Statistical significance

statistically significantsignificantsignificance level
In statistical hypothesis testing, a result has statistical significance when it is very unlikely to have occurred given the null hypothesis. More precisely, a study's defined significance level, denoted by \alpha, is the probability of the study rejecting the null hypothesis, given that the null hypothesis were assumed to be true; and the p-value of a result, p, is the probability of obtaining a result at least as extreme, given that the null hypothesis were true. The result is statistically significant, by the standards of the study, when . The significance level for a study is chosen before data collection, and is typically set to 5% or much lower—depending on the field of study.

Interpersonal compatibility

Interpersonal compatibility or interpersonal matching is the long-term interaction between two or more individuals in terms of the ease and comfort of communication.


In statistical hypothesis testing, the p-value or probability value is the probability of obtaining test results at least as extreme as the results actually observed during the test, assuming that the null hypothesis is correct. The use of p-values in statistical hypothesis testing is common in many fields of research such as physics, economics, finance, political science, psychology, biology, criminal justice, criminology, and sociology. The misuse of p-values is a controversial topic in metascience.

Fitness modelling focuses on displaying a healthy, toned physique. Fitness models usually have defined muscle groups. The model's body weight is greater due to muscle weighing more than fat; however, they have a lower body fat percentage because the muscles are toned and sculpted. Fitness models are often used in magazine advertising; they can also in some cases be certified personal fitness trainers. However, other fitness models are also athletes and compete as professionals in fitness and figure competitions. There are several agencies in large markets such as New York, London, and Germany that have fitness modelling agencies.
