1
Q

Confounding Variables

A

Variables related to IV which do effect the DV so the researcher cant be sure whether the IV effected the DV or whether it was just the confounding

Q

Qualitative data

A
  • Data can be gathered in two ways, one of which is descriptive data (qualitative) using things like open ended questions in surveys

Q

Non-experimental designs vs experimental designs

A
  • Non-exp designs ask ‘what?’ questions to assess what is happening and ask open ended questions + test predictions
  • Exp designs ask ‘why?’ questions to assess why something has happened (causation) and try control affecting factors

Q

Observations

A
  • Filled w/ descriptive data
  • Naturalistic Observation: Takes place in a place where the behaviour would naturally occur + attempts to categorise behaviour + cause minimal disturbance
    e. g: looking at feeding behaviours of fussy children at someone else’s house (they will act different around a unknown person)

Q

Problems with observational research

A
  • Lack of computer reliability of categorisation > researchers interpretation of observed behaviour may be biased > can be resolved by increasing inter-rater reliability
  • Reactivity bias: if a new person is included in a situation they aren’t usually in, the person being studied may react differently > can be solved by using a participant observation (e.g: studying a child w/ autism by asking the parent to observe frequency of certain behaviour)

Q

Case studies

A
  • In depth observation and research of an individual (e.g a child with autism or in the care system or HM memory)

Q

Problems with case studies

A
  • Generalisation is an issue > cannot generalise to others as they way the event or person develops may not occur w/ others > could just be a unique case
  • can it be replicated? > can’t necessarily be replicated as the study is specific to that individual
  • cause and effect: can’t be certain that a certain variable causes a particular outcome, other factors in the person’s life may impact the outcome > can be overcome by correlating two similar studies

Q

Problems with surveys

A
  • memory of ppts may be an issue > if they are asked a question about an event which has occurred, their memory will impact how it is recalled
  • reactivity > participants will know the results are being analysed + may try guess the hypothesis so act in a particular way due to social pressure
  • questionnaire validity > is it measuring what is claims to? could compare answers to resolve but is nebulous + may impact data analysis

- Multiple choice questions or ratings used

Q

Benefits of structured interviews

A
  • Easily quantified, the data is easy to use and analyse
  • Good comparability across participants as the same test is used thus same experience.
  • Can ensure all topics are covered as it is set beforehand

Q

Problems with structured interviews

A
  • Rigid structure with no room for flexibility
  • Not adaptable to the ppt which means only the surface information is achieved and cannot get a greater understanding which may make results more reliable.

Q

Unstructured interviews

A
  • Number of topics without fixed order or questions
17
Q

Benefits of unstructured interviews

A
  • Can gather more in depth information so get a greater understanding of the ppt.
  • Can make the questions bespoke and relevant to the participant
18
Q

Cons of unstructured interviews

A
  • Cannot generalise data as different further questions were asked
  • Analysis is time consuming as different questions were being asked across all ppts
19
Q

Overall advantages of descriptive research

A
  • Sometimes this is the only method of study both practically and ethically.
  • It is often inexpensive and flexible > quite easy to do
  • Real life studies and avoid manipulation so it is ethical
  • Has ecological validity (close to real life)
20
Q

Overall disadvantages of descriptive research

A
  • Researcher bias is easier
  • Reactivity > people may react differently because a researcher is present
  • Lack of cause and effect conclusions (why is this happening?)
21
Q

Correlational research & it’s purpose

A
  • To determine the relationship between two variables without manipulating them. This is done by measuring two variables which you think may be linked. > EG genetic history and heart disease.
  • Also looks at direction and strength of relationship among variables.
  • Variables must be quantifiable and measurable.
  • Statistical method for correlational research is correlation analysis > eg: measuring how often violent tv shows are watched and level of aggression.
22
Q

Problems with correlational research

A
  • Direction of relationship is often unclear
  • Confounding variables may be present as well.
  • EG: relationship between shyness and daydreaming > What leads to what? And other variables such as introversion may play a role. > there may be a correlation but that does not mean the relationship is causal.
23
Q

Correlational study vs descriptive study

A
  • A correlational study can be more informative as a they look at the degree of the relationship between two variables + can make predictions about this (positive + negative correlation)
  • Relational study can also identify + quantify relationships however this isn’t a proof of causality.
