QUANTITATIVE RESEARCH, HAMEDAH BINTI MAJELAN (66072) - Coggle Diagram

- - - - Variable to be related (must rationale)
      - logic one by theory or derived from experience
    - - Obtained from each member sample
      - Paired scores are the related
      - 2 more scored
    - - 30 participant & develop valid and reliable measures
    - - Decimal number
        
        near +1.00 - high size and (+)(direction)
        
        near -1.00 - high size and (-)(direction)
        
        near .00 - variable not related
      - Correlation coefficient (Indicates the size and direction of
        relationship
    - - below plus or minus .35 (low or not related)
      - prediction (below plus or minus (.50) - generally useless
      - higher than plus or minus (.65) - highly related
      - between plus or minus (.35 and (.65) - moderately related
      - Reliability (.90s - high, .80s - moderate, .70s - low
  - - - Data Collection
        
        obtain predictor variables
        
        strength - of the predictor variable is established
      - Data Analysis
        
        Prediction equation Y = a + bx
    - - Data Analysis
        
        Computing a correlation coefficient & linear relationship
      - Data Collection
        
        Identify population - select a sample
        
        Identify variable
- - - - Cross-Sectional Survey - collecting data from selected single
        time period
      - Longitudinal survey - collect t2 or more time to measure changes
        over time
    - - how data are collected
        
        Observation - Researcher obtain data by watching participant
        
        Self report instrument( questionnaire, IV)
    - - opinions
      - preferences
      - assessing attitudes
      - demographic
      - practices and procedures
  - - - Selecting a participants
      - systematic
      - simple random sampling
      - Brief statement
    - - avoid Jargon(specific)
      - Avoid leading Questions
      - avoid questions that assumes a fact not necessary true
      - avoid touchy questions
- - - - 2) measured before and after receiving the experimental treatmen
    - - Randomly assigned to all groups
    - - measured on the dependent variable
  - - - Deals with the extent of generality
        of the results
    - - Basic minimum of control measument, analysisi & procedures necessary to make the results of experiment interpretable
