अंक = [14, 26, 44, 61, 84]
छात्रों की संख्या = [91, 78, 95, 36, 98]
प्रयुक्त सूत्र:
माध्य = (Σ(अंक x आवृत्ति)) / (Σ(आवृत्ति))
गणनाएँ:
Σ(अंक x आवृत्ति) की गणना करें
14 x 91 = 1274
26 x 78 = 2028
44 x 95 = 4180
61 x 36 = 2196
84 x 98 = 8232
⇒ Σ(अंक x आवृत्ति) = 1274 + 2028 + 4180 + 2196 + 8232 = 17910
Σ(आवृत्ति) की गणना करें
91 + 78 + 95 + 36 + 98 = 398
माध्य = Σ(अंक x आवृत्ति) / Σ(आवृत्ति)
⇒ माध्य = 17910 / 398
⇒ माध्य = 45
इसलिए, सही उत्तर विकल्प (1) है।
