What is a survey?
gathers information by asking questions of a large number of people, using written questionnaires and/or interviews
Gathering data:
How the Q's are asked is important
Face to face encounter, or phone, asking Q's and recording info.
Written set of Q's, they write and then return to you, both have open/closed Q's.
Designing surveys:
1: Q's must be worded well so participant get what you mean. A shared understanding is needed to = valid.
2: How the Q's are asked, consider time to analyse and answer Q's. people could give up if to many Q's and if allot of the Q's are open, the
data is huge and very time consuming for analysis.
3: Consider sample, size and who it represents. Many people need to be chosen, and those chosen need to represent wide population
4: use a pilot study, tests for clarity and allow the surveyor to make sure all needed info is gathered.
Response set or response bias =
the tendency to stick to one response through the way the questions are asked. Qs should be set up to achieve a range of responses.
Negatives in Qs ­ should not be used, may confuse the participant.
Lying in Questionnaire ­
Social desirability:
some people may answer based on what is accepted in society, e.g some may say they are not racist as it is socially accepted
Demand characteristics :
may occur in quantitative data as the aim of survey can be guessed, participant may want to help out. Lowers validity…read more

questionnaires and interviews
Unstructured interview:
Gives qualitative data, with open Q's and flexible structure. There is a research question but the rest is unspecified to see how things flow.
Semi-structured interview:
A schedule of Q's but researcher can have freedom for open responses.
Structured interview:
Pre-set Q's, leaves little room for follow up Q's of interest
Interview ­ strengths
1: interviewer can explore answers and ask more Qs not limited like in questionnaires
2: The data achieved is in-depth and detailed, more likely to be valid
Interview ­ weaknesses
1: Subjectivity when it comes to analysis
2: Experimenter effect, can influence participants
Evaluation of questionnaires:
1: Valid ­ Qs can be sent by post removing researcher presence, removing experimenter effect and increasing validity
2: Reliability ­ can be repeated accurately as there are set procedures and same Qs asked to all participants, allows replication so = reliable
1: Reliability ­ way it administered can be different, different researchers ask different participants in different location may lower reliability
2: Validity ­ set Qs used, may give fixed answers, not true thoughts of individuals, they aren't free to say what they want, may lower validity.…read more

Methodology PG 3
A statement predicting result of an experiment.
Alternative hypothesis:
A hypothesis which is an alternative to the null
Null hypothesis:
states that predicted results are only achieved through luck/chance. When you research you test for the null, if it is rejected then you data
shows a real effect.
open question:
Can be answered in any way the participant chooses
Qualitative data: open Q's give this, where words describe views
increased validity, due to more In depth analysis of answers = better conclusion + Qualitative data can be broken down into quantitative,
but not vice versa
Difficult to draw compassions between groups or arrive at a reliable conclusion, + time consuming, difficult to analyse.
closed question:
Limits the response which can be made
Quantitative data: closed questions give this type of data, where data is reduced to figures and numbers.
Allow group analysis of data, easily draw conclusion between things. Increased reliability+ quick and easy to analyse
greatly superficial view is created due to limitation in answer, may lower validity + interpreting the Qs is subjective, "unsure" may mean
different things to different people so low validity again.…read more

Ethical issues:
Fully informed consent:
They should be told full aim of study, and what procedure will occur. Sometime not possible
E.G (Milgram) so, good debrief needed
Participants should not be deceived, however sometimes it may be necessary so they have to agree to do the test knowing that they will not be
told all the info
Right to withdraw:
Free to leave any time, can take/ destroy their data. If paid for experiment, they still keep $
Researcher must have the necessary qualifications, if in doubt they must seek advice and help from someone who is competent.
