What do both variance and the standard deviaton tell you about distribution?
How widely spread out, or tightly concentrated about the mean the observations are.
Why is it important to make sure the medical assistant program you choose is accredited?
You should investigate the accreditation of any school you want to attend for two main reasons. One, if you ever want to transfer credits, you might be disappointed if you attended an unaccredited school. The credits are useless at an accredited school. Two, an employer may only hire you if you have an education from an accredited institution. Don't get ripped off and make sure exactly what that accreditation means. Anyone can dream up an accreditation and make their school look legit.
Do not get ripped off by what I call 'scam schools'!
Since Variance is the average of the squared distanced from the mean, Variance must be a non negative number.

A stat or statistic is any mathematical function of measurements of some feature of a sample.
A sample is a selection of individuals that seem to represent the whole population from which the selection was taken. For example, if I have a list of all of the people living in Mumbai, India at this point in time I could select every 1000th name and that would form a sample of the people in that city. Now I could measure the weight in kilograms of each person in the sample.
There are many statistics I could calculate for this sample. Here are just a few:
1. I could find the smallest and largest. Each of these would be a statistic.
2. I could take the difference between the largest and the smallest. This would be a statistic.
3. I could calculate the average of the weights. This would be a statistic.
4. I could look for the commonest (most frequently observed) weight, known as the mode. This would be a statistic.
"Stat" is also a term used colloquially to men "immediately."
Difference between estimate estimator?
I think, the estimate is a numerical value, wile the estimator is a function or operator, which can be generate more estimates according to some factors. For example (xbar) is estimator for (meu), which can be various when the sample size in various, the value that will be produced is an (estimate), but (xbar) is estimator.

The value of 10 pfennige in the us?
It depends on its date and condition. The pfennig (= penny) was the equivalent of a cent in the old pre-euro German coinage system.
If its date is 1950 or later, it's worth anything from a quarter or so if circulated up to a couple of bucks if uncirculated.
If it's older than that, I'd suggest looking at a site such as www.sammler.com which covers most German coins. (aber achtung! Some of the site is in English but more is in German only.)
