Study Notes

Types of Norms

Raw test scores need to be converted into relative measures or derived scores for more meaningful comparisons
Derived scores show a person's relative standing on a test and allow comparisons between different tests
Developmental norms define typical patterns, age-specific tasks, and skills at different stages of development
Developmental norms assume age-appropriate abilities and establish norms for performance at specific ages
Mental age (MA) is a person's performance level compared to others of a similar age group
A child with MA of 13 can perform as well as most other 13-year-olds on a particular test
MA can be above or below the chronological age (CA) demonstrating intellectual strengths or weaknesses
Developmental norms aren't always easy to use as tests may measure different abilities and subtests may assess varying skill competencies
This makes comparisons difficult, as different tests and subtests might not yield similar MA scores
Mental age is commonly used through scales like Binet-Simon, where items are grouped by age-appropriateness
Mental age is calculated from basal age (highest age where all items are passed) and partial credits for items passed at higher levels
Mental age norms are also used with tests that aren't structured by age levels; using mean raw scores of specific age groups for comparison
Mental age norms are useful in identifying developmental differences and cognitive abilities

Grade Equivalents

Grade equivalents show the average performance of children who are at a particular grade level (e.g. 6th grade for the calculation of 6th-grade equivalents)
Grade equivalents are average performance levels at the beginning, middle, and end of a typical school year in standardized tests and represent performance levels relative to the standardized sample.
Grade units, while seemingly useful, aren't equal, and the importance of subjects differs throughout different grade levels
Grade equivalents provide limitations, reflecting only performance in tested subjects and don't always represent a true depiction of individual performance
Grade norms might inappropriately suggest the performance level of all or many students within a grade due to individual differences
Grade norms provide comparisons only for the subjects covered in the test, and not for other subjects
This issue is also prevalent when the test is on subjects only available for a certain time period in grade school etc.

Ordinal Scales

Developmental norms can emerge from child psychology research
Researchers observe and describe typical behavior patterns in infants and children at different ages (e.g., sensory skills and language development)
Example: Gesell Developmental Schedules assess a child's development in motor, adaptive, language, and personal-social areas based on age-based norms
Gesell's theory emphasizes sequential development patterns in children, with an assumption that stages follow a specific order

Within-Group Norms

Within-group norms are used by comparing a person's performance to others in the same age or grade group from the standardization sample
Percentiles describe a person's relative standing in a group. For example, a score at the 50th percentile means that 50% of the sample scored at or below that point
A 50th percentile score represents the median
Percentiles represent a precise location in a group, whereas percentage is a raw score value

Standard Scores

Standard scores express distance from the mean of a distribution in terms of standard deviations
Z-scores are a linear transformation of raw scores, subtracting the mean and dividing by the standard deviation
Z-scores can indicate how many standard deviations a score is from the mean (e.g., a z-score of 2 means the score is 2 standard deviations above the mean)
Normal standard scores are transformed to reflect a normal curve distribution
Normal scores can easily be converted to various forms

Deviation IQ

IQ (intelligence quotient) is calculated by dividing mental age (MA) by chronological age (CA) and multiplying by 100
Deviation IQ is a standard score with a mean of 100, derived from a distribution using a standard deviation (SD)
Deviation IQ compares people within the same age group and assumes a normal distribution of IQ scores

Relativity of Norms

IQ scores should reference the specific test used. Comparisons between different tests may not be meaningful.
Different tests measure different cognitive skills or abilities, thus should not be compared
Differences in standardized samples used can also misrepresent the relativity of norms
Standardized tests and samples may vary from their target groups.
