Good afternoon,
What is the guidance for psychometric sample size requirements?
For instance, say I developed a psychometric tool to assess resilience with scores ranging from 0 to 100.
Let’s say, the Los Angeles County Unified School District has agreed to use my tool to assess resilience for High School students.
Before the tool is used to establish a resilience baseline, I want to know how many subjects I need to ensure they are representative of 100,000 High School students in the district.
Please advice.
Regards, Al
