Study Notes

Quantitative Research

  • This test covers various aspects of quantitative research design, data collection, analysis, and report writing.
  • Multiple-choice questions assess knowledge of different research methodologies, sampling techniques, data collection tools, validity/reliability, statistical tests, and report components.

Research Design

  • Ex post facto design explores how one characteristic/trait affects a dependent variable.
  • Experimental research involves manipulating the independent variable to observe its effect on the dependent variable.
  • Sampling in quantitative research requires representative samples, with a sample size large enough to reflect the population.
  • Stratified sampling differs from cluster sampling – the latter uses geographic or similar characteristics to select samples, while the former uses subgroups.
  • Systematic sampling involves selecting every nth item from a sampling frame, determining an appropriate sampling interval.

Data Collection Tools

  • Quantitative research often uses structured questionnaires (easier to standardize, interpret objectively, and code).
  • Recall-type questions can be asked in various formats, including fill-in-the-blank, multiple-choice, or true/false.
  • Validity and reliability of data gathering tools are crucial; a reliable instrument is usually valid, but not always vice versa.
  • Different types of validity tests include Content, Face, Construct and concurrent validity.
  • Data collection tools should be appropriate for the research question. (e.g., Observation, Interview)

Data Analysis

  • Data analysis needs to include the appropriate statistical test for the question.
  • Sociodemographic data (gender, age) analysis often relies on frequency counts, means, and percentages.
  • Hypotheses are tentative answers to research problems, formulated for inferential research questions
  • Level of significance is a threshold for determining if results are statistically significant (e.g., 0.05).
  • Research design explains how the research will be conducted, including data collection methods and procedures. This section of the research paper outlines steps for data collection.
  • Appropriate response formats should match the question types, (e.g., agreement scales, ratings, frequency scales, or descriptive words like excellent, quality).
  • Conclusion write-ups should be in past tense.
  • Statistical tests to consider for different types of research questions. (e.g., chi square, Pearson r, Spearman rho, t-test)

Research Report

  • The research report outlines the procedures for data collection.
  • Various aspects of the research methodology are included, depending on the specifics.
  • The appropriate format for presenting and interpreting data, including graphs and tables, is critical for effective communication.
  • Statistical significance is assessed to determine if observed differences are due to the intervention or chance.

Ethics and Research

  • Consent is required for human participants, especially minors in research.
  • Researchers should consider participants' well-being and ensure ethical data collection practices.

General

  • Instruments to record data should be tailored to the nature of the data. (Interview, Observation, Questionnaire, Tests)
  • Multiple-choice questions covering various aspects of research.
  • A strong emphasis on different types of validity, reliability, and ethical considerations.
