Closed = limited response but quick eg likert scale
S&W of open q
S= details of thoughts, unrestricted by categories, unexpected findings
W= wide range so diff to draw conc, interpretation may require subjective reasoning
S&W of closed q
S= easy to analyse and compare, objective
W= not precise, ranked scale may lead to same responses, oversimplified
Interviews
Gather more detailed info
Types of intv

Sampling
Large sample= acc estimate ABT nature of pop
Balance betw rep ACC target pop and time and money
Random
Every person has equal chance of being selected eg lots in a hat
Strength= high pop validity as Inc chance of rep sample
Weakness= more effort and time and doesn’t guarantee a sample
Opportunity
Use people available or known
S least amt prep
W low pop v due to sample being less rep
Stratified
Proportionately represented
S most rep, generalised
W could lead to bias as not all subgroups are not accounted
Volunteer
Replying to adv so taking part themselves
S convenient, specialised group of ppt
W majority of target pop may not respond to adv, ppt may not rep target pop so bias and not generalisable
