25
What is matched pairs?
Participants are paired together on relevant variables to the experiment. One participant form each pair is allocated to a different condition of the experiment.
26
What is counter balancing?
Controlling order effects in repeated measures. One group of participants are split in half, each participant does all conditions but half of the participants does condition A first then condition B vice versa.
27
What are lab experiments?
Takes place in a controlled environment. The researcher controls the IV and record the DV while maintaining the EV
28
What are strengths of lab experiments?
-Control of extraneous variables -Replications is more possible -internal validity high -DV most likely because of IV
29
What are the weakness of Lab experiments?
-Lack of generalisability -Lack of external validity( low mundane realism) -more chance of development of demand characteristics
30
What is a field experiment?
An experiment that takes place in a natural setting( tube) which the researcher can manipulate the IV and record the DV.
31
What are the advantages of field experiments?
-mundane realism -produces behaviour that is more valid -high external validity
32
What are the disadvantages of field experiments?
-no control of extraneous variables -ethical issues- no consent/privacy
33
What are natural experiments?
An experiment where the change in the IV is not brought by the researcher by would've happened even if the research was not there.- record effect of DV
34
What are the disadvantages of field experiments?
-These opportunities are rare -ethical issues -pre existing sample bias
35
What are the advantages of field experiments?
-Provides opportunities for research -High external validity
36

Researcher divide groups into sub groups based on characteristics that they share
44
What are the advantages of random sampling?
-Avoids bias from the researcher -Everyone is given an equal chance to be chosen -quick to organise
45
What are the disadvantages of random sampling?
-Not representative -difficult to gain access to to a large population
46
What does random allocation help with?
It helps with participant variables in an independent group design.
47
What are the advantages of Independent groups?
-Participants are less likely to guess the aim and less likely to produce demand characteristics. -Participants wont get fatigued by second condition.
48
What are the disadvantages of Independent groups?
-People are not the same( Iv might be affected because of participant variables than IV) -Less economical ( need two sets of people than just one)
49
What are the advantages of Repeated measures?
-Control of participant variables are you are comparing each person with themselves -One group (economical)
50
What are the disadvantages of Repeated measures?
-Order effects- repeating tasks might cause boredom -repeating skills might produce better performance in second task due to practice.
51
What are the advantages of Matched pairs?
-Participants only do one condition( no order effects or demand characteristics) -Matched on variables so participant variables are less of a problem.
52
What are disadvantages of Matched pairs?
-Participants are never matched exactly as they have individual differences. -Time consuming and expensive( if using personality test)
53
What are the advantages of opportunity sampling?
-Convenient and saves the researcher time, effort and money
54
What are the disadvantages of opportunity sampling?
-research bias -the participants may not take part -unrepresentative -willing and keep participants which will make it not generalised.
55

58
What are the disadvantages of volunteer sampling?
-May attract a certain type of person who is helpful, keep and curious which is less generalising -Unrepresentative as drawn from a specific area.
59
What are the advantages of stratified sampling?
-Free from researcher bias -accurate representation as it reflects the composition of the population.( generalisation is possible)

68
Define Consent Form/Letter
A document that includes all the relevant information that might affect their decision to participate.
69
What is Presumptive Consent?
Rather than getting consent from the sample, a similar group of people is asked if the study is acceptable or not. If agreed it is 'presumed' that the participants consent is given.
70
What is Prior General Consent?
Participants are given their consent to take part in a number of events and one which will involve deception. They are effectively consenting to being deceived.

When the individuals are likely to agree regardless of how they actully feel.
137
How is acquiscence bias defied?
Half the questions would be written in a negative way. If the participants would have looked at the question they would have opposite results.
138
What are the advantages of questionaires?(5)
-Cost effective -Can be completes without the researching being present -reduced effort for the researcher -easy to analyse -quantitative data lends itself to statistical anaylsis
139

A live entcounter where the interviewer askes a set of questions to assess an interviewees thoughts/experiances.
142
What is a structured interview?
A set of pre determined set of questions that are in a fixed order. (The interviewer askes the questions waits for a response and records the awnsers)
143
What is a unstructured interview?
No set of questions, just an aim or topic of what will be discussed.The interviewee is encouraged to expand and elaborate their awnsers.
144
What is the advantages of a structured interview
Straightforward to replicate and analyse due to their standardiesed format.
145
What are the disadvantages of an structured interview?

