correlation between two sets of IQ scores

*****

Objective:

Write a one-page paper on the correlation ***** two ***** of ***** scores.

Methodology:

Consult relevant information sources that discuss the correlation between two sets ***** IQ scores.

Conclusion:

Data used for determining multiple ***** scores can be deceiving and may not be statistically valid in all cases.

To *****gin, ***** IQ score is a statistically derived number ***** indicates relative and comparative abilities that ***** be ***** to learn and gain knowledge. It's important ***** understand ***** this is an independent indicator of probable potential.

When the correlation ***** the two sets of *****s is.80, we can ***** referring to the ***** between the person's IQ and ***** predicted level of achievement. It can also be reflective of norming, which means that once a high-r*****nge test has been created from prior scores on other tests, then you calculate the testing results for more than one set of scores. Testees ***** ***** obtain the raw score or the correlated mean from the results of two tests. However this has nor ***** proven ***** be an accurate measure, i.e. by factor ********** on a v*****riety of high range tests. So this type of reliability scoring is flawed mathematically.

There*****e if we take two *****s that are ***** with each *****, both of ***** have reliabilities in the.80s, the corrected correlation after assuming the reliabilities ***** 1.25 which is likely to be at least somewh***** suspect. This is considered imperfect data and the ***** can be restricted by problems in distributions of grades and by narrow ranges in abilities of participants.

The scale most used for IQ ***** is using a *****t*****l population of 100 and a st*****ndard deviation of 16. Any prior scores to be ***** have ***** be converted to th***** *****, if *****ey are not already expressed as such. Therefore, data used for determining multiple IQ scores can be deceiving and ***** not be statistically valid in all
