Study Notes
Research Problem
- A research problem identifies a perceived gap between the current situation and the ideal scenario.
- Effective research addresses situations with potential solutions; problems without solutions are less worthwhile for research.
- Three conditions qualify a problem as a potential research issue:
- A perceived discrepancy between the actual condition and the expected one.
- Inquiry into why the discrepancy exists.
- At least two possible answers to the posed questions.
Distinction of Problems
- Research problems require investigation and deeper questions, while non-research problems often have administrative solutions or existing answers.
- Key considerations for non-research problems include:
- Can it be solved via administrative changes?
- Are existing solutions sufficient?
- Is it a significant issue based on available data?
Aspects of Research Problems
- Study population includes individuals or groups providing essential information.
- Program subjects cover issues like population needs, satisfaction, and outcomes that inform research questions.
- Phenomena relate to studying cause-effect relationships and various phenomena itself.
Prioritizing Research Problems
- Relevance: Assess importance based on health and social consequences.
- Feasibility: Evaluate the practicality of conducting the research.
- Applicability: Determine if potential solutions are effective under ideal conditions.
- Cost-effectiveness: Analyze whether the resources invested yield worthwhile outcomes.
- Timeliness: Ensure that the findings are obtained promptly.
- Ethical considerations: Confirm ethical acceptance by the respondents.
Problem Statement Essentials
- Crafting a problem statement involves:
- Clearly articulating the problem.
- Justifying the necessity of the research.
- Analyzing the situation and its implications.
Research Objectives
- Objectives delineate the clear and specific goals of the study.
- They help define the research direction and can be categorized into three types:
- ‘What questions’ seek to define variables.
- ‘Why questions’ explore underlying causes.
- ‘How questions’ investigate methods for change.
Hypothesis
- A hypothesis posits a tentative relationship between variables, predicting specific outcomes.
- Characteristics include:
- It is provisional and not definitively proven.
- Often involves the relationship between two or more variables.
- Types of hypotheses:
- Research Hypothesis: Basis of investigation.
- Alternate Hypothesis: Specifies conditions that would be true if the research hypothesis fails.
Errors in Hypothesis Testing
- Errors in testing may arise from faulty study designs, sampling methods, data collection, or analysis procedures.
- Types of errors include:
- Type I Error: False rejection of a true null hypothesis.
- Type II Error: False acceptance of a false null hypothesis.
