What the difference between statistic as numerical fact and statistics as a discipline?

Answer 1

A statistic as a numerical fact refers to a single piece of quantitative data, such as the average income of a population. On the other hand, statistics as a discipline is the study of collecting, analyzing, interpreting, and presenting data. It involves a wide range of techniques and methods for making inferences and decisions based on data, such as hypothesis testing and regression analysis. In summary, a statistic is a single data point, while statistics as a discipline is the field of study that deals with data collection and analysis.

Answer 2

A statistic (as a numerical fact) is a value taken from a sample of a population. For example a summary of a political poll would produce many numerical statistics.

Statistics as a discipline involves creating and carrying out sampling designs, knowing how to analyze data, creating mathematical models for different processes, predicting future results, and optimizing systems. That is why statistics can by applied to any other field of study, any time you have to research, prove, or improve something the discipline of statistics is very valuable.
