## What is the difference between a subject and a participant?

Participants, respondents and subjects are the people who the researcher selects for their study. 1. Participants are usually in qualitative research (eg. Subjects are usually in experimental/scientific research (quantitative).

### What are the different sampling techniques in research?

Methods of sampling from a population

• Simple random sampling. In this case each individual is chosen entirely by chance and each member of the population has an equal chance, or probability, of being selected.
• Systematic sampling.
• Stratified sampling.
• Clustered sampling.
• Convenience sampling.
• Quota sampling.
• Judgement (or Purposive) Sampling.
• Snowball sampling.

### How do you approximate a sample mean?

How to calculate the sample mean

1. Add up the sample items.
2. Divide sum by the number of samples.
3. The result is the mean.
4. Use the mean to find the variance.
5. Use the variance to find the standard deviation.

What is a sample population in research?

A population is a complete set of people with a specialized set of characteristics, and a sample is a subset of the population. The study population is the subset of the target population available for study (e.g. schizophrenics in the researcher’s town). The study sample is the sample chosen from the study population.
