Study Notes
Skewness Coefficient
- Pearson's coefficient is the most commonly used method to calculate skewness.
- The formula to calculate skewness values: (mean - mode) / standard deviation.
- Pearson's first coefficient is helpful when the data presents a high mode.
- If the data exhibits low mode or multiple modes, Pearson's second coefficient is superior.
- Formula for Pearson's second coefficient: (mean - median) * 3 / standard deviation.
- Rule of thumb for interpreting skewness values:
- Between -0.5 and 0.5: approximate symmetry.
- Between -1 and -0.5 or 0.5 and 1: slightly skewed data distributions.
- Less than -1 or greater than 1: highly skewed data distributions.
Intelligence
- Social intelligence: the ability to react to social situations in daily life, including understanding people and acting wisely in human relationships.
- Examples of people with high social intelligence: leaders, salesmen, ministers, and diplomats.
Thurstone's Group Factor Theory
- Louis Thurstone (1937) proposed that intelligence is a cluster of abilities.
- He identified 13 independent factors, called primary mental abilities, using multiple factor analysis.
- The seven primary mental abilities are:
- Verbal comprehension
- Problem-solving
- Verbal fluency
- Deductive reasoning
- Spatial visualization
- Perceptual speed
- Inductive reasoning
Carroll's Three-Stratum Theory
- The theory differentiates factors or abilities into three strata based on the relative variety and diversity of variables.
- The three strata are:
- Stratum I: narrow or specific abilities (approximately 70 identified).
- Stratum II: broad abilities (e.g., Gf and Gc).
- Stratum III: the broadest or most general level of ability (general ability or g).
Fluid Intelligence (Gf)
- Refers to mental operations used when faced with a novel task that cannot be performed automatically.
- Includes forming and recognizing concepts, perceiving relationships, drawing inferences, and problem-solving.
- Hallmark narrow ability indicators of Gf: inductive and deductive reasoning.
- Other specific Gf abilities: quantitative reasoning (RQ).
Crystallized Intelligence (Gc)
- Refers to the breadth and depth of a person's acquired knowledge and skills valued by their culture.
- Includes declarative (static) knowledge and procedural (dynamic) knowledge.
- Declarative knowledge: factual information, comprehension, concepts, rules, and relationships.
- Procedural knowledge: process of reasoning with previously learned procedures to transform knowledge.
General (Domain-Specific) Knowledge (Gkn)
- Refers to the level of specialized knowledge a person has in a specific field.
- Developed through work experience, hobbies, or passions.
- Represents the "depth, breadth, and mastery of specialized knowledge" in a particular domain.
