सार

चर मापने योग्य विशेषताएँ हैं; परिकल्पनाएँ चरों के बीच संबंधों के बारे में परीक्षण-योग्य पूर्वानुमान हैं।

मुख्य बिंदु

  • स्वतंत्र चर में हेरफेर किया जाता है या उसे कारण माना जाता है; आश्रित चर मापा गया परिणाम है।
  • बाह्य चर परिणामों को प्रभावित कर सकते हैं और उन्हें नियंत्रित करना चाहिए।
  • मध्यवर्ती चर संबंध को समझाते हैं; मध्यस्थ (moderator) चर उसकी शक्ति बदलते हैं।
  • शून्य परिकल्पना (H₀) कहती है कि कोई अंतर या संबंध नहीं है; वैकल्पिक (H₁) कहती है कि है।
  • दिशात्मक परिकल्पनाएँ दिशा का पूर्वानुमान करती हैं; अदिशात्मक नहीं।
  • अच्छी परिकल्पना परीक्षण-योग्य और स्पष्ट रूप से कही गई होती है।

व्याख्या

  • परिकल्पनाओं का परीक्षण होता है, उन्हें सिद्ध नहीं किया जाता।
  • H₀ अस्वीकार करना H₁ का समर्थन करता है।
  • संक्रियात्मक परिभाषाएँ चरों को मापने योग्य बनाती हैं।
  • गुणात्मक अध्ययनों में परिकल्पनाओं के बजाय मार्गदर्शक प्रश्न हो सकते हैं।
  • भ्रमित करने वाले (confounding) चर निष्कर्षों के लिए ख़तरा हैं।

चरण-दर-चरण

  1. पूछी गई अवधारणा, विधि या नीति पहचानें।
  2. परिभाषा, विचारक, वर्ष या नियम याद करें।
  3. उसे स्थिति पर लागू करें और अतिवादी विकल्प हटाएँ।

उदाहरण

  • "शिक्षण विधि अंकों को प्रभावित करती है": विधि = स्वतंत्र, अंक = आश्रित।
  • H₀: "दोनों विधियों के बीच पठन अंकों में कोई अंतर नहीं है।"
  • "लड़कियाँ लड़कों से अधिक अंक लाएँगी" → दिशात्मक परिकल्पना।

ग़लतियों से बचें और उन्नत बिंदु

  • सामान्य भूल: स्वतंत्र और आश्रित को उलट देना।
  • सामान्य भूल: यह कहना कि परिकल्पनाएँ सिद्ध होती हैं।
  • सामान्य भूल: बाह्य चरों की अनदेखी।

त्वरित पुनरावृत्ति

  • स्वतंत्र → आश्रित।
  • H₀ बनाम H₁।
  • दिशात्मक बनाम अदिशात्मक।