Analysis is dificult which makes it hard to draw conclusions. -Risk that interviewees lies due to social desirability.( can be over come buy building a rapport( a professional bond))
148
What can be used instead of a structured or unstructured interview?
Semi-Structured-A list of question that have been worked out in advanced and the interviewer is able to ask follow up questions.
149
What should you do when designing a interview?(7)
-An interview schedule -standardised -interview should toake notes or record the interview -1on 1 of in groups -quiet room from other peoples influnces -begin with neutral questions to make the particiapant more comfortable. -remind participants that their awnsers must be treated with confidence.
150

171
What are the measures of central tendancy?
mean, median and mode
172
How to measure mean?
Adding up all values in a set of data and dividing by the number of value there are.
173
What are the advantages of the mean?
-most representative as it includes all data.
174
What are the disadvantages of the mean?
Easily disorted by extreme values and can become unrepresentative.
175
How to calculate the median?
Arranging the values in a set of data from lowest to highest and picking the central value.
176
What is the advantages of the median?
-extreme scores do not affect it. -easy to calculate
177
What are the disadvantages of the median?
Less sensitive so not all scores are included.
178
How to calculate the mode?
The most frequent occuring value in a set of data.
179
What are the advantages of the mode?
Sometimes it is the only average available (eg with data in catagories)
180
What are the disadvantages of the mode?
Quite a crude measure, doesnt usually represent the whole data set.
181
What are the measures of dispersion?
The range and standard deviation.
182
How to calculate the range?
Subtract the lowest value from the highest value and add 1( as mathmatical correction).
183
What are the advantages of the range?
Easy to calculate.
184
What are the disadvantages of the range
-only takes into account the two extreme values so many not be representative of the whole data set.
185
How to calculate standard deviation?
Tells us how far scores deviate from the mean by calculating the difference between the mean and each score( dividing by # of scores)
186
What are the advantages of standard deviation?
Much more percise than the range as it includes all the values in the calculations.
187
What are the disadvantages of standard deviation?
It can be disorted by a single extreme value.
188
What is meta-analysis?
'research about research' Combining results from multiple studies to provide and overall view.

193
What data does scattergram/graph show?
-Used to display correlations
194
What is plotted on the x and y axis in a bar chart?
-catagories are plotted along the x axis -Frequency is plotted along y axis -the bars DONT touch
195
What is on the x and y axis in a scattergraph?
On the x axis one co variable on the y axis is the other co variable -needs 'relationship' in title
196
What data does line graphs show?

197
What are on x and y axis in a line graph?
Thr iv is plotted on the x axis and the Dv is plotted on the y axis
198
What data does histograms show?
Continuous data rather than discrete data(multiple levels of one catagory)
199
What do the x and y axis shows on a histogram?
-The x axis is made up of equal sized intervals of a single catagory -the y axis shows the frequency of each interval.
200
What is the shape of normal distribution graph?
When you measure certain variables, the frequency of these measurements should form a bell-shaped curve
201
Where is the median and mean and mode located in a normal distribution graph ?
They occupy the aame mid point of the curve.
202
Where are most people located on a normal distribution graph?
At the middle and very few people at the extreme ends.
203
What is a positive skew distribution?
Where most of the distribution is concentrated on the left of the graph resulting in a **long tail on the right**.
204
Where is the mode, mean, and median in a positive skew?
Mode: remains at the highests point of the peak median is next mean: is dragged across the right
205
What changes the values of the skew?
extreme values
206
What is a negative skew?
Where most of the distribution is concentrated towards the right of the graph, resulting in **a long tail on the left**.
207

210
What are the aims of peer review?
Before a piece of research can be published in an academic journal, it must go through a peer review. They will be scrutinised by 2/3 others in the field. To ensure that the research is of a high quality, contricubes to the field of research and is accurately presented.
