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

Why is analysis of residuals important?
An analysis of the residuals can be used to check that the modelling assumptions are appropriate.
Rolling three dice what is the probablity of obtaining different outcomes?
Depends if the dice is bias then you an not have an answer if it is fair then you times 6 by 3 which = 18 so if you want three different outcomes then 3/18 which is simplified to 1/6 of a chance!
It means pleasing someone else to avoid conflict like war
Can people with double jointed knees have more trouble doing splits?
The concept of being "double jointed" is a myth as all humans (unless there is some form of birth defect) have the same number of joints. The term "double jointed" really means that the person has a wider range of motion than the average person, which is known as hypermobility. So a person who is more flexible would most likely have an easier time doing splits.
How many 5 digit numbers can be made with the numbers 1 2 0?
The first digit can by selectd in one of two ways, since a number starting with zero would not be a 5-digit number. After that, each of the other four digits can be selected in 3 ways. So the number of 5-digit numbers is
2*34 = 162
What is the mean median modes and range of 11 15 22 10 6 14 12 14?
6, 10, 11, 12, 14, 14, 15, 22
mean: 13
median: 13
mode: 14
range: 16
What is the best way to determine if two variables are related?
The easiest way is to draw a scatter plot.We are assuming here that the variables are supposed to have a relation, for ex height and weight of people.
What is distribution in species?
Species distribution is the manner in which a biological taxon is spatially arranged. Species distribution is not to be confused with dispersal, which is the movement of individuals away from their area of origin or from centers of high population density. A similar concept is the species range. A species range is often represented with a species range map. Biogeographers try to understand the factors determining a species' distribution. The pattern of distribution is not permanent for each species. Distribution patterns can change seasonally, in response to the availability of resources, and also depending on the scale at which they are viewed. Dispersion usually takes place at the time of reproduction. Populations within a species are translocated through many methods, including dispersal by people, wind, water and animals. Humans are one of the largest distributors due to the current trends in globalization and the expanse of the transportation industry. For example, large tankers often fill their ballasts with water at one port and empty them in another, causing a wider distribution of aquatic species.

What is the probability of throwing a sum of 8 with 2 dice in nine throws?
The first thing to do is isolate how many ways there are to get 8 from two dice. These possibilities are:
2,6
3,5
4,4
5,3
6,2
so there are 5 possibilities. The probability of each of these combinations is (1/6)2 or 1/36, so the probability of getting 8 in one throw of 2 dice is 5/36
For 9 throws, it is easier to calculate the probability of never getting 8. This is (1-probability of getting 8)9. (1-5/36)9 = (31/36)9 which is 0.26033. So the probability of getting an 8 somewhere along the line is 1-0.26033 or 0.7397
Is the central trendency measured in Mean or Median?
Both are measures of central tendency. But, the mean has mathematical properties that are better understood.
What is the mode for the numbers 100 90 85 85 70 95?
85 appears more than any number, so it is the mode.
http://dictionary.reference.com/browse/flurry. It states that flurry means "a light, brief shower of snow"
It means unable to be described. Kind of like "it is so beautiful I can't find words for it." It means that it is overwhelming, or awesome (NOT in the sense of "awesome, dude" ... in the sense of awe-inspiring). Things can be indescribably beautiful, or indescribably horrific. ... Hopefully not both. :) Things can also be indescribably good or bad or black or deep... anything where the scale is just too gigantic or unbelievable for words. :)
