Pagkuhan ng Sample Size

Pagkuhan ng Total Population Size

• Hakbang 1: I-add ang lahat ng bilang ng populasyon:
  • 435 + 327 + 295 + 312 + 457
• Kabuuan: 1826
• Big N (Total Population Size): 1826

Pagkuhan ng Total Sample Size gamit ang Lovense Formula

• Lovense Formula: ( n = \frac{N}{1 + N \cdot e^2} )
• Big N: 1826
• Margin of Error (e): Walang binigay, kaya gagamitin ang 5%
  • Convert sa decimal: 0.05
• Substitute ang values:
  • ( n = \frac{1826}{1 + 1826 \cdot (0.05)^2} )
• Simplify:
  • ( 0.05^2 = 0.0025 )
  • ( 1826 \times 0.0025 = 4.565 )
  • ( 1 + 4.565 = 5.565 )
  • ( n = \frac{1826}{5.565} \approx 328.1 )
• Total Sample Size (Buong Numero): 328

Pagkuhan ng Sample Size para sa Bawat Respondents

HE (Population Size: 435)

• Formula: ( \frac{435}{1826} \times 328 )
• Sample Size: 78.1, i-round off to 78

• Formula: ( \frac{327}{1826} \times 328 )
• Sample Size: 58.7, i-round off to 59

STEM (Population Size: 295)

• Formula: ( \frac{295}{1826} \times 328 )
• Sample Size: 52.9, i-round off to 53

ABM (Population Size: 312)

• Formula: ( \frac{312}{1826} \times 328 )
• Sample Size: 56.0, buo na 56

YUMES (Population Size: 457)

• Formula: ( \frac{457}{1826} \times 328 )
• Sample Size: 82.0, buo na 82

Pag-verify ng Total Sample Size

• Pag-add ng Sample Size:
  • 78 + 59 + 53 + 56 + 82 = 328
• Kumpirmadong Total Sample Size: 328
