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

How do you find out a median when there is only two numbers left?
If you need to find a median between two numbers, pick one of them arbitrarily.
In elementary terms what does 'hypothetical' mean?
It could mean to accept something without question by guessing; or it could mean of, to relate to, involving, or characterized by guessing. But it depends on how the word is used.
bamboozle means to trick someone
example: I bamboozled a lady in the park today
Why is variance a poor measure of risk?
One definite drawback is that it is usually derived based on historical data and does not take into account future factors.
What is a 130 digit number called?
Very big...
Scientists probably don't have an answer for something like that.
But, the highest known number, which is a number (infinity is not), is either google, google plex, or centillion.
How many different five digit numbers can you make using 1 2 3 4 6?
55
----------------------------------------------------------------------------------------------
From Rafaelrz.
You can make, 5! = 120, five digit numbers using 1,2,3,4 and 6.
How many words of 6 letters can be written if the first and last letters are both q?
6 letters minus your 2 unchanging letters leaves you with 4 letters of any combination of 26 possible characters each. That is 26^4 26 to the 4th. 456976 different combinations. If you understand permutations I used the simple repeatable permutations formula x^n.
What are the odds against drawing a 6 of clubs from a deck of cards on the third draw?
Since no information is given about the first two draws, they do not matter.
The odds against drawing a 6 of clubs from a standard deck of 52 cards is 51 in 52, or about 0.9808.
How do you findout ratio between 200000 500000 and 100000?
Find the GCF of the numbers and divide each by their GCF.
GCF(200000, 500000, 100000) = 100000
So the ratio is 2:5:1
What is a line plot with a range of 7 a minimum of 6 a median of 10 and modes of 8 and 11?
There are infinitely many possible solutions. The smallest set of numbers is
{6, 8, 8, 10, 11, 11, 13}
Another is {6, 8, 8, 8.3, 10, 10.65, 11, 11, 13}
When independent sample t test is used?
The Independent Samples T Test compares the mean scores of two groups on a given variable.
What is the least fraction you can write using the digits 3 4 and 5 what is the greatest explain?
I think the answer is 20/3 because 4*5=20 that's the biggest number those three numbers can make. the numerator is 3 and the denominator is 20.
Given (reworded a little):
- Length (L) = 4
- Must be an odd number is the same as saying it must end in an odd number
- Odd digits: 1, 3, 5, 7, 9 (nodd = 5)
- Even digits: 0, 2, 4, 6, 8 (neven = 5)
- n = Odd + Even = 10
- Odd digits can be repetitive
- Even digits cannot be repetitive
- Assuming we are not counting numbers that start with a 0, because they simplify into three digit numbers. (i.e., 0123 = 123)
First figure how how many four digit numbers in total you can have. This optional step gives you a check for your final answer, to make sure it makes sense.
I'll use square brackets to illustrate what can be in the boxes.
[n-1][10][10][10] = (9)(103) = 9000 total possibilities (this makes since because 9999 = 9000)
Because our number has to be odd:
[n-1][10][10][nodd] = (9)(5)(102) = 4500 total odd possibilities
Any number over 4500 does not make since for a final answer.
Break this into cases to simplify it.
Case 1: Number starts with an even number (remember if it starts with an odd number, we need to exclude zero). The first term will always be neven-1, but the next term, 0 is allowed, but you still have to remove the number you just used so it will also be neven-1.
EEEO => [neven-1][neven-1][neven-2][nodd] = 4 x 4 x 3 x 5 = 240
EOEO =>[neven-1][nodd][neven-1][nodd] = 4 x 5 x 4 x 5 = 400
EEOO =>[neven-1][neven-1][nodd][nodd] = 4 x 4 x 5 x 5 = 400
EOOO =>[neven-1][nodd][nodd][nodd] = 4 x 5 x 5 x 5 = 500
Case 1 total = 240 + 400 + 400 + 500 = 1540 possibilities
Case 2: Number starts with an odd number
OOOO => [nodd][nodd][nodd][nodd] = 5 x 5 x 5 x 5 = 625
OEOO =>[nodd][neven][nodd][nodd] = 5 x 5 x 5 x 5= 625
OOEO =>[nodd][nodd][neven][nodd] = 5 x 5 x 5 x 5= 625
OEEO =>[nodd][neven][neven-1][nodd] = 5 x 5 x 4 x 5 = 500
Case 2 total = 625 + 625 + 625 + 500 = 2375 possibilities
Add Case 1 and Case 2 totals up:
1540 + 2375 = 3915 possibilities
Check your answer against all odd number possibilities:
3915 < 4500, therefore our answer makes sense.
The answer is 3915 possibilities.
To check your work, try to find how many odd numbers have even numbers that repeat and subtract that from the total odd possibilities we found first. In this case though, this check is harder than the actual problem. You have to consider the EEEO, EOEO, EEOO, and OEEO cases. However the EEEO case breaks into three further cases, depending on which E is repeating.
How do you calculate mean average deviation?
The mean average deviation is the same as the mean deviation (or the average deviation) and they are, by definition, 0.

Impulse buying is the purchase habits of consumers who buy goods or services at the beginning point of contact. This behavior is influenced many of times by sale signs and advertisements at retail locations. The same behavior can be observed with e-commerce as well.
