Data on smoking was self-reported by the twins ...

Deviation IQ Scores are a standard score with a mean of 100 and a standard deviation of 15. Z-scores can be transformed into Deviations IQ scores by multiplying the given Z-score by 15 (the standard deviation of the distribution of Deviation IQ scores), and adding 100 (the mean of the distribution of Deviation IQ scores) to this product.

Once you add one to your n value, multiply this sum by 100.

The percentile of a score is the percentage of people who score equal to or below the score. For example, an IQ score of 70 is in the 2nd percentile (for SD = 15), which means that only 2% of people score 70 or lower. IQ 125 is at the 95th percentile - 95% of people have an IQ equal to or less than 125.Learn the how to distribute a press release, including press release distribution tips for every step of the process.

The studies with a control group ( n = 23) reported a FSIQ mean between 100.0 (17.0 SD) and 117.1 (16.4 SD) for full-term children.

"IQs are always calculated relative to a person's age, whether that age is 10, 15, 25, 50, 72, or 88.
