Cheat Sheet
- Wechsler Scale and IQ Formula -
The Wechsler Adult Intelligence Scale (WAIS) sets the average IQ at 100 with a standard deviation of 15, using the formula IQ = 100 + 15·Z. Mnemonic: "Mean of 100, ±15" helps you recall the core structure of most modern IQ tests. This standardization ensures consistency across diverse populations (source: American Psychological Association).
- IQ Score Categories and Percentiles -
To answer "what is average IQ?" remember that an average IQ score ranges from 85 to 115, capturing about 68% of test-takers. Categories include borderline (70 - 84), average (85 - 114), high average (115 - 129), and gifted (130+), with percentiles aligning to these bands (source: APA).
- Interpreting an IQ of 145 -
An IQ of 145 places you above the 99.7th percentile, often classified as "highly gifted" and well above the Mensa cutoff of approximately 130. This means exceptional problem-solving skills and reasoning ability compared to the general population (source: Mensa International).
- Reliability and Validity of IQ Tests -
Modern IQ assessments demonstrate test - retest reliability coefficients above 0.9 and strong validity through correlations with academic and occupational success (r ≈ 0.5 - 0.8). These psychometric properties ensure that IQ scores meaningfully reflect cognitive ability (source: Journal of Educational Psychology).
