How to Enable English Menus in Microsoft Office 2007

Link.


This is most useful for English Speakers who work on computers that are set in another language than English.
For example, I work overseas in Korea on a computer provided to me by my employer. The computer was installed with a Korean version of Microsoft Office. The toolbars and menus in Office were all in Korean, so it was a lot harder for me to navigate formatting. The steps below allowed me to change all the Korean in my Microsoft Office programs to English.
Step 1: Download the English Language Pack. (The hardest part of all this was finding the Language Pack, but I've made it easy for you by adding a safe download link below. It takes about 15 minutes to download) : http://msft-dnl.digitalrivercontent.net/msoffice/pub/X12-42421/X12-42421.exe
Step 2: Install the English Language Pack.
a. Select "Microsoft Office Language Pack 2007 - English" and click "Continue ."
b. Agree to terms and conditions and click "Continue."
c. Click "Install Now." (Installation will take around 2 minutes)
d. Click "Close."
Step 3: Click Start menu, point to All Programs, point to the Microsoft Office folder, point to the Microsoft Office Tools folder, and then click Microsoft Office 2007 Language Settings.
Click the Display Language tab. (first tab from the left)
Select English for both drop-down lists then click OK.
Last Step: Restart Computer, then Viola! Open Microsoft Word and you should see an English menu bar!

Statistical Moments

Link.

The mean and the variance provide information on the location and variability (spread, dispersion) of a set of numbers, and by doing so, provide some information on the appearance of the distribution (for example, as shown by the histogram) of the numbers.  The mean and variance are the first two statistical moments, and the third and fourth moments also provide information on the shape of the distribution.
For comparison, the
                           
is by definition is equal to zero.  (One might think of the mean as being that value of x that makes the above statement true, and consequently indicates where the individual numbers generally lie.
The second moment is recognized as the numerator of the variance
                        
which gives information on the spread or scale of the distribution of numbers.
The third moment,  is used to define the skewness of a distribution:
                             
Skewness is a measure of the symmetry of the shape of a distribution.  If a distribution is symmetric, the skewness will be zero.  If there is a long tail in the positive directin, skewness will be positive, while if there is a long tail in the negative direction, skewness will be negative.
The fourth moment,  is used to define the kurtosis of a distribution:
                              
Kurtosis is a measure of the flatness or peakedness of a distribution.  Flat-looking distributions are referred to as “platykurtic,” while peaked distributions are referred to as “leptokurtic.”
