A/B Test کا حساب کیسے لگائیں

A/B Test کیا ہے؟

A/B testing (split testing) compares two versions of a web page, email, or other element to determine which performs better. Statistical significance testing ensures the observed difference is not due to random chance. A result at 95% confidence means there is only a 5% probability the difference occurred by chance.

مرحلہ وار گائیڈ

1Calculate conversion rates for each variant: rate = conversions / visitors
2Compute the pooled proportion: p_pool = (cA + cB) / (vA + vB)
3Calculate the standard error: SE = sqrt(p_pool × (1 − p_pool) × (1/nA + 1/nB))
4Z-score: z = (rateB − rateA) / SE
5If |z| ≥ 1.96, the result is significant at 95% confidence (two-tailed)
