Answer:

In a cross-sectional study that compares IQ scores, the difference in IQ scores of 25-year-olds and 45-year-olds is due to differences in educational attainment.

Explanation:

In cross sectional research the subjects will be tested more than once on different time in order to measure whether there is a change in those time period.

When studying IQ, this type of research could skew the data because IQ can be influenced by the things that we read/we learn. So if there is a change in IQ, the change might not be caused by natural occurence.
