Statistical data refers to the outcomes or observations that occur in scientific experiments or investigations. It is the raw information from which statistics are created. Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data. Statistical data can be qualitative or quantitative. Qualitative data refers to non-numerical data such as gender, education status, and marital status, while quantitative data refers to numerical data such as age, height, and weight. Statistical data can be collected through various methods such as surveys, experiments, and observations. Once the data is collected, it can be analyzed using statistical tools such as mean, median, mode, variance, and standard deviation. The two main areas of statistics are descriptive statistics, which summarize data from a sample using indexes such as the mean or standard deviation, and inferential statistics, which draw conclusions from data that are subject to random variation. Statistical data is used in various fields such as science, industry, and social sciences to make decisions in the face of uncertainty.
