I am using the IPIP Neo-120 and want to calculate how much personality diversity exists in the team. Is there a way I can calculate diversity and make a percentage to assign it meaning i.e. whether it is too high or low? This inventory uses a 5-point Likert scale.
I know standard deviation is one way to look at personality diversity but how can I convert it into a standard percentage where we can even compare teams? I don't think I can make a percentage by dividing the SD with the maximum possible SD for a 5-point scale (2.83 I think?) to kind of give it meaning whether it is too high or low. Another idea I had was to consider the SDs for each item and turn them into z-scores and then percentiles.
I feel a bit lost on how to tackle this and would appreciate any help, thank you!
You may try the following approach
If you have five types of personality (e.g., Big-Five personality): A, B, C, D, E
Step 1: calculate the standard deviation of A, B, C, D, E among team members for each team, and the calculate the average score
Step 2: For A, B, C, D, E, calculate the mean for each team, and then calculate the absolute difference between the mean scores of A, B, C, D, E (10 possible comparisons), and dividing the absolute difference score by the possible, maximum absolute difference between the mean scores of A, B, C, D, E
Step 3: Multiply Step 1 score and Step 2 score
