Statistic vs Parameter
Why do we use Statistics ?
Statistics is used to estimate the population parameters. For large size population, we use the statistical values to draw conclusion from the sample which gives an overview of the population.
Can parameters and statistics have the same numerical value?
Yes, parameters and statistics can have the same numerical value, but it depends on the context and how they are defined.
Why are Greek letters used to represent parameters and Roman letters for statistics?
Greek letters are frequently written in the formulas to show simple value or a variable relating the whole population of the problem. Roman letter is used for statistics because they are a rational quantity that is calculated from a set of samples or data
Can parameters change over time for the same population?
Of course, parameters can change over time for the same population if there is a change on the characteristics of the population them self. For instance, the average income of sample people could goes up or down during the years due financial matters or demographic shifts such as type of migration or births.
