Study Notes
Research Design
- Definition: Framework for collecting and analyzing data.
-
Types:
- Exploratory: Seeks to explore a problem when little is known.
- Descriptive: Describes characteristics of a population or phenomenon.
- Experimental: Tests hypotheses by manipulating variables.
Data Collection Methods
-
Qualitative Methods:
- Interviews: In-depth insights via open-ended questions.
- Focus Groups: Group discussions for diverse perceptions.
- Observations: Recording behaviors in natural settings.
-
Quantitative Methods:
- Surveys: Structured questionnaires to gather numerical data.
- Experiments: Controlled study for causal relationships.
- Secondary Data Analysis: Using existing data sets for new insights.
Qualitative Analysis
- Purpose: To understand concepts, opinions, or experiences.
-
Techniques:
- Thematic Analysis: Identifying patterns or themes within data.
- Content Analysis: Quantifying and analyzing the presence of certain words or themes.
- Grounded Theory: Developing theory based on data collected from participants.
- Data Representation: Use of narratives, quotes, and visual models.
Quantitative Analysis
- Purpose: To quantify the data and generalize results from a sample to the population.
-
Techniques:
- Descriptive Statistics: Summarizing data through mean, median, mode, etc.
- Inferential Statistics: Drawing conclusions using tests like t-tests, ANOVA, regression.
- Data Representation: Use of charts, graphs, and numerical summaries.
Statistical Sampling
- Definition: The process of selecting a subset of individuals from a population.
-
Types:
- Probability Sampling: Each member has a known chance of selection (e.g., simple random, stratified, cluster).
- Non-Probability Sampling: Selection based on subjective judgment (e.g., convenience, purposive).
-
Considerations:
- Sample Size: Larger samples reduce error margin but require more resources.
- Sampling Bias: Systematic error due to non-random selection leading to unrepresentative samples.
Research Design
- Research designs provide a framework for collecting and analyzing data.
- Exploratory designs are used when little is known about a problem.
- Descriptive designs aim to describe characteristics of a population or phenomenon.
- Experimental designs test hypotheses by manipulating variables.
Data Collection Methods
- Qualitative methods involve gathering rich, in-depth data.
- Interviews provide individual insights through open-ended questions.
- Focus groups facilitate discussions for diverse perspectives.
- Observations record behaviors in natural settings.
- Quantitative methods involve collecting numerical data.
- Surveys use structured questionnaires to gather data.
- Experiments control variables for causal relationships.
- Secondary data analysis leverages existing datasets for new insights.
Qualitative Analysis
- Qualitative analysis aims to understand concepts, opinions, or experiences.
- Thematic analysis identifies patterns or themes within data.
- Content analysis quantifies and analyzes the presence of words or themes.
- Grounded theory develops theory based on data collected from participants.
- Data representation includes narratives, quotes, and visual models.
Quantitative Analysis

- Inferential statistics draws conclusions using tests like t-tests, ANOVA, and regression.
- Data representation includes charts, graphs, and numerical summaries.
Statistical Sampling
- Statistical sampling involves selecting a subset of individuals from a population.
- Probability sampling ensures each member has a known chance of selection (e.g., simple random, stratified, cluster).
- Non-probability sampling relies on subjective judgement (e.g., convenience, purposive).
- Sample size influences accuracy, with larger samples reducing error margin but requiring more resources.
- Sampling bias arises from systematic error due to non-random selection.
