Test 1 Flashcards
Measurement
Process of assigning a number to a performance or attribute of a person
Criteria for determining a good test
Validity
Reliability
Objectivity
Administrative Feasiability
Procedure to assess health-related physical fitness
Plan
Assess
Analyze
Improve
4 Steps of Risk Classification
- Use logic model (a. Known diseases b. signs & symptoms of diseases c. # of CVD risk factors)
- Assess recommendations
- Evaluate other health issues
- Start assessment
Scales of Measurement
Nominal Scale
Ordinal Scale
Interval Scale
Ratio Scale
Interval Scale
Temperature, year, IQ, attitude
Distance between divisions same
No true zero point
Ordinal Scale
Ranking (i.e. best to worst, body size, etc.)
No determination can be made of the relative differences from rank to rank
Ratio Scale
Height, weight, distance, time, HR, BP
Possess all characteristics of interval scale
Nominal Scale
Divisions by gender, level, yes/no
Fundamental Principles of Assessment
Measurement
Test
Evaluation
Assessment
Reasons for Principles of Assessment
Motivation, Diagnosis, Classification, Achievement, Evaluation, Prediction, Research
Statistics
Collection, organization, analysis of numerical data
Uses symbols, terminology, and techniques
Value of Statistics
Analyze/Interpret data
Interpret research
Determine worth
Standardize test scores
Components of Preassessment Screening (PAS)
Informed Consent
Risk Classification
Informed Consent
Associated risks of conducting health-related fitness assessment range from no risk to high risk
Data
Result of measurement
Variable
Trait or characteristic
Population
Includes all subjects
Sample
Part of subgroup of population
Parameter
Value of measured characteristic that refers to population
Descriptive Statistics
Generalize methods used to describe the group
Inferential Statistics
When random sample is measured and projections/generalizations are made about a large group
Why is risk classification necessary?
To determine whether or not it is safe for an individual to be participating in assessment
How to proceed to assess health-related physical fitness (describe first & second step in detail)
- Informed consent - understand risk, allow consent, etc.
2. Risk classification - health hx, eval, risk level
Process of Informed Consent
- Read entire form
- Review key elements of assessment
- Emphasize client responsibility
- Ask questions
Essential Steps of Informed Consent
- Purpose
- Procedures
- Risks/discomforts
- Benefits
- Responsibilities
Reasons for Pre-Assessment Screening
To determine risk factors and health status
3 Levels of Risk
Low (<2 risk factors)
Moderate (2+ risk factors)
High (Known disease or shows major signs of disease)
How can physical activity be measured?
Subjective- questionnaires, diaries, logs
Objective- motion sensors,
Contraindicators for exercise testing
Cardiovascular disease
Pulmonary disease
Metabolic disease
Define a test
A tool or instrument to make a particular measurement
