Hey guy - I love these - have filed the links so that I can include them in notes to clients about use of tools, even something as simple as the Kilmann conflict resolution instrument as it still has value for setting expectations.
Hello Perim Group, I very much appreciate the comment and for helping to spread the word about the importance of test validity. Yes, there are many useful assessments out there but there are also many that we need to be careful about before using.
Thanks LailyDife and thanks for reminding me to continue with these videos. Look for another coming soon. Also, to help me prioritize, I'd love to hear the kinds of topics you'd like to hear more about.
If you could possibly go over selection decisions or training & development and the processes that take place that would be helpful. Also again you explained everything perfectly and it helped a lot with my exam. Thank you :)
Sorry the late response LailyDife (somehow I missed this note). Got it. More on employee selection decisions as well as T&D topics will be posted soon.
I did not mind your voice in the previously mentioned video - Great job covering these topics - Did the person who made those critical comments give you links to her perfectly recorded lecture videos?
Thanks for this thoughtful note Brandon. No one actually criticized my voice. As an introvert, I just tend to be highly self-conscious when I know I'm being recorded. I figure after my 100th video, I'll learn to relax. :)
Excellent informative presentation. Question/s ... How can I determine validity on intelligence/ability test, in particular construct validity as this subject matter cannot possibly be covered comprehensively or can it?
Good question Locarla. In order to establish construct validity of an intelligence test (or any other test), you would first need to define what you mean by "intelligence." This is in fact one of the most challenging phases of test design and validation - i.e., defining what it is you are trying to measure. Intelligence is especially tricky because there are different schools of thought on what intelligence (as a concept) is. For example, Spearman proposed that intelligence is made of just one big factor called "general intelligence," Cattell proposed a 2-factor (fluid and crystalized) model, Sternberg proposed a 3-factor model, and Gardner, 8-types. Once you've clearly defined the concept, then (a) you can select an established (i.e., valid and reliable) test that measures the same or similar concept, (b) administer both the new test and established test to a sample of test-takers, then (c) correlate the scores of the two tests. We're looking for a relatively high correlation between the two tests (e.g., 0.4+). Hope that helps and thanks for that question!
Thank you so much! your videos are very useful ... I'm studying for my exam and I have some questions, is there any email address that I could contact?
Just about any tool (e.g., MS Excel, SPSS, SAS, R, etc.) that can generate correlations can be used to validate a test. I'll see if I can include a tutorial on this in the future.
Thank you! You just explained simply what a whole book couldn't.
Thank you so much for your kind words!
wuoooooooo! to be honest, it has been the best explanation ever!!!!!!!!!
Please keep doing these type of videos; they're great!
Thank you jose!
Please do send topic suggestions to "jeongs2099@gmail.com"!
Thank you- I'm studying for my EPPP and this is really helpful!
Excellent presentation. 5 Stars
Please, we need more :)
Thank you kindly zendar2007! Please do send topic suggestions to "jeongs2099@gmail.com"!
Thank you so much for these videos and making them short enough for my brain to process!
This is really helpful....am studying for psychometrics exam

Great explanation and excelent videoquality!
very informative. Helped me much to understand this concept quickly. Thanks.
This saved my life
This is great, I understood everything!!! Please do more videos!!! On I/O!!

Hope that helps and thanks for that question!
Succinctly explained.. thankyou.
thank you sir
I intend to do an educational video. can you please tell me what the steps and the materials you used to make this video? thank you.
Thank you so much! your videos are very useful ... I'm studying for my exam and I have some questions, is there any email address that I could contact?
Hi thanks a lot for the video! Could you briefly introduce any tools to test validity, such as SPSS?
Just about any tool (e.g., MS Excel, SPSS, SAS, R, etc.) that can generate correlations can be used to validate a test.
I'll see if I can include a tutorial on this in the future.
Now that I have Camtasia, I'll be posting some SPSS, PSPP, and R tutorials.
