Jelaskan Test scores dari Sebaran normal dalam bahasa sunda

The IQ score of an individual for example can be seen as the result of many small additive influences: many genes and many environmental factors all play a role.

IQ scores and other ability scores are approximately normally distributed. For most IQ tests, the méan is 100 and the standard deviation is 15.

Criticisms: test scores are discrete variable associated with the number of correct/incorrect answers, and as such they are related to the binomial. Moreover (see this USENET post), raw IQ test scores are customarily 'massaged' to force the distribution of IQ scores to be normal. Finally, there is no widely accepted model of intelligence, and the link to IQ scores let alone a relationship between influences on intelligence and additive variations of IQ, is subject to debate.
