Dear Rana

My advice to use G*Power software.

G*Power software is an effective tool to calculate sample size for many ranges of experiments. Also, you can determine effect size and power of the test, G*Power is free to download and easy to use after reading the manual, the download link:

The link to download G*Power manual:

Use test family key, then choose Z tests, and from statistical test key select ( correlations: Two independent Pearson rs ( Two samples ) ).

I hope that be useful for you.

Good Luck
