Correlation! (Maybe... well the 6th letter is L at least).\n\nCorrelation basically describes the strength and direction of the (linear only) relationship between two variables or sets of observations. \n\nIt's a number between -1 and 1, and is denoted by 'r' or the Greek letter 'rho' (it looks like a 'p').  E.g. r = 0.87 \n\nI hope that's the kind of statistical symbols the crossword clue is referring to. \n\nGood luck with the crossword!

If you are using a sample set of data you can press stat/edit - then press enter/enter a list of numbers/ press stat again/move the arrow to calc/ select 1-Var stats/ press enter/press 2nd and then 1 (or L1)/ press enter.\n\nx bar = the sample mean\nSx = the sample standard deviation\nVariance = Sx squared

Actually, statistics books are notorious for being written in such a way that no normal human can understand them. The trick, generally, is trying to find a way to relate the problems to something you're interested in. For example, if you like basketball: one possible sampling distribution would be the number of free throws individual players make over a season. You could take a sample of, say, 10 of the players and find the mean and standard deviation. You could compute a 95% confidence interval with that information, which would allow you to say that you're 95% confident that the average number of free throws made by NBA players in a season will be between this number and that number. You could find the probability that a given player would make at least a certain number of free throws in a season by finding the z-score and looking it up on the normal probability distribution table, etc. If you're really struggling with the terminology, I recommend visiting your math help center on campus (most of them have one), or contacting a tutor.

If you discount the "sometimes Y" rule, then what about "rhythm"?

You can't apply statistics (to anything) unless you have a sufficient number of values to work with.  For example, if you took a poll of who people were going to vote for, if you only asked 5 people, you might not get an accurate representation - but if you ask 5000 then the margin of error gets smaller.  With molecules, there are millions of them.

I think you are talking about that book:\n\nOldrich Vasicek, "A test for normality based on sample entropy," Journal of the Royal Statistical Society, Series B, vol. 38, no. 1, pp. 54--59, 1976.\n\nI couldn't find a copy of this article, but it is easy to find a lot of other articles that are refer to it.\nHope, one of them will help you.\n\nAlso I strongly recommend to use a Citeseer scientific article database (2nd attached link). It usually contains a lot of information.

Used to set insurance premiums, the probability of getting into accidents based on your car type/age\n\nFor evaluating worker performance, ie you're on time 95% of the time or only 80%\n\nHow can you actually tell when two sets of data are different? Need statistics.\n\n A lot of jobs in stats!!

What you're looking for is the standard deviation.  If the data values are X and the mean is XBAR, then\n\nS.D. = sqrt{[SUM(X - XBAR)^2] / n}\n\nn is the number of data items, and SUM means to add up the squares of the differences between the data values and the mean.\n\nThe lower the standard deviation, the more tightly packed the data.  If the data is normally distributed, about 68% of the data will lie within one standard deviation of the mean, and 95% will be within two standard deviations.\n\n[Edit:  In light of the previous answers, I should add that the standard deviation is the square root of the variance.]

what type of statistics?

Standard deviation of a random variable X is defined as: \nό=√E((X-E(X))2) = √E(X2)-(E(X))2\n(the 2's of course are squares)

Statistics started out as a study of chance and the odds of games. \n\nThe original use for statistics was in predicting chance events. Jacques Bernoulli (1654-1705) wrote "The Art of Conjecture" which is the art of evaluating as exactly as possible the probabilities of things. \n\nGerolamo Cardana (1501-1576) Wrote the first book on probability, 'Liber de Ludo Aleae' which is about games of chance.\n\nRene Descartes (1596-1650) Believed that the universe had a mathematical structure. Much of his philosophy lies in that base. Although his stuff is more towards algebra than statsistics per se.\n\nRonald Fisher (1890-1962) In 1922 he gave a new definition of statistics. Its purpose was the reduction of data and he identified three fundamental problems.

statistics would be numbers and facts that relate to your topic (for example: # of states that allow gay marriage) \n\n"illustrating the numbers" just means that you put the numbers that you found (your statistics) into a graph or chart.

most statistics follow a pattern, whether it be linear, quadratic, or whatever. Once you have enough data to establish a pattern, you can accurately predict the remainder of the line.\n\nFor instance, you have a line that looks to be half a parabola. Once it starts going back up, you can be pretty certain of where it's going to be.

The exponential law of decay, the one with the lambda constant you speak of, is a statistical one. The lambda constant we use is taken from observing large quantities of atoms and seeing how may decayed after some time. For any one particular atom we can't be sure when it's going to decay, we can only speak of probabilities. Tfis is the meaning of the lambda - the probability of decay in a unit of time.\nThink of rolling six sided dice a couple million times. You can assume you'll get a '4' ON AVERAGE in 1 of 6 rolls, but there is no telling, in which rolls.
