Sentence examples for variance in intelligence from inspiring English sources

Other findings included a wider variance in intelligence among boys than girls, and descriptions of the predictive value of IQ in estimating future education, examinations and health.

Fourth, a meta-regression of year of assumed study performance on within-study variances were calculated to account for the possibility of decreasing population variance in intelligence as cause for intelligence test gains.

As we found no difference across ethnicities in residual variance in intelligence once deletion length was controlled, it remains possible that total absolute variance in FSIQ associated with non-genetic factors does not differ across groups.

The DNMT3L genotype accounted for around 0.5% of the variance in intelligence, with the common homozygote (DNMT3L 11330CC) being associated with an approximately 2 point reduction in standardised intelligence.

In this study the DNMT3L genotype accounted for around 0.5% of the variance in intelligence, with the common DNMT3L homozygote genotype being associated with an approximately 2 point reduction in standardised intelligence.

The specific environmental mechanisms responsible for a portion of the variance in intelligence, however, are unclear.

Second, our finding that genetic dominance explains part of the variance in adult intelligence is interesting in the context of the well-known increase in heritability of intelligence over age.

An additional analysis showed that the variance in fluid intelligence that was attributable to processing speed was not fully shared with the variance attributable to frontal function.

Hierarchical regression analyses showed that the processing speed and frontal function measures accounted for significant variance in fluid intelligence performance, but there was also a residual effect of age after controlling for each variable individually as well as both variables.

Moreover, gene finding studies may benefit from genetic resemblance between spouses since genetic variants that are shared between spouses more often than expected by chance, are possibly the same variants that account for part of the variance in general intelligence.

Many psychologists now believe there is clear evidence that heredity is important but not all powerful, and that genes account for about 50percentt or more of the variance in I.Q., or intelligence quotient.
