Quantitative design

Quantitative design

1. Quantitative research characteristics

   • Structured tools
   • Sample size
   • Close-ended questions
   • Prior studies
   • Quantitative data
   • Generalization of results

2. Advantages of Q.R.

   • Collect reliable and accurate data
   • Quick data collection
   • Wider scope of data analysis
   • Eliminate bias

3. Techniques and types of study

   • Survey research
     • Ask questions
     • Big organization to understand their costumers
     • Analysis of collect data
     • Multiple question
     • Numerical results
     • Specific audience
     • Comparative analysis
     • Survay made face-to-face or by phone call
   • Cross-sectional survey
     • Observational surveys
     • Conducted situations by the researcher
     • Evaluate the variables at a particular time
   • Longitudinal
     • Observational surveys
       • Conducted across various time durations to observe
     • Different variables can be analyzed at different intervals of time
     • Used mostly in the medicine field and applied sciences
   • Correlational research
     • Comparison between 2 entities is invariable
     • Stablish a relationship between 2 entities
       • How impacts the other
       • what are the changes that observe
     • Give natural value to naturally occurring relationships
     • Needs 2 different groups
     • It's possible to correlate 2 or more variables
       • Using mathematical analysis methods
     • Research manipulate the variables that are conected to the results
   • Causal-comparative research
     • Depends on the factor of comparison
     • Also called Quasi-experimental
     • Conclude cause-effect equation between 2 or more variables
       • One variable is dependent
       • The other is independent
     • Independent variable = not manipulated
     • Dependent variable = is observed
     • The variable groups must be formed as they exist
       • In the natural set up
     • Always exist in group
     • Conclution are carefully establish keeping in mind all the factors

4. Experimental research

   • True experimentation
   • Based on 1 or more theories
   • Hasn't been in the past is simply supposition
   • Done around proving or disprovinf the statement
   • Used in natural sciences
   • The statement could be verified or refuted
   • Statement= efforts are made to understand if it's valid or invalid
