| bobbi | all means populatiom |
| limpus | I disagree, "all college students in Alabama" is the population. Their age is a parameter, is it not? |
| sumeet1982 | not sure. even my first reaction was "population" but i tend to agree with limpus. so is it population or statistic? more opinions please. |
| Carter | Population. Consider what we are measuring. We want to measure the age not the students. We're talking about data collection here. What is our data? Ages. A parameter of the population would be oldest, for example, or youngest. It is a characteristic that we could measure if we could include all the ages of all college students in Alabama. If it were a statistic, we would not be using the ages of all the students but instead, say, 5,000 students that attend college in Alabama. |
| chuong | We have both sides: A) students is population and age is statistics (exampe in sample of 100 randomly selected student, we have 10% of them have are over than 30 year old). B) age is population and student is statistics (example select the age of 20 from the rages of ages (0-100 years old) we have 48% is boy and 52% is girl). |
| soarer1 | "All" = Population |
| gulfa99 | Agree with limpus. |
| 2014 | Sample and statistics u can never collect of all students; so answer is straight |
| johntan1979 | My first reaction is parameter. Things like age, weight, height are definitely parameters or statistics. But considering the options available, the most viable answer is A, because B and C are worse choices. |
