Statistics

I'm not sure what you're asking, but if you mean : given a number (lets say 100) find 25% of it.

For this, you could easily (since they are compatible) reduce it. 25% is equal to one fourth.

One fourth of 100 is 25.

If it is something like...10% of 30, DO NOT SAY IT IS 10. THE ANSWER IS NOT TEN.

Ten percent in decimal form (move the decimal over/left two spaces) is 0.1

0.1 multiplied by 30 is 3.

You could also use proportions, 10% = 1/10 simplified version of 10/100

the unknown number is the value out of 30. Use x as the variable.

The equation is 1/10=x/30 what you do is multiply across with the PRESENT numbers, then divide with the other one. Never multiply vertically or horizontally.

30x1=30 then 30\10 = 3

So, 10% of 30 is 3. (:

Secondly, if you have two numbers, like 50 and 100, and you need to find what percentage 50 is OF 100, you use proportions.

Since percentage is a number in a ratio to 100, it is a value over 100.

x/100=50/100

50x100 = 5000 5000/100=50

50/100 = 50%

It depends on the context.

In geometry, a median is a line from a vertex of a triangle to the mid-point of the opposite side.

In statistics, the median of a set of data is the value such that it is larger than half the values in the data set, and smaller than a half.
Median means the number that comes up in the middle. An example would be:

here are your numbers 1,2,3,4,5 your median would be 3. You have to have your numbers in order before doing median.

If the sequence you are given is not ordered, you must order it before finding the median. Thus for the sequence 2,1,5,3,4 the median is 3 (and not 5).

Vesting is an issue in conjunction with employer contributions to an employee stock option plan, or to a retirement plan such as a 401(k), annuity or pension plan.

A vested right is "an absoluted right; when a retirement plan is 100% vested, the employee has an absolute right to the entire amount of money in the account." It is a "basic right that has been granted, or has accrued, and cannot be taken away. Example: one's right to a vested pension."

There is two type of vesting, graded and cliff.

Graded means you get a certain percentage of your employer contribution each year, until you're fully vested. A five year grated plan would mean that you would have access to 20% of your employer contribution the first year, 40% the second, and so on.

Cliff means that you have no acces whatsoever, until your worked your vesting period. A five year cliff vesting period means you have no access to the employer contribution, until your worked that full 5 year period.

No. In proper English usage, "this Friday" refers to this coming Friday and "next Friday" refers to the Friday after that.

There are plenty of agreements/disagreements on this subject. These opinions come from scholars in the language. What gives?

There are 2 main methods for fixed point iteration, the Newton-Raphson method, and the Secant method.

This method uses the formula, xn+1 = xn - f(xn) / f'(xn),

where xn is the initial point, f(xn) is the value of the function at that point, and f'(xn) is the value of the differentiated function at that point. Plug all these values into the above equation to get xn+1, which then becomes the next initial point. Repeat until you get a point within an acceptable degree of error.

the formula for this method is, xn+1= xn - (f(xn)(xn - xn-1)) / (f(xn) - f(xn-1)).

With this formula you do not need the differentiated form of the function, making this a better method than the N-R for functions difficult to differentiate. However you do need two initial points for this method to work (xn and xn-1). Again just plug the appropriate values into the formula to generate the next point approximation.

NB: with both of these methods be careful which initial point you choose, especially with the N-R method, as depending on the function the approximation iterations can go out of control and zoom away from the point you're trying to find.

Also, a note on errors, you can sometimes get a better approximation by fiddling with your function a bit and reducing the amount of calculations needed. For example if you have two equivalent functions, but one takes 3 calculations to get a value and the other takes 6, the latter takes more work and will generally give a bigger error than the previous. Usually this error increase is only marginal, but depending on the function and the values used, the potential error can be huge. This only needs to be taken into account though if you want extremely accurate results. (Things to look out for if trying to reduce error: subtracting near equal numbers, dividing by a small number or multiplying by a large number, cancellation of significant figures)
