Generally, boys tend to have a slightly higher average IQ than girls.
According to research, the mean IQ of males is 4 to 6 points higher than that of females. It's also important to note that males exhibit a higher variability in IQ scores. This means you'll find more males at both the very high and very low ends of the IQ spectrum. The male advantage also appears more pronounced among Hispanics compared to Caucasians and blacks.
Here's a summary:
| Gender | Average IQ | Variability |
|---|---|---|
| Males | 4-6 points higher (on average) | Higher |
| Females | Lower (on average) | Lower |
This difference in variability also leads to a higher male-to-female ratio in the gifted range.
