Answer point one--------------------------Sampling, data collection, and data analysisSampling refers to the process used to select a portion of the population for study. Qualitativeresearch is generally based on non-probability and purposive sampling rather than probabilityor random approaches.3 Sampling decisions are made for the explicit purpose of obtaining therichest possible source of information to answer the research questions. Purposive samplingdecisions influence not only the selection of participants but also settings, incidents, events,and activities for data collection. Some of the sampling strategies used in qualitative researchare maximum variation sampling, stratified purposeful sampling, and snowballsampling.3Qualitative research usually involves smaller sample sizes than quantitativeresearch.4Sampling in qualitative research is flexible and often continues until no new themesemerge from the data, a point called data saturation.Many data collection techniques are used in qualitative research, but the most common areinterviewing and participant observation.5 Unstructured interviews are used when theresearcher knows little about the topic, whereas semi-structured interviews are used when theresearcher has an idea of the questions to ask about a topic. Participant observation is used toobserve research participants in as natural a setting as possible. The types of participantobservation range from complete participation to complete observation.5
