PRACTICAL RESEARCH 2 QUIZ

• 1. is defined as the logical and coherent overall strategy that the researcher uses to integrate all the components of the research study.

  research design
• you are going to have a great deal of abstraction and numerical analysis

  quantitative research
• When little is known about the research problem, then it is appropriate to use descriptive research design


  descriptive reseach
• The main goal of this design is to determine if variable increases or decreases as another variable increases or decreases. This design seeks to establish an association between variables.

  Correlational Research
• In this design, the researcher has no control over the variables in the research study.

  Ex Post Facto
• The term means partly, partially, or almost – pronounced as kwahz-eye. This research design aims to measure the causal relationship between variables

  Quasi-Experimental
• This research design is based on the scientific method called experiment with a procedure of gathering data under a controlled or manipulated environment

  Experimental Research.
• is the totality of all the objects, elements, persons, and characteristics under consideration

  population
• This approach is founded on the principle of power analysis. There are two principles you need to consider if you are going to use this approach: these are statistical power and effect size.

  Power Analysis.
• It is a way of choosing individuals in which all members of the accessible population are given an equal chance to be selected.

  Simple Random Sampling.
• The same with simple random sampling, stratified random sampling also gives an equal chance to all members of the population to be chosen.

  Stratified Random Sampling.
• This procedure is usually applied in large-scale studies

  Cluster Sampling.
• This procedure is as simple as selecting samples every nth (example every 2nd, 5th) of the chosen population until arriving at a desired total number of sample size

  Systematic Sampling
• are basic tools researchers used to gather data for specific research problems

  Research Instruments
• A good research instrument is concise in length yet can elicit the needed data.

  Concise
• Questions or items must be arranged well. It is recommended to arrange it from simplest to the most complex

  Sequential
• The instrument should pass the tests of validity and reliability to get more appropriate and accurate information.

  Valid and reliable.
• his factor should be considered. Hence, before crafting the instruments, the researcher makes sure that the variable and research questions are established

  Easily tabulated
• 1. is defined as the logical and coherent overall strategy that the researcher uses to integrate all the components of the research study.
