It's a statistical tool used in psychology. A simple way of calculating the measure of dispersion is to calculate the range. The range is the difference between the smallest and largest value in a set of scores. This is a fairly crude measure of dispersion as any one high or low scale can distort the data. A more sophisticated measure of dispersion is the standard deviation which tells you how much on average scores differ from the mean.

4 The formula is sum of scores divided by number of scores.

The probability is 0.68

If you are able to determine the IQ of a cross section of people (through an IQ test) who have taken the MAT, you can develop a cross relation between MAT scores and IQ. Assuming that the relationship is almost linear (or an invert - if you consider people like me, who don't do well in tests!) you can predict the IQ of people on the basis of their MAT scores. Though the results may not be as accurate as a discrete IQ test, the indicators should be sufficient to determine probable IQ. Hope this helps

There is no statically significant difference between the average IQ scores of men and woman

There is very little difference between men's and women's golf scores, they both shoot considerable scores under par. The difference is that the women play holes from tee boxes that are a lot farther forward than the men, this isn't because they aren't as good, but it is because they do not hit the ball as far. The handicap systems are the same, for amateur golfers are the same for men and women, but as you know professional golfers don't have handicaps.

Not necessarily. The difference may be genuine and that is not the "fault" of the assessment.

There is a subtle difference between debt settlement and bankruptcy. Debt settlement allows a person to pay off some of their debt with their creditors. Bankruptcy claims do not result in payment of the debt. Either practice creates bad credit scores for the consumer.

About 95% of the population has IQ scores between 70 and 130. This is the average range on a standard IQ test.

Given any two groups there will usually be random variations in their scores. A proper statistical test is designed to assess whether the observed difference is likely to be a result of such random variation or if it due to a genuine - reliable - difference between the groups.

the attaker location is not in the goal keeper zone ,but the striker always in the front and he tries to not be offside that why the striker scores a lot of goals more than the attaker.

Norm-referenced test is an estimate of the position of the tested individual. A criterion-referenced test is one that provides for translating test scores.

mean and median scores. mean is an average of all the scores added together divided by the number of entries. median is the number found in the middle, when catogorized from least or greatest or vice versa. it doesnt matter which way its sorted. the middle number's still the same.
