| Aug 21, 2013 at 21:13 | comment | added | amiangshu | I appreciate your help. I have so far randomly analyzed 200 threads and found that none of those had discussions about security. According to Yamane's simplified formula, if I take ±5% precision and 95% confidence interval, I need 400 samples. Do you think that if none of the 400 randomly selected threads were relevant to security will justify the effectiveness of my keywords? | |
