You measured the heights and weights of a random sample of 100 NHL hockey players and found that the average weight was 190 pounds. However, suppose that the actual average for all 680 players in the NHL at that time was 192 pounds. In this case, the difference between your statistic and parameter would be:.

2 pounds

Explanation:

Parameters are numbers that summarize data for an entire population. Statistics are numbers that summarize data from a sample, i.e. some subset of the entire population.

So from the question above ,the paremeter is 192 because it covers the whole population while the statistics is 190 because it is gotten from the sample, hence the difference between them is 2.
