I want to measure IQ of college students for a research project I am working on.
After searching for valid IQ test for research that is also low cost/free, I came across this site-https://openpsychometrics.org/
They have an IQ test listed as,The Full scale IQ test (https://openpsychometrics.org/tests/FSIQ/)
They also have listed some research papers that they claim have used their data (https://openpsychometrics.org/_rawdata/cited/) but I simply used my browser search option to search for the terms "IQ" and "Intelligence" in that page, with O results.
Is the full scale IQ test valid and useable for publishable academic research work? Shall I administer their test on a sample from my target population and use it for my research work? If not, what are some other free or low cost options avaible for me?
