In statistics, we differentiate between a population and a sample:
-
Population: The entire group that you want to draw conclusions about. In this case, the population is all the players in the softball league.
-
Sample: A subset of the population that is selected for the survey or study. In this case, the sample consists of the 45 players Maritza asks about their involvement in basketball.
Now, let's summarize the information:
-
Population: The entire group of players in the softball league.
- Size of the Population: 225 players
-
Sample: The subset that Maritza selected to ask about basketball.
- Size of the Sample: 45 players
Summary:
- Population: All 225 players in the league
- Sample: 45 players selected by Maritza
- Size of Population: 225
- Size of Sample: 45
This distinction helps us understand that while Maritza is only asking a few players (the sample), she is trying to infer information about the larger group (the population).
