This article provides information on statistical tests, including when to perform a test, how to choose the right one for your data and what assumptions are made by statistical tests. It also explains the difference between quantitative and categorical variables, as well as discrete and continuous variables.
Statistical tests are used in hypothesis testing to determine whether a predictor variable has a statistically significant relationship with an outcome variable or estimate the difference between two or more groups. They assume a null hypothesis of no relationship and calculate p-value to see if observed data falls outside of predicted range.
A statistical test works by calculating a test statistic that describes how much the relationship differs from the null hypothesis, then calculates p-value which estimates likelihood of observing this difference if there is no real relationship.
You can perform statistical tests on data collected through experiment or probability sampling methods as long as sample size is large enough and meets certain assumptions such as independence, homogeneity, normality etc.
To choose the right one you need to know your data's assumptions and types of variables (quantitative/categorical) being dealt with. Parametric tests have stronger inferences but stricter requirements while nonparametric ones make weaker inferences but don't make many assumptions about data distribution.
Versatility refers to the capacity to adapt and excel in different roles and environments, showcasing a wide range of abilities and competencies. In its essence, versatility entails the ability to embrace change willingly and the capability to adjust to diverse circumstances effortlessly.
