what are the 8 tests used to identify the level of significance ?
- sign test

what is the 3 parts of the criteria to justify using a sign test ?
- difference
- repeated measures

what does the calculated value need to be for a sign test to be significant?
equal to or less than the critical value
how do you work out the sign test’s calculated value ?
- find the + and -
- whichever is the one that’s less is the calculated value
what are the 3 parts of the criteria for Mann Whitney ?
- difference
- individual groups
- ordinal
what does the calculated value need to be in a Mann Whitney test for it to be significant ?
the calculated value needs to be equal too or less than the critical value
what are the 3 parts of the criteria for a Wilcoxon test ?
- difference between groups
- repeated measures
- ordinal data
what does the calculated value need to be in a Wilcoxon test to be significant ?
equal too or less than the critical value
what are the 3 parts of the criteria for a Chi-Squared test ?
- difference

equal too or more than the critical value
what are the 2 parts for the criteria for Chi-Squared test ?
- correlation
- nominal data
what are the 2 parts for the criteria for a Spearman’s Rho test ?
- correlation
- ordinal data
what does the calculated value for a Spearman’s Rho test need to be to be significant ?
equal too ore more than the critical value
what are the 2 parts for a criteria of a Pearson’s R test ?
- correlation
- interval data
what does the calculated value need to be in a Pearson’s R test to be significant ?
equal too or more than the critical value
what are the 3 parts for the criteria of a Unrelated t-test ?
- difference but between 2 sets of data
- individual groups
- interval data
what does the calculated value need to be in a Unrelated t-test to be significant ?
equal too or more than the critical value
what are the 3 parts for the Related t-test ?
- difference between 2 sets of data
- repeated measures
- interval data
what does the calculated value need to be in a Related t-test to be significant ?
equal too or more than the critical value
what is the order of the 6 aspects that a scientific journal includes ?
- abstract
- introduction
- method
- results
- discussion
- references
what is an abstract in a scientific journal ?
a summary that includes a brief description of the aims, hypothesis, procedures, main findings, conclusions and implication of the study
what is the introduction in a scientific journal ?
starts off with a review of other similar research, including theories that the research is going to be based on
- starts of really broad then becomes more specific to the research
- aim
- hypothesis
- null hypotheis
what is the method in a scientific journal ?
detailed description of what the researches did
- design
- pps
- materials
- producers
- ethics
what is the results in a scientific journal ?
- descriptive results
- critical value
- raw data
what is the discussion in a scientific journal ?
everything about what the results show
what is the references in a scientific journal ?
any references from articles, books and studies etc… must be refrenced
what 2 sections should a consent form include ?
- procedural issues
- ethical issues
what are the 6 procedural issues in a consent form ?
- specific details/ requirements
- non-invasive procedure
- the functioning is assed before and after
- researcher is trained to conduct
- duration of the procedure
- random allocation of pps in conditions ( if relevant)
what are the 6 ethical issues in a consent form ?
- no pressure to consent
- pps can withdraw at anytime
- pps can withdraw their data
- pps data will be kept confidential
- pps should feel free to ask questions
- receive a full debrief at the end
what 3 things must be included in standardised instructions for a scientific journal ?
- what will happen to the pps and what they need to do
- include a check of understanding
- possible to also remind them of their ethical rights
what must be clearly explained and the same in standardised instructions ?
- the instructions
- get the same instructions
what must be included in a debrief for a scientific journal ?
- aim of the experiment
- what the different conditions were
- explain any deception that was used and why
- what is expected to be found
- what is going to happen with the results
- ask if they have any questions
- remind them of the ethics
what are the 2 types of references that need to be known ?
- book
- journal
what is needed if referencing a journal article ?
surname, initials (year), title, journal title in italics, volume of italics, page numbers
what is needed when referencing a book ?
surname, initials (year), book title in italics, place of publication, name of publisher
what does designing a study need to include ?
- include all the details mentioned in the question
- the design needs to be completely relevant to the topic
what are the 12 things involved in the study pro-forma for design a study ?
- aims
- hypothesis
- variables
- extraneous variables and how to control
- sample and sampling method
- design
- method
- materials
- ethical issues
- results
- statistical analysis
- qualitative analysis
what are the 4 factors to consider when designing a study ?
- experiments
- observations
- self report
- correlations
- case study
