Calculation of Arithmetic Mean (Average Age):

Age Class IntervalMid-Value (x)Frequency / Women (f)f × x
15 - 2017.58140.0
20 - 2522.510225.0
25 - 3027.58220.0
30 - 3532.56195.0
35 - 4037.54150.0
40 - 4542.57297.5
45 - 5047.53142.5
50 - 5552.52105.0
55 - 6057.52115.0
60 - 6562.500.0
Total-∑f (N) = 50∑fx = 1590.0
  1. Direct Method Formula:
    Mean (X̄) = ∑fx / N
  2. Substitution:
    X̄ = 1590 / 50 = 31.8 years

Final Answer: The average age of the women is 31.8 years.

हिंदी में प्रश्न एवं आदर्श उत्तर

आत्महत्या करने वाली 50 महिलाओं की आयु नीचे दी गई है । इससे महिला की औसत आयु ज्ञात कीजिए ।
वर्ष में महिला की आयु : 15-20, 20-25, 25-30, 30-35, 35-40, 40-45, 45-50, 50-55, 55-60, 60-65
महिला की संख्या : 8, 10, 8, 6, 4, 7, 3, 2, 2, 0
N = 50

सांख्यिकीय औसत आयु (समांतर माध्य) की गणना:

आयु वर्ग (वर्ष)मध्यमान (x)महिलाओं की संख्या (f)f × x
15 - 2017.58140.0
20 - 2522.510225.0
25 - 3027.58220.0
30 - 3532.56195.0
35 - 4037.54150.0
40 - 4542.57297.5
45 - 5047.53142.5
50 - 5552.52105.0
55 - 6057.52115.0
60 - 6562.500.0
योग-∑f (N) = 50∑fx = 1590.0
  1. माध्य का सूत्र:
    समांतर माध्य (X̄) = ∑fx / N
  2. मान रखने पर:
    X̄ = 1590 / 50 = 159 / 5 = 31.8 वर्ष

उत्तर: आत्महत्या करने वाली महिलाओं की औसत आयु 31.8 वर्ष है।
