हे साधन इंग्रजीसाठी (आणि काही संबंधित भाषांसाठी) कॅलिब्रेट केले आहे. मराठी मधील निकाल अर्थपूर्ण नसण्याची शक्यता आहे.

कधी वापरायचे

Use SMOG whenever you are writing for health and medical audiences. The National Institutes of Health, the CDC, and most patient-education guidelines recommend SMOG specifically because it correlates with 100% comprehension rather than approximate understanding — critical when readers must follow instructions exactly.

तुलना

SMOG is the strictest of the polysyllable-based formulas; expect SMOG to land 1–2 grade levels above Flesch–Kincaid on the same text. Compared to Dale–Chall, SMOG ignores familiarity (treats "everyone" and "epistemology" similarly) but is far simpler to compute.

हे कसे कार्य करते

SMOG (Simple Measure of Gobbledygook) was created by G. Harry McLaughlin in 1969 and is the most widely used readability formula for health communication.

The score is the years of education needed to comprehend the text. SMOG 7 means a typical 7th grader should understand it.

Unlike Flesch-Kincaid, SMOG is calibrated for 100% comprehension rather than approximate understanding.

वारंवार विचारले जाणारे प्रश्न

Why is SMOG popular in healthcare?

SMOG correlates strongly with comprehension among adults reading medical material. It is the recommended formula by the National Institutes of Health (NIH) for evaluating patient education materials.

Does SMOG need a 30-sentence sample?

The original formula expects exactly 30 sentences. This tool scales the polysyllable count proportionally when your text is longer or shorter.

What is a healthy SMOG score?

For consumer health communication, aim for SMOG 6–8.

व्यावहारिक उदाहरण

इनपुट

Patients experiencing persistent symptoms should consult their physician immediately for evaluation.

आउटपुट

SMOG Index: 14.2 — College level.

Five polysyllabic words ("experiencing", "persistent", "symptoms", "physician", "immediately", "evaluation") drive the SMOG estimate. SMOG uses √polysyllables, so a few extra long words have a noticeable but bounded effect.

सामान्य चुका

  • Designed for samples of 30 sentences; very short text gives unstable scores.
  • English-calibrated; do not use for translated material without re-validation.
  • Counts every 3+ syllable word, including common ones like "another" or "beautiful".
  • A SMOG score of 6 does not mean "6 years old" — it means "6 years of schooling completed".
