• Delimitation


  The boundaries of the research study, based on the researcher's decision of what to include and what to exclude

• Dependent Variable


  A variable that varies due, at least in part, to the impact of the independent variable. Its value depends on the value of the independent variable
• Dependent Variable

• Framework


  The structure and support that may be used as both the launching point and the ongoing guidelines for investigating a research problem

• Hypothesis


  A tentative explanation based on theory to predict a causal relationship between variables
• Independent Variable


  The conditions of an experiment that are systematically manipulated by the researcher. A variable that is not impacted by the dependent variable, and that itself impacts the dependent variable
• Hypothesis


  A tentative explanation based on theory to predict a causal relationship between variables
• Margin of Error


  The permittable or acceptable deviation from the target or a specific value. The allowance for slight error or miscalculation or changing circumstances in a study
• Independent Variable


  The conditions of an experiment that are systematically manipulated by the researcher. A variable that is not impacted by the dependent variable, and that itself impacts the dependent variable
• Mean


  The average, calculated by dividing the sum of a set of data by the number of data points
• Margin of Error


  The permittable or acceptable deviation from the target or a specific value. The allowance for slight error or miscalculation or changing circumstances in a study
• Null Hypothesis


  The proposition, to be tested statistically, that the experimental intervention has "no effect". Meaning that the treatment and control groups will not differ as a result of the intervention

  The average, calculated by dividing the sum of a set of data by the number of data points
• Null Hypothesis


  The proposition, to be tested statistically, that the experimental intervention has "no effect". Meaning that the treatment and control groups will not differ as a result of the intervention
• Null hypothesis


  The hypothesis that the intervention has no effect
• Non-probability sampling


  • The selection of subjects or sampling units from a population using non random procedure
  • Examples: Convenient Sampling, Purposive Sampling
• Population


  The target group under investigation. The population is the entire set under consideration. Samples are drawn from populations.
• Questionnaire


  Structured sets of questions on specified subjects that are used to gather information, attitudes, or opinions
• Probability Sampling


  • The selection of subjects or sampling units from a population using random procedure
  • Examples: Simple random Sampling, Stratified random Sampling
• Random Sampling


  A process used in research to draw a sample of a population strictly by chance, yielding no discernible pattern beyond chance. Random sampling can be accomplished by first numbering the population, then selecting the sample according to a table of random numbers or using a random-number computer generator.
• Sample


  The population researched in a particular study. Usually, attempts are made to select a "sample population" that is considered representative of groups of people to whom results will be generalized or transferred.
• Statistical Analysis


  Application of statistical processes and theory to the compilation, presentation, discussion, and interpretation of numerical data.
• Triangulation


  A multi-method or pluralistic approach, using different methods in order to focus on the research topic from different viewpoints and to produce a multi-faceted set of data. Also used to check the validity of findings from any one method.
• Validity


  The degree to which a study accurately reflects or assesses the specific concept that the researcher is attempting to measure.
• Variable


  Any characteristic or trait that can vary from one person to another [race, gender, academic major] or for one person over time [age, political beliefs].
