1 - Intervention

• In experimental research, the researcher decides the nature of intervention or treatment
• Intervention pertains to what is going to happen to the subjects of the study
• The decision covers who will receive the intervention and to what extent it will be applied to them
• Research data that appears measurable in numerical form is considered quantitative data
• Qualitative data can also be useful to quantitative research if given a numerical value
• Observation is gathering information about a certain condition using senses
• Researcher records the observation as seen and heard
• Data gathering through interview or questionnaire is done in a survey
• Observation can be done by direct observation or indirect observation using gadgets or apparatus
• An observation checklist aids the researcher in recording the gathered data
• Questionnaire uses series of questions or statements for respondents to answer
• Interview involves asking respondents orally for their responses
• Responses in quantitative research are expected to have numerical value, either nominal or ordinal
• Experimental design in a study uses treatment or intervention
• After subjects undergo the intervention, the effects of the treatment will be measured
• Data gathering procedure in research paper is presented in a paragraph format
• Contents include steps before gathering data, during data gathering, and after data has been gathered
• Suggested steps in gathering quantitative data:

  • Prepare research instruments
  • Identify involved authorities and ask permission
  • Determine sample size and corresponding respondents
  • Obtain consent form/parent’s consent form
  • Pilot test research instrument if needed
  • Clear instructions provided to respondents
  • Administer research instrument or implement research intervention
  • Collect, gather, or take note of responses
  • Summarize gathered data in a tabular form
  • Analyze summarized data corresponding to the research question
• Before

  • Prepare the research instruments.
  • Identify the authorities that will be involved and need to ask permission.
  • Determine the sample size and corresponding respondents; per group (if applicable).
  • Ask consent form/parent’s consent form.
  • Pilot test the research instrument if needed.
• During

  • Clear the instructions provided to the respondents.
  • Administer the research instrument or implement the research intervention (if applicable).
  • Collect or gather or take note of the responses.
• After

  • Summarize the data gathered, in a tabular form.
  • Analyze the summarize data corresponding to the data to the research question.
