Exams are coming up in a couple of days and I'm going to start studying for it. Although a lot of people may ask "How can you study for math?", actually you can and it's probably a wise decision TO study because then your awesome ! ;) But anyways, since I'm studying, might as well study with the whole class right ? Okie dokes.

These are the units we've covered so far:

Powers & Exponents


Basically the last unit we covered, Factoring, includes both "Polynomials" and "Powers & Exponents" (not so much Statistics though), so if you're able to do Factoring pretty good then you should be okay with the rest of the stuff.


Since "Statistics" is the odd one, I think I'm going to start with that:

Statistics is more the "languauge" of math rather then numbers. You just need to know what each one means. This is how i summarized the unit ... you don't need to memorize the definitions, just need to know what they mean ...


Population - is the entire set of items or group of people that data (information) can be taken from

EXAMPLE : If a teacher made a survey to see how many students would like to play basketball. The students are the "POPULATION"

Sample - is a selection taken FROM the population

EXAMPLE : If the teacher specifically picked Michele (me), and 5 or 6 other students. Those students selected would be the "sample"

Census - A survey that is based on the entire whole population, everything in the population is included

EXAMPLE : Canada has a census every five years where it surveys every adult in the country.

Representative Sample - A selection from a large group that portrays equally of the numbers of the large group

Bias - to apply either a negative or positive factor that could change an outcome, or that the whole population is not included.

EXAMPLE : Should teens be aware of the dangers of drinking and driving, to make our city a safer place ?
This question is bias, because it sort of pursways you to say "yes", because who doesnt want to be safe right ?
