How do You Identify Whether if a Number is a Parameter or Statistic?

If you want to figure out whether a number provided is a parameter or a statistic then asking yourself the following questions are great way to understand.

Does the number give interpretation of entire population where it is accessible to reach out for each and every one of the member for data collection?

Will it be reasonable for me to data collect for this number from every member of the population within given time frame or not?
The result will be in yes or no to these questions in case the answer to both of these questions is yes then the number is most likely going to be parameter. Parameters could be used for small population of data collection because whole of the population could be easily summarized in parameter.

The no to any of these questions means the number is statistic.
