In other words there appears to be a connection between full moons and birth rates. However many studies have shown that any perceived correlation is due in fact to chance. There is no evidence to support the theory that the phases of the moon affect human behavior in any way. So even when there is a positive correlation it does not necessarily mean there is a cause and effect relationship between the two elements in the correlation study. For the second question if a study showed that Americans with the top 5 of IQ scores made an average of 22 000 a year while those in the middle 5 made an average of 40 000 you would say there is a negative correlation between IQ and income levels. To describe the results of the study you could say that there is no evidence that IQ determines income level. In other words you do not need to have a high IQ to make a lot of money. This conclusion is obvious. But let s look at how these same correlation study results can be used to come up with a ridiculous conclusion. The second example shows that there is no connection between a high IQ and a high income level. Is that the same as saying that the dumber you are the more money you will make Of course it isn t. This type of conclusion shows one of the dangers of correlation studies. Even if the study uses accurate data the way in which it is interpreted can be wrong and even foolish. When you encounter a correlation study as with survey and poll results do not assume the numbers and conclusion are correct. Ask questions and look at supporting data. Does the study make sense Or does it seem too convenient for the advertiser politician new reporter .
