Non-Parametric Tests: Chapter-IV- Business Research MethodsDayanand Huded
油
The document consists of non-parametric tests in Business Research Methods. The chapter includes other details such as Meaning, Advantages; The Chi-square Test, The Sign Test, The Mann-Whitney U Test (in case of Large Sample only), the Kruskal Wallis H Test (in case of Large Sample only), the Runs Test for Randomness (in case of Large Sample only), The Wilcoxon Matched Pairs Signed Ranks Test (in case of Large Sample only).
Chi-Square Tests: 1. Chi-Square Goodness-of-Fit Test
Used to determine if observed frequencies differ significantly from expected frequencies.
The test statistic (2) is always non-negative because it is based on squared differences.
A large 2 value indicates a significant deviation from the null hypothesis, so the rejection region lies in the right tail.
2. Chi-Square Test for Independence
Used to determine if two categorical variables are independent.
Again, the 2 statistic is always non-negative, and a large value suggests dependence between variables.
The sign Test: The Sign Test is a non-parametric statistical test used to evaluate the hypothesis about the median of a population or to compare paired data, particularly when the assumptions of parametric tests (like normal distribution) are not met. It is based solely on the signs of the differences between paired observations, making it distribution-free.
The Mann-whitney U Test: The sign test for comparing two population distributions ignores the actual magnitude of the paired observations and thereby discards information that would be useful in detecting a departure from the null hypothesis.
Kruskal Wallis H Test: The Kruskal-Wallis H Test is a non-parametric statistical test used to determine whether there are statistically significant differences between the medians of three or more independent groups. It extends the Mann-Whitney U test to more than two groups.
Run Test for randomness: The various tests discussed above are based on the assumption that we are dealing with random samples, i.e., samples chosen without bias. However, there are many situations in which this assumption is not justifiable. This is particularly true when we have little or no control over the selection of the data.
Wilcoxon mathced paired-sign-rank: When you can determine both direction and magnitude of difference between carefully matched pairs, use the Wilcoxon matched-pairs test. This test has excellent efficiency and can be more powerful than the t-test in cases where the latter is not particularly appropriate.

I'm implementing Twinzie (trained AIs that can interact with each other, discover win/win opportunities without disclosing the session directly to the respective users) in Valuable -- buyer/seller negotiation without exposing the seller's item before a mutually agreeable price can be proposed.油 Also starting to get traction for same model with the consulting firm I work with, where they have Twinzies of each of the participants of an experience do private 1-1 sessions to create their own Twinzie, and when group sessions are conducted, ideas in the session can get a score on whether they truly resonate with the participants' gestalt intentions or whether the idea might do violence to someone's intention...without revealing those intentions or outing people. Even in a session with three or four people, the live scoring doesn't provide any real sense of who might not like the idea. It just gives the room a sense of true alignment or a sense that something hidden might need to be addressed.

A scattered radiation survey in a radiology department is an essential process for ensuring radiation safety and compliance with regulatory standards. Scattered radiation, which is secondary radiation deflected from its original path after interacting with a patient or other objects, poses a potential hazard to healthcare professionals, patients and general public.
Protection for Healthcare Workers and General Public: Scattered radiation surveys pinpoint areas where scattered radiation levels are highest. This helps in identifying workspaces or equipment where additional shielding or protective measures may be needed.
Since prolonged exposure to scattered radiation increases the risk of conditions like cancer and cataracts, surveys help to ensure that exposure stays within safe limits, adhering to regulatory standards and minimizing long-term health risks. Survey helps to protect Workers and General Public.
Radiation Survey data for safety improvements: The data collected in these surveys allows the X-ray department to make informed decisions about room layout, equipment placement, and workflow adjustments to further reduce exposure.
Surveys help identify where lead aprons, thyroid shields, and lead glasses are most effective, and when extra protective barriers or shields might be necessary for staff safety.
Radiation Survey for image quality: Clear, high-contrast images are essential for accurate diagnoses. When scattered radiation is minimized, the images are of higher diagnostic quality, helping radiologists detect abnormalities and make precise evaluations.

We use the modal verb Can to express that we
know how to do something.
The negative form is cant or cannot (more
formal).
Can and cant are always followed by a verb in
the infinitive.
