Q

What was my one-tailed hypothesis for my experiment

A

Q

What were my controlled variables for my experiment

A

They both read the extract twice, all participants did the seven times table after reading the information, every participant did the seven times table for the same length of time, it’s the same information and it is the same song.

25
How many participants were there in my experiment
Six
26
What was the procedure of my experiment
One participant listen to some music which will be played whilst they read the extract twice. After they read it they will take the earphones out and recite the seven times table for one minute verbally. When the time is up they will then write down as much as they can remember from the extract. This procedure is exactly the same for the second participant, however they do not listen to the song whilst reading the extract.
27
What was the age range of the six participants within my experiment?
16 to 45
28
What were the results and conclusion of the experiment
The mean average of points without music was 14.6 in comparison to 11 with music. This concluded that my results prove my hypothesis.
29
What does my experiment make links to
The working memory model within the cognitive psychology section
30
What are the strengths of an experiment?
You can manipulate the IV It is controlled Procedure is standardised so results are reliable
31
What are the weaknesses of experiment?
Ecological validity is bad | Extraneous variables can occur due to pressure ect, leading to demand characteristics
32
What is the null hypothesis
Stating that there will be no relationship or difference between two variables
33
What is a one-tailed hypothesis
Predicting exactly what you think will happen in terms of the results so being able to predict the effects of the independent variable and the dependent variable
34
What is the two-tailed hypothesis
Predicting that there will be a relationship but you don't know what it is
35
What is a correlation
Shows the relationship between two variables
36
What two factors have to be in place to make a correlation?
The data has to be quantitive and continuous
37
What is continuous data?
Quantitive data with an infinite number of values for example ordinal data and interval data
38
What is ordinal data
It is a rating scale question so it is less precise for example how happy are you on a scale of 0 to 15
39
What is interval data
It's a very precise measure each point on the school has a fixed interval e.g. distances in centimetres
40
What is a positive correlation
As one variable increases the other variable increases however not necessarily at the same time
41
What is a negative correlation
As one variable increases the other variable decreases however not necessarily at the same rate
42
What are the strengths of a correlation
Because we have continuous data we can plot a scattergraph and see if there is a relationship You can tell how strong relationship is Spearman's Rho can measure the significance of the correlation It may be the only way to do a study in terms of ethics because you can give data that you couldn't physically do any experiment for example schmolk he couldn't physically give his participants brain damage
43
What are the weaknesses of correlational research
You can't be certain about cause and effect so that variable one is causing variable two or vice versa. Four example you can't be certain that the number of aggressive acts caused at break timecan be due to the number of hours of video games played (violent) as there could be other factors causing their aggressive behaviour There could be a third unmeasured variable that causes the relationship that is observed
44
What was my correlation study
How is drug crime in the UK changing over time
45
What was my hypothesis for my correlational research
My two-tailed hypothesis was that there will be a correlation between the amount of drug crimes in the UK and the number of years over time.
46
Where did we get our data from and what type of data is it for our correlation study
We use secondary data of reported police records
47
How did we do The study (correlation)
Took the secondary data and interpreted it into a correlation.
48
What were the results of our correlation study
Our results showed that from 2002 to 2003 until 2008 to 2009, there was a positive correlation however from 2008 2009 until 2013 to 2014, there was a negative correlation.
49
What was the conclusion of our correlation study
Spearmans rho told us that's the positive correlation was 1 and the negative correlation was -1 proving to be significant strong positive and negative correlations and therefore we are 99% certain that our results aren't due to chance. Meaning therefore that our 2 tailed hypothesis is correct.
50
What was our self report study
Which gender is more obedient
51
What is our hypothesis for the self report
It was two-tailed and state that there would be a difference between how obedient a person is and whether they are male or female
52
What sample did to use and how many participants were there (self report)
Opportunity sample | 13 females and 11 males
53
What was the age range of the participants and where did they come from (self report)
19 to 84 | Mainly the Midlands in the UK
54
What was the procedure for our self-report
Used the questionnaire to ask both quantitative and quantitative data , We then measured the quantitive data by points and adding them all together. 0 was least and 21 was most. We then calculated averages such as mean mode median and range of both the male and female results. After comparing the averages We then used standard deviation to see how read out the scores were and to see whether there was a trending score. To measure the qualitative data, we categorised it into themes.
55
What were the results of our self report study?
The quantitative data results showed that females are more obedience that males, however the females obedience scores are more spread out than males . Niamh calculated the Mann Whitney U and found that there was no more that a 5% possibility that chance caused the gender differences in the obedience scores. The qualitative data showed that people believe obedience is important, however it depends on the situation or the circumstance.
56
What are the strengths of a self report
You can collect both qualitative and quantitated data You can provide a brief and a debrief within the questionnaire You can categorise the qualitative data into themes You get their personal opinion
57
What are the weaknesses of self-report
The participants can interpret the aim of the study themselves creating extraneous variable and demand characteristics
58
What is subjective data
When the information comes from the participant themselves
59
Name the four different sampling methods
Random sampling, stratified, opportunity, volunteer
60
When can the findings from the study be generalised
When the entire group that is sampled is representative of the total target population, then it can be generalised to the whole population
61
Give 3 examples of extraneous variables
Demand characteristics - pp acts a certain way on purpose Participant variables - characteristics Situational variables - the environment affects behaviour
62
What is a situational variable
When the environment affects the behaviour/performance of the pp, eg. Fatigue or hunger or the temperature of the room
63
What is a confounding variable?
When the extraneous variables are not dealt with, so the variable actually affects the outcome of the study
64
What is a longitudinal study?
An experiment studied over a longer period of time
65
What are order effects?
If the participant is in more than one condition of the I.V. they may get bored - fatigue of Pp which means the results are less accurate - Repeated measures design & counterbalancing
66
What is counterbalancing
When in a RMD, the participants do both variables however in different orders eg. Participant 1 will do variable 2 and then variable 1, whereas participant 2 will do variable 1 and then variable 2. This counterbalances order effects as it balances out the results. For example if they did it in the same order, they would both be bored at the time of the same variable and therefore results wouldn't be as good.
67
What are the 3 types of experiment?
Quasi Field Laboratory
68
What is a quasi experiment
Naturally occurring I.V such as 'whether the pp is a girl or a boy'
69
What is a lab experiment?
Researcher manipulates the I.V
70
What is a field experiment?
Researcher manipulates the I.V in a naturalistic setting
71
What is an Independent Group Design?
Participants only do one condition of the I.V
72
What is a repeated measures design?
Participants to all conditions of the I.V
73
What is a matched participant design?
Pp are matched based on characteristics such as age and education
74
What are the 2 types of self report?
Questionnaire and interview
