Year 2 research methods Flashcards
What must a psychology report include?
Title, abstract, introduction, procedure, results, discussion, references and appendices
What is the title?
Must be concise, clear, gives the reader an idea of the investigations concerns
what is the abstract?
a brief summary of the investigation , written last, appears at the front
what must be included in the abstract?
a one sentence summary description of participants and sampling technique description of procedure description of results conclusion
what is the introduction?
a literature review of the general area of investigation
relevant theories, concepts and studies
logical progression - become more specific until aim and hypnosis are presented
What is the method?
Four sub-sections design and overview participants and investigators apparatus procedure
What is included in the design and overview?
research method used and why research design use and justified state iv and dv any other variables controlled how you delay with ethical issues
what is included in participants and investigators
who and how were they selected sampling procedure the investigator number of participants how they were allocated into groups
what is included in the apparatus and materials
a list of everything used
what is included in the procedure?
exactly what you did from start to finish
any pilot studies
refer to appendices for standardised instructions, debrief, copies of materials
a verbatim of everything said to participants
what is included in the results?
summarise key findings
summary table
fully labelled graph
do not include raw data
what is included in inferential statistics ?
were the results statistically significant?
is it possible to reject null hypothesis?
statistical test must be fully justified
what is included in the discussion ?
state findings in psychological terms, relating to aims and hypothesis
state whether findings support those of your background study
compare findings to existing research
what is included in the discussion of limitations and modifications ?
critical look at research strengths of study weaknesses of research look at confounding variables that could have affected the results suggest modifications
what is included in the discussion: implications and suggestions for further research?
suggest ideas for further research
real world applications and implications
What is included in references ?
background study
any internet resources
in alphabetical order
what is included in the appendices ?
raw data calculations stimulus materials standardised instructions debrief
what are descriptive statistics?
can not tell us whether the results are significant or not
measures of central tendency
measures of dispersion
graphs and tables
what are inferential statistics ?
refers to use of statistical tests which tell us whether the relationship found is significantly signficant or not
helps decide which hypothesis to accept and which to reject
what is probability ?
how likely the results are due to chance factors
what is the level of probability used by psychologists?
5%
0.05
what is a null hypothesis ?
any difference between the two conditions is caused by chance
what is a type one error?
occurs when a null hypnosis is rejected when it is in fact true
overly optimistic
more likely to occur when a less stringent level of significance is applied
what is a type two error?
occurs when a null hypothesis is retained when it is in fact false
pessimistic
more likely to occur when a more stringent level of significance is applied
When do you used a Chi squared test?
when it is a test of difference
unrelated data
nominal data
when do you use a sign test?
test of difference
related data
nominal data
when do you use a chi squared test (2)
test of correlation/ relationship
nominal
when do you use Mann-Whitney test?
test of difference
unrelated data
