Select every statement that is TRUE about measuring intelligence.
Hints
- Only one option is false; find the Flynn-effect direction error.
- The Flynn effect is a RISE, not a decline.
Show the answer
- A. Deviation IQ compares people to same-age peers.
- B. Deviation IQ has a mean of 100 and an SD of 15.
- D. Genes change too slowly to explain the Flynn effect.
- E. Roughly two-thirds of the population falls between 85 and 115.
Why
The mean-100/SD-15 scale, the 68% within one SD, the too-slow genes point, and peer comparison are all true. The Flynn effect is a RISE in scores, not a decline - the one false option.
