Collecting Data

Collecting Data

Choosing Your Data Source

Be clear about the context of your investigation. This will shape the type of data you need.
Identify your population of interest - the group about which you want to make conclusions.
Select appropriate data sources. This could be primary (data you collect yourself) or secondary (data collected by someone else).

Methods of Data Collection

Familiarise yourself with different methods of data collection - surveys, experiments, observations, etc.
Choose the method that is most suitable to your research question and most feasible given your resources.
Always consider the accuracy, bias and representativeness of the data obtained through various methods.

Sampling Techniques

Understand sampling techniques like random, stratified, systematic, and convenience sampling.
Choose a sampling technique that achieves the best balance between minimising bias and practicality.
Remember that random samples are generally the most unbiased, but may not always be feasible.

Collecting the Data

Formulate a clear and concise data collection plan.
Ensure the data collected is relevant and sufficient to answer your research question.
Pay careful attention to record the data correctly and systematically for future analysis.

The Role of Ethics

Address any ethical considerations such as privacy, confidentiality, and informed consent.
Be aware of response bias and ensure steps are taken to minimise its impact.
Ensure ethical considerations are accounted for throughout the entire data collection process.

Quality of Data

Depict your data visually to aid understanding and see any patterns or anomalies.
Use statistical techniques to examine the data and gain deeper understanding.
Always be aware of the limitations in your data, and consider how they may affect your results and conclusions.

Remember, collecting data meticulously and ethically is paramount in any investigation. It provides the foundation for all later analysis and conclusions.
