    What Is a Research Problem?

    • Any question that you want to answer
    • Any assumption or statement that you want to challenge or investigate or examine
    • a research problem/topic for a study.

    Sources of Research Problems

    • Personal/practical experience/observations
    • Critical appraisal of published scientific literature
    • Previous research
    • Social issues
    • Environments that stimulate an open interchange of ideas (scientific sessions, conferences, seminars)
    • Consultation with experts

    • Brainstorming
    • The world is teeming with questions and unresolved problems.
    • If there is no problem, there is no research.

    Conditions for a Researchable Problem

    • Perceived differences between 'what is' and 'what should be'.
    • Unclear reasons for the difference or discrepancy.
    • The existence of two possible, reasonable answers.

    Example Problems

    • Is there any relationship between sleep quality and academic performance?
    • What are the effects of TV programs on children's behavior?
    • What innovative strategies can we develop to overcome barriers in integrating mental health support into primary care?

    • Dependent variable
    • Moderator variable
    • Control variable
    • Intervening variable

    Hypotheses

    • A hypothesis is a tentative assumption made in order to draw out and test its logical or empirical consequences.

    • Questionnaires (mailed, collective, online)

    Primary vs Secondary Data

    • Primary data is collected afresh and for the first time.
    • Secondary data is data that is already available.

    Advantages of Primary Data

    • Better data interpretation
    • Addresses targeted issues
    • More efficient use of resources
    • Greater research control
    • Increased accuracy (of data)

    Disadvantages of Primary Data

    • The extent to which the characteristics of the sample accurately reflect the characteristics of the population.
    • Extremely important when the researcher wants to generalize from the sample to the target population/entire population

    Sampling Error

    • The extent of variation between an estimate obtained from a sample and the true value of the population.

    Sampling Bias

    • Over- or under-representation of a segment of the population that impacts study validity.
    • Caused by the researcher when samples are not selected carefully (e.g. time of year, place, language used, or researcher personal views influence data)

    Types of Sample

    • Representative sample
    • Unrepresentative sample

    Sampling Techniques

    • Probability sampling
    • Non-probability sampling
    • Simple random sampling
    • Systematic sampling
    • Stratified random sampling

    • Quota sampling
    • Purposive sampling
    • Snowball sampling

    Criteria for Selecting Sampling Method

    • The research objectives
    • Population of interest
    • Data collection techniques
    • Ethical considerations
    • Time and resources available
    • Sampling error

    Important Considerations
