Measurement, Evaluation, Assessment and Statistics
Test and Measurement The heart of kinesiology. Why? Test – tool or instrument used to make a measurement. Measurement – score on a test. Quantitative and assigns a number to a performance. (qualitative?)
Evaluation and Assessment Eval – interpretation of the measurement. Gives it meaning. Prescribe – correct any deficits. Assessment – the process of measure, eval, identify and prescribe. Skills or health related measures.
Reasons for Measurement and Evaluation Motivation Study material Practice skills Prepare for post-test Diagnosis Assess strengths and weaknesses Determine baseline Skills vs fitness levels Prescription
Reasons for Measurement and Evaluation cont… Classification Group students Homogeneous vs heterogeneous Control intensity of exercise or knowledge Achievement Progression of objectives and student Effectiveness of program Determine grades Subjective vs objective
Reasons for Measurement and Evaluation cont… Evaluation Instruction and program Compare two groups or methods Prediction Future performance Research (systematic in-depth analysis of a question) Determine grades Subjective vs objective
Statistics Organization and analysis of numerical data. Simple arithmetic and algebra. Must follow the steps. Add, subtract, multiply and divide.
Statistics cont… Analyze and interpret data Provides meaningful evaluation Interprets scores relative to one another Understand research Professional journals Practice their conclusions Essential for your continued growth in the field Do not believe everything you read.
Statistics cont… Standardize scores Units differ among tests Standardization allows comparison (SAT) Determine worth of a test Validity and reliability Continuum Consider the appropriateness of a test
Descriptive Stats Data – result of the test or the scores. Variable – dependent characteristic or what you are measuring. Population – all subjects. Sample – subgroup of the total population. Random sample – everyone has an equal opportunity to be included.
Descriptive Stats cont… Statistic – values from a sample. Descriptive – stats describe the sub-group only. Inferential – projections to a larger population. Discrete – whole numbers only. Continuous– broken down by decimal place.
Scales Nominal – code scoring with no quality comparison between groups. Ordinal – rank scoring from highest to lowest with no comparison of scores. Interval – no absolute zero but distance between scores is measured. Ratio – absolute zero and measured distance between scores.
