Research Methods and Sampling Techniques

Primary research means collecting your own fresh data through questionnaires, interviews, or observations. Secondary research involves using data that already exists, like government statistics from the ONS or previous studies by other researchers.

When choosing your sample, you've got several options. Random sampling gives everyone an equal chance of being selected - imagine picking names from a hat. It works brilliantly with large populations but can accidentally become biased if you pick too many people from one group.

Systematic sampling involves choosing every 5th, 10th, or 20th person from a list, making it dead easy to carry out. Snowball sampling happens when participants recommend others - like a snowball gathering snow. This saves time but creates bias since people tend to suggest others who think like them.

Quick Tip: Always consider whether your sampling method will give you a representative group that reflects the wider population you're studying.

Ethnography takes a completely different approach - it's about studying groups of people in their natural environment over long periods. Think of it as becoming a temporary member of the community you're researching to understand their daily lives and culture from the inside.
