| Question | Answer |
| what do you put in a hypothesis? | what is the IV what is the DV what do you expect to happen |
| experimental and hypothesis | experimental hypothesis- lab field or natural (or quasi) hypothesis (non experimental method used) interview, questionnaire, case study or observation. |
| types of hypothesis | directional hypothesis- one tailed- one predicted outcome. non directional hypothesis- two tailed- could be one of two outcomes. null hypothesis- nothing will happen |
| what three extraneous variables must be controlled? | participant variables situational variables investigator variables |
| what differences between participants are needed genralisability | age, gender, mood, ethnicity, expectations, intelligence, personality, memory, attitude, previous experience. |
| situational variables | the environment: heat/noise/distractions the time of day/time of year/place in history order effect- which part is done first |
| limit situation variables | do things in the... same order same time same equipment same surroundings |
| counterbalancing | ABBA group 1 do task A then task B group 2 do task B followed by task A |
| investigator variables | body language or tone made their mind up about the results demand characteristics |
| limiting investigator effects | placebo condition single blind double blind |
| testing reliability | test- retest reliability- same result when re-tested inter-rater reliability- same result when done by another researcher |
| 3 experimental designs | independent measures repeated measures matched pairs |
| sampling | random sampling systematic stratified opportunity volunteer |
| ethics | BPS guideline Competence Deceit Consent Debrief right to Withdraw Protection from harm Privacy |
| self report technique | open questions closed questions quantitative date qualitative data |
| interview types | structured un structured semi-structured |
| mistakes to avoid in making a questionnaire | jargon emotive language leading questions double barrelled questions double negatives personal questions near the begining |
| steps in questionnaire design | 1) aims and hypothesis 2) qualitative or quantitative date 3) pilot study to modify the questionnaire 4) sampling 5)ethical issues 6) data analysis |
| types of correlation | positive correlation negative correlation no correlation correlation is not causation |
| kinds of data | qualitative date quantitative data primary data secondary data |
| data analysis | central tendency- mean, median and mode the range standard deviation |
| types of data | discontinuous data- nominal, ordinal continuous data- interval/ratio |
| tables and graphs | results table bar chart histogram line graph scatter graph |
| distributions of data | normal distribution skewed distribution.- negative/positive skew. |
| peer review | researchers 1) perform research 2)write up in full detail 3) aim to get paper published peer review 1)validates 2) suggests improvements 3)allocate research funding |
| psychology application | learning approach behaviourism- treatment of phobias, animal training learning approach social learning- appropriate role models for children cognitive approach- improvements to education, computer modelling to artificial intelligence, create things such as lie detector tests biological approach- understand genetic basis of behaviour, evolution of behaviour, effects of hormones and develop drug theories |
| designing a research study AMVE SEMPA | Aims and hypothesis Method and design Variables Extraneous variables Sampling Ethics Materials Procedure and location Analyse and collect data |
| evaluating a research study GRAVE | genralisability reliability application validity ethics |
