CST Practice Review

My Wonderful 8-2's ::waves::
The time has come!
CST is just around the corner!
You have learned everything you needed to know and it's a few days before the exam!

Please click on any link to your left <-----, to practice anything and everything you need to ensure your success!

**note: You can click on the CST link, which will take you to a list of standards. That is the best way you can practice and review specific concepts that you are unsure of!

I would highly advise you to take about 20-30 minutes of your time (trust me, that's not a lot), to review, review, and REVIEW!

Reminders:
*review your practice packets
*get plenty of rest (sleep at least 8 hours)
*eat breakfast
*stretch
*have CONFIDENCE.

My dear students, you are bright. You are capable. Please take your time...use the post-its, read EVERY single problem carefully, and think LOGICALLY!

Mean, Median, Mode, Range, Outlier

I love this topic. It's very simple and very easy to work with. The only concept that is difficult is the "MEAN."

The most important thing you need to remember is to ALWAYS put the numbers in order from least to greatest.
...

I know I sound like a broken ____, but you MUST put the numbers in _____ (order)!

Let's get started:

MEAN: the MEAN is..very mean. It makes you do a lot of calculations! You need to add up ALL the numbers first, and then divide that sum by how many numbers you added.

MEDIAN: the MEDIAN is the MIDdle number. As you have the numbers in order, you need to work your way from the outside of both ends and find the middle number. Then, BAM! You are done! The only tricky part is when there are TWO middle numbers. When there are TWO middle numbers, you must..find the MEAN (add the two numbers, and then divide the sum by 2).

MODE: the MODE is the number that comes out the MOst. There can be more than one mode, or no mode at all! The number that comes out the MOst is the MOde.

RANGE: think: Home on the Range. Since you should have the numbers in order, all you do is subtract the biggest number of the group to the smallest number of the group.

OUTLIER: the OUTLIER is an OUTcast. It sticks out from the rest of the "crowd." When the outlier is lower than the rest of the numbers, the mean becomes lower. When the outlier is higher than the rest of the numbers, the mean becomes higher. Outliers do not affect the median nor the mode. Isn't that nice?

That's it! Not too shabby?

Again. I know I sound like a broken _____, but always remember...to put the numbers in ___.

Have fun reviewing (click on the links on the left side of the screen to practice)!

Circumference is the distance around a circle (perimeter).
A great way to remember this formula is by singing the "Twinkle Twinkle Little Star" song:

"Twinkle twinkle little star,
Circumference equals two pi r."


Formulas: πd or 2πr

remember: the radius is half the diameter, which is why EITHER of these formulas will work! Pretty groovy?
------------------------------------------------------------------------------------------------
Area is the space covered inside the shape, in this case, the circle.
We can use this rhyme to help us remember the formula:

"Fuzzy Wuzzy was a bear,
Area equals pi r squared."

Formula: πr^2

*Be careful. You must be able to correctly identify the diameter and radius and substitute the values into your formulas.

Simple Interest

Think: I PARTY!

I = Interest
P = Principal
R = Rate
T = Time (in years)

I = PrT

In order to find the simple interest, multiply the principal (the original amount), with the rate and time. Do NOT FORGET to move over the percent (rate) twice to calculate using a decimal.
