आधुनिक संचार और सामाजिक विज्ञान अनुसंधान में, अनुसंधान की गुणवत्ता और विश्वसनीयता इस बात पर निर्भर करती है कि डेटा किस प्रकार एकत्र किया गया है और किस प्रकार के नमूने (Sample) का चयन किया गया है। किसी बड़े जनसंख्या समूह के पूरे डेटा को इकट्ठा करना अक्सर असंभव और महंगा होता है, इसलिए शोधकर्ता नमूने का चयन करके जनसंख्या के व्यवहार, विचारों और रुझानों का अनुमान लगाते हैं। इसलिए, अनुसंधान में नमूना लेना अत्यंत महत्वपूर्ण है क्योंकि यह अनुसंधान के निष्कर्षों की सटीकता और सामान्यीकरण (Generalization) की क्षमता को प्रभावित करता है। यदि नमूना सही तरीके से नहीं चुना गया, तो परिणाम पक्षपाती (Biased) हो सकते हैं और पूरे जनसंख्या पर लागू नहीं किए जा सकते। नमूना लेने के कई तरीके हैं, जिन्हें मुख्य रूप से दो श्रेणियों में बाँटा जा सकता है: संभावना आधारित नमूना (Probability Sampling) और गैर-संभाव्यता आधारित नमूना (Non-Probability Sampling)। संभावना आधारित नमूने में प्रत्येक व्यक्ति के चयन की संभावना ज्ञात और समान होती है, जबकि गैर-संभाव्यता आधारित नमूनों में चयन का आधार शोधकर्ता का विवेक या सुविधा होता है। पहली प्रमुख संभावना आधारित
