Name___Alexis Montgomery_________________________Sect_____210_____ Population, Parameter, Sample, Statistic Population : The population is what we want to learn about. Most of the time it is large. Sample: The set of individuals, items, or data that is taken from the population and surveyed. Parameter: Describes the population; most of the time we do not know this number. We usually estimate. Statistic : Describes the sample. We use this along with margin of error to estimate the parameter. __________________________________________________________________________________ The following is a quirky example. Suppose I am an ant. Yes I said ant and not aunt. As a matter of fact I am the queen ant. Lately I have notice that my worker ants have been acting somewhat discontent with their jobs. I decide that I want to find out about job satisfaction in my hill. There are some many ants in my hill that it would be impossible for me ask all of them. So instead I ask 200 how they feel. I find that 99% of them are dissatisfied and would rather spend their time eating at the picnic rather than carrying the food back to me.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
