Why would an IQ test be developed so most people would score between 85 and 115?
An IQ test is simply a (somewhat flawed) means of assessing a person's "relative intelligence". It is important that IQ is not extremely important when working with such a measure in psychology. Now, the IQ test is designed such that scores follow a pattern known as a "normal distribution". This is not simply an expected distribution! This distribution is very important in the study of statistics, and has many applications to scientific disciplines (such as psychology). A standard deviation is essentially a measure of distance from the mean. For example, say that the average person lives to be 75, with a standard deviation of 4. This means that a person who lives to be 79 would be one standard deviation above the mean, and a person who lives to be 67 would be two standard deviations below the mean. As a table depicting the normal distribution can show, one standard deviation above the mean is at the 84th percentile, while one standard deviation below the mean is at the 16th percentile (two stds above: 97.5th, two stds below: 2.5th) This means that an IQ score of 115 is at the 84th percentile, while an IQ score of 85 is at the 16th percentile. 68% of all people are within this range, and that is "most" people.
What it is the difference between statistic and statistics?
Statistic is singular; statistics is plural. Statistic is a single data point. Statistics is the study of collections of related data points.
What is the term associated with the variable that is manipulated in the study?
That's the independent variable.
What number of observations would be required in a time study in order to obtain a 95 percent confidence that the average time observed was no more than 0.6 minutes from the true mean?
What number of observations would be required in a time study in order to obtain a 95 percent confidence that the average time observed was no more than 0.6 minutes from the true mean, assuming a standard deviation of cycle time of 1.8 minutes?
Why do you need study of statistic?
Statistics is the collection , tabulation , analyse and interpretation of data.Data is needed in every section .
What is an acceptable standard deviation?
An acceptable standard deviation depends entirely on the study and person asking for the study. The smaller the standard deviation, the more acceptable it will be because the less likely there are to be errors.
How do you reverse an average?
You cannot. The average is the mean of a number of observation, and each individual observation cannot be uncovered. We therefore also often study "Variation" or "Standard Deviation" being the sum of square of each observation and the average. You get the Standard deviation by tracting the square root of the variance. Thsi indicates the "spread" of the values.
What is the study of mathematical probability distribution deviation?
It is "probability".

An experiment involves selecting a random sample of 256 middle managers for study One item of interest is annual income The sample mean is computed to be 35420 and the sample standard deviation is 205?
The deviation would be how much off it would be off. Since this is a sample, it is impossible to get completely accurate results.
