Chunk Two Flashcards
outcome measure
objective evaluation of the influence of interventions on the client’s performance
when possible and applicable, measurement should be taken at the beginning, during, and at the end of intervention
advantages of standardized testing
scores can be understood by interprofessional team
tools are often widely available
uniform administration, scoring, and interpretation of results
can help monitor progress over time
can contribute to quality improvement adn evidence-based practice
disadvantages of standardized testing
must be combined with qualitative and other assessment methods to complete a comprehensive evaluation
multiple internal and external variables can impact performance on test and affect results
rigidity of administration may negatively influence the results
standardization sample
a large sample of people who represent the intended population for a test
referred to as a norm group
standard score
a score used in standardized testing, also referred to as z-values and z-scores that is used to make comparisons across variables and across population or individuals
scales of measurement
classification system used for quantifiable data
nominal
ordinal
interval
ratio
descriptive statistics
provides insight into the general characteristics of data collected during a study
measure of central tendency
measure of variability
measures of central tendency
a value that describes the center point of a data set
mean median
mode
mean
a measure of central tendency, also known as an average score, that is calculated by finding the sum of all scores within a data set then dividing the sum by the total number of scores in teh data set
median
a measure of central tendency, also referred to as middle value, that is determined by placing all scores in numerical order and locating the number in the middle
mode
a measure of central tendency that refers to the value that occurs most frequently within a data set
measures of variability
the statistical value that represents how much the group varies from the mean, and the degree to which the data spreads across the distribution
variance
standard deviation
standard deviation
measures the distribution and variation of data points around the mean
error variance
factors or variables that cause a difference in standardized test scores:
environmental conditions, motivation, fatigue
developmental index score
score used in developmental testing with the following features:
mean score is 100
standard deviation of 15 or 16
intervention often beneficial if scores are 2 standard deviations below the mean
deviation IQ score
scores used for measurement of intelligence with the following features:
mean scores is 100
intellectual disability is considered 2 standard deviations below the mean
age-equivalent score
a score that compares a child’s performance to others in the same age range
chronological age
age of an individual since birth that is calculated by subtracting birth date from current date
corrected age
age calculation also referred to as adjusted age, that is applied to premature infants to consider achievement of developmental milestones
age is calculated by subtracting the weeks of prematurity from chronological sage
grade equivalent
a score that compares a student’s performance to a normative group of students at the same academic level
