametric tests comparison, a 1-2 sample T Test is an example of a parametric test. When the sample size is greater than 20, this type of analysis is appropriate. A researcher must know and assume that a parametric test can perform well with skewed and non-normal distributions in order to run it. Another assumption that a researcher must make in order to run a parametric test is that the parametric test can perform well when the distribution of each group is different.
A 1 sample sign is an example of a non-parametric test. One reason for using a non-parametric test in a study is that you can use a parametric test with non-normal data. Another reason to use a non-parametric test in a study is when the sample size is very small, the data is original, and the data is ranked. Furthermore, there are outliers that cannot be removed. The data for all groups must have the same dispersion, which is an assumption that must be met by any nonparametric test. As a result, use the concepts to complete the Non-parametric and parametric tests comparison assignment.
ADDITIONAL INSTRUCTIONS FOR THE CLASS
Discussion Questions (DQ)
- Initial responses to the DQ should address all components of the questions asked, including a minimum of one scholarly source, and be at least 250 words.
- Successful responses are substantive (i.e., add something new to the discussion, engage others in the discussion, well-developed idea) and include at least one scholarly source.
- One or two-sentence responses, simple statements of agreement, or “good post,” and responses that are off-topic will not count as substantive. Substantive responses should be at least 150 words.
- I encourage you to incorporate the readings from the week (as applicable) into your responses.
- Your initial responses to the mandatory DQ do not count toward participation and are graded separately.
- In addition to the DQ responses, you must post at least one reply to peers (or me) on three separate days, for a total of three replies.
- Participation posts do not require a scholarly source/citation (unless you cite someone else’s work).
- Part of your weekly participation includes viewing the weekly announcement and attesting to watching it in the comments. These announcements are made to ensure you understand everything that is due during the week.
APA Format and Writing Quality
- Familiarize yourself with APA format and practice using it correctly. It is used for most writing assignments for your degree. Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for APA paper templates, citation examples, tips, etc. Points will be deducted for poor use of APA format or absence of APA format (if required).
- Cite all sources of information! When in doubt, cite the source. Paraphrasing also requires a citation.
- I highly recommend using the APA Publication Manual, 6th edition.
Use of Direct Quotes
- I discourage overutilization of direct quotes in DQs and assignments at the Masters’s level and deduct points accordingly.
- As Masters’s level students, it is important that you be able to critically analyze and interpret information from journal articles and other resources. Simply restating someone else’s words does not demonstrate an understanding of the content or critical analysis of the content.
- It is best to paraphrase content and cite your source.
- For assignments that need to be submitted to LopesWrite, please be sure you have received your report and Similarity Index (SI) percentage BEFORE you do a “final submit” to me.
- Once you have received your report, please review it. This report will show you grammatical, punctuation, and spelling errors that can easily be fixed. Take the extra few minutes to review instead of getting counted off for these mistakes.
- Review your similarities. Did you forget to cite something? Did you not paraphrase well enough? Is your paper made up of someone else’s thoughts more than your own?
- Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for tips on improving your paper and SI score.
- according to Assignment: Non-parametric and parametric tests comparison assignment, The university’s policy on late assignments is 10% penalty PER DAY LATE. This also applies to late DQ replies.
- Please communicate with me if you anticipate having to submit an assignment late. I am happy to be flexible, with advance notice. We may be able to work out an extension based on extenuating circumstances.
- If you do not communicate with me before submitting an assignment late, the GCU late policy will be in effect.
- I do not accept assignments that are two or more weeks late unless we have worked out an extension.
- As per policy, no assignments are accepted after the last day of class. Any assignment submitted after midnight on the last day of class will not be accepted for grading.
- Communication is so very important. There are multiple ways to communicate with me:
- Questions to Instructor Forum: This is a great place to ask course content or assignment questions. If you have a question, there is a good chance one of your peers does as well. This is a public forum for the class.
- Individual Forum: This is a private forum to ask me questions or send me messages. This will be checked at least once every 24 hours.
“Parametric” and “nonparametric” are terms that are used interchangeably.
A Parametric Test is defined as
A parametric test is a type of hypothesis test used in statistics to generate data about the mean of the primary/original population. The t-test is performed using the students’ t-statistic, which is commonly used in that value.
The t-statistic test is used to test the underlying hypothesis, which includes the normal distribution of a variable. In this case, the mean is known, or is thought to be known. In order to find the sample from the population, the population variance is identified. The population’s variables of concern are thought to be estimated on an interval scale.
Non-Parametric Test Definition
A population distribution, which is what different parameters refer to, is not required for the non-parametric test. It is also a hypothesis test that is not based on the hypothesis itself. In the case of the non-parametric test, the test is based on differences in the median. As a result, this test is also referred to as a distribution-free test. The test variables are determined at the nominal or ordinal level. When the independent variables are non-metric, the non-parametric test is frequently used.
