जनसंख्या माध्य और मानक विचलन दो सामान्य मानदंड हैं। सांख्यिकी में, ग्रीक प्रतीक आमतौर पर जनसंख्या मापदंडों को दर्शाते हैं, जैसे कि माध्य के लिए μ (meu) और मानक विचलन के लिए σ (सिग्मा)।
Important Points
\(̅{X}\) = प्रतिदर्श माध्य सूत्र निम्नलिखित है:
\(̅{X}\) = ( Σ xi ) / n
जनसंख्या मानक विचलन = मानक विचलन आंकड़ों के वितरण के प्रसार को मापता है। यह प्रत्येक आंकड़े के बिंदु और माध्य के बीच की विशिष्ट दूरी को मापता है।
σ =√([Σ(x - u)2]/N)]
S = प्रतिदर्श मानक विचलन = σ =√([Σ(x - x̅ )2]/(n - 1)]
