Statistical analysis is a method used to analyze and interpret data in order to make informed decisions or draw meaningful conclusions. It involves using mathematical techniques to summarize and interpret data sets, identify patterns, test hypotheses, and make predictions. Statistical analysis can be applied in various fields such as psychology, economics, biology, and sociology to analyze research findings and draw valid conclusions. Common statistical techniques include descriptive statistics, inferential statistics, regression analysis, hypothesis testing, and correlation analysis. Researchers use statistical analysis to gain insights into the relationships between variables, make predictions, and support their research findings with empirical evidence.
