मानवविज्ञान में अनुसंधान के दौरान एकत्र किए गए आंकड़ों का केवल संग्रह और प्रस्तुतीकरण पर्याप्त नहीं होता, बल्कि उनके बीच विद्यमान संबंधों, प्रवृत्तियों तथा कारणात्मक संभावनाओं को समझने के लिए सांख्यिकीय विश्लेषण आवश्यक होता है। सहसंबंध (Correlation) तथा प्रतिगमन (Regression) दो महत्वपूर्ण सांख्यिकीय विधियाँ हैं, जिनका उपयोग मानवविज्ञान में जैविक, सामाजिक, सांस्कृतिक तथा जनसांख्यिकीय आंकड़ों के विश्लेषण में व्यापक रूप से किया जाता है। दोनों विधियाँ चरों के बीच संबंधों का अध्ययन करती हैं, लेकिन उनके उद्देश्य और व्याख्या की प्रकृति अलग-अलग होती है। सहसंबंध का अर्थ दो या दो से अधिक चरों के बीच संबंध की दिशा और मात्रा को मापना है। यदि एक चर में परिवर्तन के साथ दूसरे चर में भी नियमित परिवर्तन होता है, तो दोनों के बीच सहसंबंध माना जाता है। उदाहरण के लिए, किसी जनसंख्या में ऊंचाई और वजन के बीच सामान्यतः धनात्मक सहसंबंध पाया जा सकता है। इसी प्रकार आयु और कुछ शारीरिक मापों, शिक्षा और आय, परिवार के आकार और सामाजिक-आर्थिक स्थिति आदि के बीच संबंध का अध्ययन किया जा सकता है। सहसंबंध गुणांक सामान्यतः -1 से +1 के बीच होता है। +1 पूर्ण धनात्मक सहसंबंध, -1 पूर्ण ऋणात्मक सहसंबंध और 0 का अर्थ है कि रैखिक सहसंबंध नहीं है। मानवविज्ञान में सहसंबंध की उपयोगिता अनेक स्तरों पर दिखाई देती है। शारीरिक मानवविज्ञान में शरीर की ऊंचाई, वजन, सिर की लंबाई, सिर की चौड़ाई, शरीर के विभिन्न अनुपातों तथा अन्य मानवमितीय मापों के बीच संबंधों का अध्ययन किया जा सकता है। इससे यह समझने में सहायता
