It means that no correlation exists between those two variables. If you know anything about statistics, the meaning should be obvious. If you don't, the best way to put it is that the value of one of the variables doesn't depend on the value of the other one in any systematic way. Knowing that one of them is 3 doesn't let you make any guess at all about what the other one might be. Read More

Suppose you conduct an experiment that yields a collection of pairs, (x1, y1), (x2, y2), (x3, y3), ... (xn, yn). In other words, yi is the value of variable y when variable x assumes the value xi. Let us call the average of the xi values x-bar and the average of the yi values y-bar. Then an x-deviation is xi - x-bar and a y-deviation is yi - y-bar. One product of a pair of… Read More

According to the American CIA, worldwide the number of boys born to the number of girls is 1.07:1, which implies a probability of about 0.517. This varies somewhat by country, for instance. At one extreme, according to the list of countries by sex ratio presented in wikipedia is Liechtenstein at 0.558, at the other Haiti at 0.503. Read More

Each toss has a 1/2 probability of getting heads. Each toss is an independent event. So three heads in a row (heads AND heads AND heads) would have a probability of: 1/2 * 1/2 * 1/2 = (1/2)^3 = 1/(2^3) = 1/8 = 12.5% Read More

The middle value in an ordered set is the median. Example: In the set - 1, 3, 4, 11, 15, 17, 19 11 would be the median. Read More

Yes. In applying inferential statistical methods the assumption is made that at least some of the variation observed in the data is due to randomness and that the laws of probability can be applied to take this into account in drawing conclusions from the data. Read More

Managers use statistics to try and predict future events, look at how the business is doing and make decisions based on the statistics. For example: Let's say you owned a resteraunt and had it open 7 days a week. If statistics show that Wednesdays aren't really a good day for customers, then you can reduce the hours which you are open and save money in the process. Read More

The probability of rolling two 6-sided dice and getting the same number on each is 1/32, or "one out of thirty two". This is because there are 6 oppurtunities on each dice, and the probability of getting the same of the 6 oppurtunites on two dice is 6 squared, which is 32. Read More

The sample space of an experiment would be the set of all possible outcomes. If you are reaching your hand into a bag and pulling out a marble at random, the outcomes will either be (red)(red)(yellow)(yellow)(yellow)(yellow)(yellow). This gives seven different options. This will obviously change each time a marble is removed or added. Read More
