Study Notes
Primary & Secondary Data
- Primary data is collected directly from the source (e.g., surveys, experiments, observation).
- Secondary data is collected from existing sources (e.g., reports, databases, published research).
Qualitative Data Collection Methods
- Interviews: Gathering insights through structured or unstructured conversations.
- Focus groups: Facilitated discussions with a group of individuals to gather collective perspectives.
- Observations: Observing and recording behaviors, events, or phenomena.
- Case studies: In-depth analysis of particular individuals, groups, or situations.
Importance of Sampling
- Sampling helps to reduce the time and cost of data collection.
- It allows researchers to draw inferences about a larger population based on a representative sample.
Data Collection in Surveys & Experiments
- Surveys use questionnaires to collect data from a sample of individuals.
- Experiments involve manipulating one or more variables to observe their effects on other variables.
Challenges in Data Collection
- Data accuracy: Ensuring the quality and reliability of collected data.
- Data bias: Avoiding systematic errors that could influence the results.
- Missing data: Dealing with incomplete or missing information.
- Ethical considerations: Respecting privacy, confidentiality, and informed consent.
