"Determine whether the statement is true or false. If it is false, rewrite it as a true statement.

A statistic is a numerical description of a population characteristic."

Accepted Answer

Hi, and welcome back, everyone. Our next question says, determine whether the following statement is true or false. If it is false, rewrite it to make it true. And our statement is a parameter is a numerical description of a sample characteristic. A false, a parameter is a numerical description of a population characteristic. True. The statement is correct. False. A parameter is a numerical description of a sample statistic. Or false, a parameter is a qualitative measure. So when we think about parameters and statistics, we're thinking about things like Um, you or Sigma. Etc. And these are all descriptors of characteristics of a population. So, our answer is going to be choice A. Our statement is false, because it's not a numerical description of a sample characteristic, but a description of a population characteristic. So, it is a numerical description, but the keyword there is population. So, remember, the sample is a smaller group drawn out from a larger population, and we hope that it will be characteristic of our population, and we can study it and look for its own. Characteristics and use them to approximate or compare to the parameters, but the parameter itself refers to the population. So choice B incorrect because our statement is false. Choice see, well, our statement is false, but again, we're referring to population. Not sample. And when we look at that word statistic, that is what we describe, or what we use when we're talking about properties of a sample, a sample statistic, whereas a population characteristic as a parameter. So to see the wrong answer, even though statistic is the correct word to pair with sample. And in choice D false a parameter is a qualitative measure. This is incorrect. A parameter is a numerical description. So just write numerical. So, once again, we have a statement to determine true or false, rewrite it if false, and our statement that a parameters and numerical description of a sample characteristic is choice a false, and we would rewrite that as a parameter is a numerical description of a population characteristic. See you in the next video.
