Question

Sir francis galton assumed that skull size is related to intelligence, this was _____ measure of intelligence.

Answer 1

Answer;

A reliable, but not valid

Sir francis galton assumed that skull size is related to intelligence, this was a reliable but not a valid measure of intelligence.

Explanation;

-Intelligence reflects the ability to learn from experience, to acquire knowledge, to use resources effectively in adapting to new situations or solving problems, cannot me be measured directly.

-Test reliability and validity are highly desirable for an accurate assessment of intelligence. Also knowing that a test is reliable guarantees that it is also valid.

-It is possible to have reliability but lack validity at the same time, for instance; Sir Francis Galton assumed that skull size is related to intelligence, and he was able to measure skull size with great reliability. However, the measure of skull size was not valid simply because it had nothing to do with intelligence. In this case, then, we have reliability without validity

Answer 2

The answer that best fits the blank is "RELIABLE, BUT NOT A VALID". Sir Francis Galton is a known anthropologist and eugenicist, and for him, skull size in relation to intelligence might be reliable, but this do not have any evidence to be considered valid.
