Study Notes

Professional and Scientific Criteria

Professional data management relies on qualitative population norms.
Scientific data management is based on quantitative analysis.

Psychological Tests

Cutoff score for passing a psychological test is 75% (30 out of 50).
Scores of 29 and below indicate failure.
Tests can be categorized into speed tests with time limits and power tests with no time constraints.

Scoring and Standardization

Scoring reflects nomothetic data and utilizes systematic procedures for sample behavior acquisition.
Standardized tests aim for objectivity in the testing process.

Types of Indicators

Formative indicators demonstrate causal relationships, while reflective indicators show effects.
The standard error of a sample statistic represents the standard deviation of its sampling distribution.

Descriptive Use of Statistics

Descriptive statistics allow for using normal curve models to approximate distributions that deviate from normality.
Normalizing scores can align non-normal distributions to have equivalent positions to normal distributions through cumulative percentages.

Inferential Statistics

Inferential statistics estimate population parameters and test hypotheses about mean differences.
The standard error of the mean (SEM) is derived from the sample's standard deviation divided by the square root of the sample size.

Properties of the Normal Curve

The normal curve is bell-shaped and bilaterally symmetrical, with both halves representing equal areas.
Tails of the curve approach but never touch the baseline, extending to infinity.
It is unimodal, presenting a single point of maximum frequency.

Variability and Test Utility

Individual differences introduce variability necessary for the accuracy of psychological assessments.
Greater variability among individuals enhances the precision of distinctions made in testing outcomes.

Key Concepts of Normal Curve

The mean, median, and mode coincide at the center of the distribution.
The point of balance in the normal curve serves as the mean and divides it into two equal halves.
