Statistics deals with collecting, organizing, and interpreting numerical data. An important aspect of statistics is the analysis of population characteristics inferred from sampling.

Statistics are not used by scientists to do what?
Data Scientists can help determine whether or not that difference is significant enough to warrant increased attention.
The Gaussian distribution is the single most important distribution.
How many combinations are there for 4 numbers from 9 to 32?
there are altogether 24 numbers between 9 and 32.
by using nCr, 24C4 = 10626
How many combinations are there with 26 alphanumeric number?
It depends on how long would be the resulting string of character and if a character can be repeated or not
1) suppose a string of n characters and characters can be repeated
then for the first character one can choose 1 out of 26, the same for the second and so on then there are 26n solutions
2) suppose a string of n characters and none is repeated
This string would be less than 27 character long then n<27
for the first character one can choose 1 out of 26
for the second character one can choose 1 out of 25 (25 possible characters are left once the first is chosen)
for the third character one can choose 1 out of 24 (24 possible characters are left once the first and the second are chosen)
and so on
so there are 26x25x24x....x(26-n+1) solutions
What is the geographic grid used on the globe is based on the division of a circle in what degrees?
360 degrees from pole to pole and 180 degrees in circles parallel to the equator.
How do you create equations for the numbers 1-100 using four 4s for each?
ok so I can only think of the first 10, but here they are:
1= 44/44
2= (4/4)+(4/4)
3= ((4*4)-4)/4
4= (4(4-4))+4
5= ((4*4)+4)/4
6= ((4+4)/4)+4
7= (44/4) -4
8= (4*4/4)+4
9= (4/4)+4+4
10= (44-4)/4
What are the odds of rolling a seven with two dice fifty six times in succession?
The chance of throwing 7 with 2 dice is 1 in 6.
The chance of throwing 7 with 2 dice 56 times in a row is 1 in 656 ≈ 1 in 3.771 x 1043.
What is the probability of rolling an 11 with two dice?
You have 36 different possibilities (6 for the first die x 6 for the second die). Two of these are "favorable", giving you the desired result: both the combinations (6, 5) and (5, 6) work. Therefore, the probability is 2/36.

Claims Made Vs Occurrence Policies There are two primary forms of liability insurance policies - claims-made and occurrence policies. Most professional liability insurance, including directors and officers and employment practices liability insurance, is written on a claims-made basis.
An occurrence policy obligates the insurance company to pay for claims arising out of occurrences during the policy period regardless of when the claim is reported. The policyholder is covered for any incident that occurs during the term of the policy regardless of when the claim arising from the incident is reported to the company. In some situations the claim might be made many years after the incident occurred. This leads to uncertainty for both the insured and the insurer.
A claims-made policy protects an insured against claims or incidents that are reported while the policy is in force. Normally, a claims made policy provides coverage for acts occurring prior to the claims-made policy period. Coverage for acts occurring prior to the policy period is called "prior acts coverage," and the period prior to the policy period for which claims are covered is called the prior acts period. Prior acts coverage is usually only provided when a claims-made policy has been in force immediately prior to the current claims-made policy on a basis consistent with the prior policy. Prior acts coverage is defined as "full prior acts", covering acts occurring at any time prior to the current policy period, or is defined by a "retroactive date." When a retroactive date is used, prior acts coverage is provided from the retroactive date to the current policy period.
the answer in a multiplication problem.
In math, the product is the result of multiplication. For example the product of 3 times 2 = 6
To cause (a person) a painful loss of pride, self-respect, or dignity; mortify. (Humiliate)
To say that something is humiliating usually refers to something that is embarrassing .
I've never heard of primary vs. secondary sources ofreading, but I can provide an answer on primary vs. secondary sources of data.
A secondary source of data is data that was collected for a reason other than the task at hand. A good example is US Census data. Marketers might use census data as input into decisions. An example of application of this data is as follows. Suppose you want to distribute your product in the 5 most populated cities in the US. You could find this info from census data, and go about distributing your product in those 5 cities.
A primary source of data is data that is collected specifically for the task at hand, often via a market research study. For example, if you wanted to know what features of your product are most valued to buyers, you would design a market research study (i.e. questionnaire) to find that out. At the end of your study, you'd have the data to answer your question.

Note that there is quite a trade in used data. There's nothing wrong in this, provided all the relevant information about things like the purpose and reliability and possible sources of distortion of the old data are taken into account.
