b. Is the value of 85% a statistic or a parameter?

Accepted Answer

All right, hello, everyone. So this question says, a health magazine conducted an online survey asking, quote, should people reduce their daily sugar intake, end quote. Of the 1320 respondents who chose to participate, 78% answered yes. Is the value of 78% a statistic or a parameter? Option A says statistic. B says parameter. C says both, and D says none of these. So first, what is the difference between a statistic and a parameter? Well, first and foremost, both statistics and parameters are numerical values that describe a group. Now, the good news is that you can remember the difference between a statistic and a parameter by noticing the first letter of each word. And what I mean by that Is that statistic, for example, which starts with an S, is a numerical value that describes a sample. And recall that a sample is only a subset of a larger population. Parameters on the other hand, that starts with a P. Is a numerical value. That describes an entire population. So going back to the given example. Here, 78% is derived from the people that answered or chose to participate in the online survey. So here, we're not talking about the entire population, rather, we're talking about a subset of people that chose to respond to the survey. So therefore, 78% is a statistic making A the correct choice. And there you have it. So with that being said, thank you so very much for watching, and I hope you found this helpful.
