Small R Square Value

Post by spiking »

I have all other R Square values above 0.6 except for one item which has a small R Square value of 0.05.

Is there any journal papers published that can help explain and justify the acceptance of a small R Square value?

Please advise.

Thank you.

Problem solved.

I used G*Power to calculate the total sample size required based on the statistical power that I need.
