Unstructured Interviews Practical Disadvantages: Time and Sample Size: takes a long time to conduct often several hours for each interview. - Limits the numbers that can be carried out which means researchers will have relatively small sample. -Time consuming = more costly

# data[].attributes.body
Reliable as they can be standardised, and controlled and repeated to get consistent results

# data[].attributes.body
Unstructured Interviews Reliability: Not reliable as each interview is unique. - Makes it virtually impossible for researchers to replicate the interview

# data[].attributes.body
Unstructured Interviews Validity: High in validity as it provides a true picture as we get more of what the interviewee thinks and their view/opinion

# data[].attributes.body
Not as valid as unstructured as it can produce a false picture as it is usually closed ended questions which are limited. Interviewees can't elaborate on their answers. Some people may lie or exaggerate

# data[].attributes.body
Unstructured Interviews Representativeness: Not very representative as unstructured interviews don't represent the whole community but individuals themselves

# data[].attributes.body
Quite representative as there is a high response rate due to being quicker than unstructured, so as a large number of people can be surveyed, findings can be generalised easier to the wider population

Unstructured: Practical Advantages- Rapport & Sensitivity: Informality of unstructured interviews allows the interviewer to develop a rapport (relationship of trust and understanding). - More likely to put interviewee at their ease. - Gives the interviewees view as there are no set questions.
