Okay! I'm going to be the teacher and you have to listen to me! Finally! This term in math my class learned about a few things. In order they are: The Measurements of Central Tendency (Otherwise known as Mean, Median, Mode and Range), Square Roots, Percentages, and Proportions. I will lead you through the process. So good luck! (Oh, and please give me a passing grade! Or a good grade, and example would be a 80%)

First, I have to like to my scribe post, so here it is...um..OK OK! YOU GOT ME! I didn't finish it! Don't kill me! I'm SOOOO SORRY!


 * Ahem* Next, I have to link to my growing post, so here IT is:

Finally, I have to show you my BOB (Blogging on Blogger) So here it is:

Finally! On with the show! This is it!

__**Mean, Median, Mode**__ Ok! I'm gonna start off with the Mean, Median and Mode. Mean, Median, and Mode are three of the Measures of Central Tendency. What more can I say? Firstly, you've got to know how to count properly. Secondly, you should know what the word "middle" means. And lastly, you MUST know your numbers! Haha! Just Kidding! Of course you know your numbers! Er...I hope...please do! For the sake of my grade...er and my pride. But seriously, once you know this you'll be able to figure out the following questions. But first, I must teach you the procedures.

1 3 2 4 6 5 <---These numbers are called the RAW DATA. The RAW DATA is what you should first notice. It doesn't matter which or how many numbers there are. With these numbers, the first thing you should ALWAYS do, ALWAYS, is to put them in NUMERICAL ORDER! NUMERICAL ORDER is when you organize the numbers so that the least amount goes first, getting higher and higher, and, you know what I mean...If you don't put it in NUMERICAL ORDER, I will take Mr.Penner's whistle and blow it in you're ear! Er..ears..

1 2 3 4 5 6 <---This is NUMERICAL ORDER.

Note to parents: If you do not put the numbers in numerical order, you'll never get the right answer for anything IN THIS UNIT!

The next thing to do would be to find the Mean. To do this, you must add all the numbers together. What you'll end up with is called the "Sum of All Data".

1+2+3+4+5+6=22<---Sum of All Data.

Once you've found the Sum of All Data, you divide it by the total numbers you have. In this problem, we have 1...2...3...4...5... 6....6 numbers. So you divide 22 by 6 to get the Mean.

1+2+3+4+5+6= 22 22/6=3.66 (repeat) <---Mean.

Note to parents: Mean means Average.

After you've figured the Mean, the next thing to figure out would be the......MEDIAN! Now, to find the median, you must have your RAW DATA set in NUMERICAL ORDER! Otherwise, the answer you end up with will be completely wrong, and I'll have no choice than to whistle in your ears with Mr. Penner's whistle! Um...washed of course (Like I want Penner germs! EWWW!). HAHA! You don't really want to get this easy task wrong. It's pretty straight forward: In NUMERICAL ORDER, find the middle number. In this case, there is 1 middle number. But if you run into 2 medians in a problem, the best thing to do would be to add them together and divide by 2.

Note to parents: Median means "middle". If you remember this fact, you'll never get the wrong answer when it comes to finding the median.

Now, there is one more thing to find. *Drum roll* The Mode! *Clash! *Hurray!* to figure the mode out I'm going to refer back from the top of this page....KNOW YOUR NUMBERS AND KNOW HOW TO COUNT! That's all you need to find the mode. That's all.

Note to parents: The mode is the number that shows up the most. It doesn't matter what number it is. Oh! Also, you can have a mode, or modes, or not, so keep your eyes peeled in case there isn't one.

Well that's how you figure out the Measures of Central Tendency, well the main ones anyway. Wait! Don't assume that I'm going to let you go so easily! We're not even half way through my lecture! If you learned something, show me. Here is a question about Mean, Median and Mode.

Question: What is the mean, median and mode for this set of data: 3 3 6 12 17 25 40

Answer for Mean, Median and Mode question

__**Percentage**__ Aww man...! This is getting too long!!! Oh well...long story short, the word percent means, "Something out of a hundred". To narrow down further...in French, "per" means out of and "cent" means a hundred. So naturally, percent means "something out of a hundred"....Is it just me or am I sounding a bit like Mr. Cann? Er....or maybe it's Mr.Rammy....AHHHH! NOT THE FRENCH!!!! MY EYES!!!! MOI(my) ACCENT!!!!


