1. Research Process

   • Make a problem statement
     • Create a research question
       • Create a research hypothesis
         • Operationalize measures
           • Design Experiment
             • Sampling Plan
             • Data collection Plan
             • Data Analysis Plan
               • three level of data comparison
                 • Univariate
                   • One variable influences
                 • Bivariate
                   • Two variable Influence
                 • Multivariate
                   • Many Variables influence
             • Knowledge Translation plan
               • Knowledge Dissemination
             • Obtain Ethic Board Approval
               • Test
                 • Generate a null hypothesis
                 • Disseminate
                   • Publish
                 • Translate
                   • Adapt, Implement and Evaluate
       • Includes the important variable of the research problem in ambiguous terms
       • The answer to the question is only as solid and specific as is the question
     • Research aim or objective
     • Describes what the situation is the requires changing or understanding
     • How the study will address this situation or problem

2. Apprasial

   • Worthy Topic?
     • PICO/PS
       • Population
         • Intervention
           • Comparison
             • Outcome
       • Independent (Predictor Variable)/Dependent (outcome Variable)
         • Reliable/valid
           • Appropriate method and plan
             • Internally valid?
             • Externally Valid?
             • Approved for ethic?
               • beneficence
                 • respect for person
                   • Justice
               • Appropriate accept/reject decision
                 • Clinically Significant?/impact?

3. Operationalize the measures

   • Reliability
     • The degree of consistency or dependability with which instrument measure the attribute it is intended to measure
     • Interrater
       • Different research test it, and get the same or similar results
     • Internal Consistency
       • 8 scale item (question), does each question all relate to depression?
     • Test-retest
       • Repeat the test (participates)
   • Validity
     • The degree to which a measurement instrument measure what it is intended to measure
     • Content Validity
       • Asking question if it relates to depression
     • Criterion Validity
       • Make new test, compare new and old test
     • Construct Validity
       • Compare the opposite test

4. Design: Sampling

   • Accessibility Population
     • Representative sample
       • sample has the same characteristics percentage of the whole population
     • Convenient sampling
       • going out and picking a student
     • Inclusion criterion
       • Exclusion criterion

5. Data collection

   • Self-report survey
   • interview
   • Observation
     • Hawthorne Theory
       • people improve ability when knowing that they are being observed.
