This visualisation shows the distribution of scores from an experimental cognitive assessment I have been building as a side project.

The test is loosely based on a multi-domain structure (reasoning, working memory, spatial ability, processing speed and verbal ability). The current dataset includes responses collected from Reddit, LinkedIn, and personal networks.

Sample size: 98 participants

Notes:

• This is not a standardised or clinical IQ test
• Scores are based on a provisional calibration and should be interpreted as estimates
• The dataset is still growing and subject to sampling bias

Self-collected data from https://chccognitivetest.vercel.app

Hi everyone! This is a repost, if you want to see the original post you may go to this link: https://www.reddit.com/r/iqtest/comments/1spllm0/i_have_created_a_cognitive_assessment_based_on/

For context, I have created a this cognitive assessment I have built that aims to test on all aspects that measures IQ and created the assessment as I believe everyone should deserve a good and accessible IQ assessment.

Link to the assessment: https://chccognitivetest.vercel.app/

What you are seeing above is a distribution of the scores for each range based on everyone who has taken the assessment and opted to share their data (hence the repost) with my sources not only coming from Reddit, but also through my LinkedIn, Instagram and word of mouth. The nine categories are:

1. Moderate Intellectual Disability (40-54)
2. Mild intellectual Disability (55-69)
3. Borderline (70-79)
4. Low Average (80-89)
5. Average (90-109)
6. High Average (110-119)
7. Superior Intelligence (120-129)
8. Very Superior Intelligence (130-139)
9. Gifted (140+)

I did not include a any scores below 40 and above 160 as my experimental assessment aims to measure the range of 40-160. And also disclaimer this are data that was pre-normed and regardless of whether its normed this assessment should be taken with a grain of salt, not meant to be used as an official medical instrument :')

Currently, I am still in the process of norming the assessment based on the data and I have 79 responses thus far. I would appreciate if more people can try out this assessment as my norming or the website in general is still a work in progress. For those who tried out, I thank you all for your time and feel free to try out the assessment again! As I have made some considerable restructuring and calibration so the assessment wont feel "as same" as when you first took it :)

Lastly, there is also a survey after the test so feel free to do it so I can continue to improve on the test as currently I am basing the difficulty on theoretical numbers and I would love to use a data-driven approach in calibrating the difficulty of the test. If you do not wish to do the survey, fret not, no data will be disclosed to me as I have to comply to PDPA. For those who did the survey, thanks for you support! Your data will only be used by me and only me for improving the test. Have fun everyone!
