Document Summary
Theoretical: health problems health services (general statement of relationship that is vague, terms, things, words, proposition, premises) Conceptual: adhd health problem (types, versions, hypothesis) Operational: mph prescriptions emergency care, audiology, alternative care, critical care (variable, use of measurements, prediction, result: different provincial healthcare operational system. Probability of healthcare being similar but not generalizable to others. Most incorporate equal chance of inclusion : remember measurement error. Any deviation in the observed value of a measure from the actual or true value of underlying value . Can be random: uncontrollable inaccuracies/fluctuation inn measures in which muddies result. Can be systematic: regular and repeated through over/underestimation: sampling error. Any deviation/difference in characteristics of a study sample from true characteristics of the overall population under study . Random error: i. e. uncontrollable error, people not showing up for school because of ramdan. Systematic error: i. e. every 5th person is included: sampling error of estimate.