 * Breath! Breath!* Well, anyway, to find the percentage of a number, you always have to remember that the number that is the whole is 100%. For example, if you say that 45 is the whole number (100%), and you're looking for 50%, this is what you do.

__Make a word ratio!!!__

Note to Parents: When finding relationships between numbers........do the same thing for both the top and bottom.

QUESTION!

Question: Is taking 15% off a given number then an additional 10% off the reduced price the same as taking 25% off the original price? Why or why not?

Answer for Percent question

__**Square Roots**__ Aha! Now I'm going to teach you about Square Roots! Too late! You can't run away from my lectures! Muahhahaha! *Ahem Ahem* Think about "perfect squares" when it comes to square roots. The perimeter of a 4 by 4 track field would be 16. The Square Root is the number that is multiplied by itself to get a whole number. So if I asked what the whole number's square root was, all you needed to do was to find the number in which you divide the whole number by to get itself.


 * Parents stare. Mom blinks. Dad scratches his head. Sister stares blankly into space. People just stare at my family weirdly. SOMEONE nods their head understandingly*

Okay, okay. I'll explain more thoroughly. Say, you wanted to know the square root of 49. Well, there is the easy way (stares at calculator), and there's the way that makes you think (stares at paper and pencil). And don't think I don't know what you're thinking. It's something along the lines of this: "Oh, great. There's an easy way. Let's pick that so we could get this over with and go home." Too bad! I'm not letting you get away so easily! I'm going to teach you how to.......FIND THE SQUARE ROOT OF A NUMBER WITHOUT USING A CALCULATOR!!! *dun dun dun duhhhhhh* *MUAHAHAHAHA!*

Thanks to Mr. Hanley (points to the tallest MATH/GUY teacher in the ROOM/SCHOOL), I was able to completely understand the steps of finding the square roots of numbers. Kudos to you Mr. Hanley.

To figure out the square roots of whole numbers, you'll need to make a "perfect square chart". To make this chart all you really need to do would be this: 1x1=2.....2x2=4.......3x3=9......4x4=16....and so on. The numbers you get as an answer, (ex. 4x4=16) is the "perfect square", and the numbers that are multiplied by themselves to get the "perfect square" is the "square root". Here are tips you should be aware of when dealing with square roots.

-Perfect square chart -knowledge of multiplication -knowledge of division

Now here's a demo problem. Find the square root of 61.

The first thing you should do is to look in your perfect square chart, and see where the number lies between. In this case, 61 would land between 49 and 64. 7x7=49.....7? X7?........8x8=64 to find, the class learned how to find a fraction. To find that fraction, you'll have to take the first perfect square number and list all the numbers that are listed between itself and the next perfect square number.

49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64 to find the denominator of the fraction; subtract the least amount, from the greatest amount. 64-49=15 <---denominator.

To find the numerator of the fraction, count the many numbers it takes until you reach the number which you are trying to find the square root of. In this particular problem, the numerator would be...1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12...12.

And there you have it. The square root of 61 is.....7 12/15.

QUESTION!

Question: What is the square root of 45?

**Answer for Square roots question**

Proportions......Proportions, proportions, proportions.....They drive me up a wall. Well, not really. I'm going to speed up the process on this one as well because I feel like this whole report is too long for my liking....and besides, I WANNA GO HOME!!!
 * Proportions**

Two major proportions that I learned in math are: Finding relationships (shown when dealing with fractions), and XKY charts. I'll skip how to figure out problems by using the different proportions because your smart people and I don't wanna waste your time....hopefully....or I'll show you in class or something...maybe i'll teach you at home....

ANYWAY! QUESTIONS!

Question 1: Mika Uchiha scored 6 goals in 8 minutes. If she keeps scoring at this rate, how many points will she score in 48 minutes?

Answer for question 1

Question 2: If Mika's brother, Sasuke, scored 12 baskets in 8 minutes and then another 3 in 2 minutes, how many baskets in how many points did he score? If he kept scoring at that rate, how many points did he score in 50 minutes?

Answer for question 2

TAADAAA!! I'M DONE! OK WE CAN GO HOME NOW! (I hope you learned something 'cuz i'm gonna quiz you at home! MUAHAHAHA!! FEEL MY WRATH! *Mom grounds me and I go cower in a corner hoping for my freedom*)
