LECTURE 3 - overview of research methodology (2)

Question 1

Quota sampling

Answer 1

strategy in which various strata are identified by the researcher who ensures that these strata are proportionately represented within the sample to improve its representativeness

Question 2

Purposive sampling

Answer 2

strategy in which participants are selected on the basis that they are considered to be typical of a wider population

Question 3

Snowball sampling

Answer 3

strategy through which the first group of participants is used to nominate the next cohort of participants

Question 4

Convenience sampling

Answer 4

strategy that uses the most conveniently accessible people to participate in the study

Question 5

Data collection methods (5)

Answer 5

• Questionnaires
• Interviewing
• Observation
• Focus groups
• Unobtrusive measures

Question 6

Unobtrusive measures

Answer 6

data collection method that do not involve direct contact with participants and does not require the researcher’s presence

Question 7

Identifying physical measures (4)

Answer 7

• Natural accretion measures
• Controlled accretion measures
• Natural erosion measures
• Controlled erosion measures

Question 8

Natural accretion measures

Answer 8

Accretion takes place where there is a build up of deposits of materials or evidence. Not interested in these materials themselves, but what they might reveal about aspects of human behavior

Question 9

Controlled Accretion Measures

Answer 9

Researcher tampers with the materials that are concerned to the accretion comparison (glue on pages to see if they have been openend)

Question 10

Natural erosion measures

Answer 10

Degree of selective wear or deterioration on the material being studied (wear and tear carpet to see human traffic)

Question 11

Controlled erosion measures

Answer 11

It is possible to manipulate the extent to which something wears out against some other experimental variable
