Research Methods

Question 1

What is independent measures design

Answer 1

Where the sample takes part in one condition

Question 2

What is repeated measures?

Answer 2

Where the sample takes part in more than one condition

Question 3

What is match pairs design?

Answer 3

Where the sample is matched on sample characters and put into a specific condition depending on their group

Question 4

What is a self selected sample?

Answer 4

Where the target population reply to an advertisement

Question 5

What is random sampling?

Answer 5

Members of the target population are selected at random to gather the sample

Question 6

Strengths of random sampling?

Answer 6

• Everyone has an equal chance of being selected

* no experimenter bias

Question 7

What is an disadvantage of random sampling?

Answer 7

• may end up with a bias sample

* no control over the sample

Question 8

What is snowball sampling?

Answer 8

Where a member of your target population recruits people they know that fit the criteria for the experiment

Question 9

Advantage of snowball sampling?

Answer 9

•good at recruiting participants that may be hard to contact. Eg. Drug users that may not want to come forward voluntarily

Question 10

What is a Quasi experiment?

Answer 10

Where the groups are pre determined due to sample characteristics which can not be altered. Eg. Disabilities, age, gender

Question 11

What is a laboratory experiment?

Answer 11

The experiment takes place in an unnatural environment in which variables are controlled to alter the independent variable and influence the dependant variable

Question 12

What is a field experiment?

Answer 12

An experiment that takes place in the samples natural environment in which variables are at less control

Question 13

What is a self report method?

Answer 13

One which the samples fills out themselves, usually in the form of a questionnaire compiling of rating scales, open questions and closed questions

Question 14

What is an open question?

Answer 14

One that has the ability to be expanded on by the sample member, open to an extended answer with explanation and detail

Question 15

What is a closed question?

Answer 15

One with few answers, with short answers. Eg. Yes or no

Question 16

What is a positive correlation?

Answer 16

With an increase in the X axis there is a upwards correlationary increase along the Y axis

Question 17

What is a negative correlation?

Answer 17

With a increase in the X axis there is a downwards/decrease in the Y axis

Question 18

What is meant by ‘no correlation’?

Answer 18

There seems to be no connection between the variables

Question 19

Give an example of a null hypothesis for the effect of weather (hot or cold) on an individuals mood

Answer 19

There will be no change in mood of the sample when the weather is at hot or when it is at cold

Question 20

Give an example of a two-tailed hypothesis for the effect of puppy’s on the rating of happiness on a 1-10 rating scale (1 being sad and 10 being very happy)

Answer 20

Give an example of one tailed hypothesis on the effect of chocolate eaten on eye-sight when given an eye test

Answer 21

There will be higher scores on the eye-Sight test when given chocolate compared to the scores on the eye-Sight test when not given chocolate

Question 22

What is time sampling?

Answer 22

The experimenters note relevant behaviours at time intervals. Eg. Every five minutes

Question 23

What is event sampling?

Answer 23

The experimenters note relevant behaviours every time they appear

Question 24

What are coding frames?

Answer 24

The experimenters use a coding system to note behaviours. Eg. A tally

What is 1.4468 to 2 decimal places

Answer 25

1.44

Answer 28
