Study Notes
Types of Tests
- Aptitude tests measure a person's potential for learning or acquiring skills.
- Achievement tests measure a person's previous learning.
- Speed tests measure a person's ability to complete a task within a certain time limit.
Correlation Coefficients
- The Spearman rank correlation coefficient is used when both data are ordinal.
- The point-biserial correlation coefficient is used when one datum is nominal and the other is interval.
- The biserial correlation coefficient is used when both variables are artificially dichotomous.
- The phi coefficient is used when both variables are dichotomous and at least one of them is a true dichotomous variable.
Intelligence and Mental Testing
- Alfred Binet is considered the Father of Mental Testing.
- The Stanford-Binet Intelligence Scale was developed by Lewis Terman and introduced the concept of Intelligence Quotient (IQ).
- The formula for calculating IQ is IQ = (MA / CA) * 100, where MA is Mental Age and CA is Chronological Age.
- The Simon-Binet Intelligence Scale was developed by Alfred Binet and introduced the concept of Mental Age.
Scales of Measurement
- The interval scale has the properties of magnitude and equal intervals.
- The ratio scale has an absolute zero and represents the absence of the variable being measured.
- The ordinal scale allows you to rank individuals but not to say anything about the meaning of the differences between the ranks.
- The nominal scale is heavily used when data is qualitative rather than quantitative.
Classical Test Theory
- The theory assumes that errors of measurement are random and unbiased.
- Charles Spearman is considered the Father of Classical Test Theory.
- The formula for calculating the standard error of measurement is SEM = σ / √(1 - r).
Regression Analysis
- The formula for calculating the predicted value of Y is Y' = a + bX.
- The coefficient of determination (r^2) is equal to 1 - (Syx / σ).
- The formula for calculating the coefficient of alienation is k = √(1 - r^2).
- Multiple regression analysis is appropriate when there are multiple independent variables.
Other Key Concepts
- Fechner's Law states that the strength of a sensation grows as the logarithm of the stimulus intensity.
- Hermann Rorschach developed the Rorschach inkblot test in 1921.
- Factor analysis is a method used to find the minimum number of dimensions (characteristics, attributes) called factors, to account for a large number of variables.
- The t-test is used to evaluate the relationship between two variables in the population using frequency data from a sample.
- The interquartile range represents the difference between the 75th percentile and the 25th percentile.
- Norm-referenced tests are used to compare an individual's score to a larger sample of scores.
- The principle of least squares in regression analysis is used to find the best-fitting line that minimizes the sum of the squared errors.
