Statistical analysis means investigating trends, patterns, and relationships using quantitative data. It is an important research tool used by scientists, governments, businesses, and other organizations.

In this study, various statistical analysis methods are discussed, including normality test, one-group mean and independent two-group mean difference test, dependent or before-and-after group mean difference test, one-way analysis of variance (ANOVA), repeated-measures ANOVA, chi-square test, Fisher’s exact test, correlation analysis, linear ...

This article covers many statistical ideas essential to research statistical analysis. Sample size is explained through the concepts of statistical significance level and power. Variable types and definitions are included to clarify necessities for how the analysis will be interpreted.

Statistical methods involved in carrying out a study include planning, designing, collecting data, analysing, drawing meaningful interpretation and reporting of the research findings. The statistical analysis gives meaning to the meaningless numbers, thereby breathing life into a lifeless data.

to power analysis and the interpretation of findings aris-ing from studies with small sample sizes. We highlight the use of external information to inform estimates of true effect size and propose what we call a design anal-ysis—a set of statistical calculations about what could happen under hypothetical replications of a study—that
