Population vs parameter in statistics
WebParameter: A population mean. For this population of students at a small college, the mean amount of financial aid is $1,500. Statistics: Sample means that vary. In the example, $2,087.50, $1,325.00, and $687.50 are all statistics that describe the mean amount of financial aid received by a sample of 8 students. WebParameter vs. Statistic. Parameters and statistics have a lot in common. They both tell something about a group, such as that 20% of M&Ms are red. But the main difference is who and what are they describing. Parameters refer to the whole population. Statistics refer to the portion or the sample that was studied in a study.
