Statistics is a subfield of mathematics that is involved with the gathering, examination, interpretation, and presentation of large quantities of numerical data. Large-scale numerical data collection and analysis, particularly with the aim of determining proportions in the whole from those in a representative sample, constitute the activity or science of statistics.

Statistics is frequently used to understand natural events. When applying statistics to a scientific, industrial, or social problem, it is typical to start with a statistical population or a statistical model that will be evaluated.

By using our comprehensive online statistics calculator, you can determine the mean, median, mode, standard deviation, variance, or correlation coefficient of any given dataset.
