Research Methods :Experimental Method

Question 1

theories are based on

Answer 1

understanding

Question 2

Where may we get our understanding from

Answer 2

newspapers,articles, research studies

Question 3

Aims are developed from

Answer 3

theories

Question 4

What are Aims

Answer 4

general statements
describe purpose of the investigation

Question 5

Give an example of an aim ( to investigate)

Answer 5

to investigate whether drinking energy drinks makes people more talkative

Question 6

what do we formulate after writing an aim

Answer 6

Hypothesis

Question 7

A hypothesis is

Answer 7

statement made @ the start of stuy

describes relationship between variables as stated by theory

Question 8

Give an example of a hypothesis

Answer 8

drinking coke causes people to become more talkative

Question 9

What are the two types of categories a hypothesis can be

Answer 9

directional
non directional

Question 10

What is a directional hypothesis

Answer 10

researcher makes clear

the difference anticipated

between two conditions/groups

Question 11

directional hypothesis includes words like

Answer 11

more /less
higher/ lower
faster/slower

Question 12

give an example of a directional hypothesis

Answer 12

people who drink coke are more chatty than those who don’t

Question 13

what is a non directional hypothesis

Answer 13

states difference between conditions

but the nature not specified

Question 14

give an example of a non directional hypothesis

Answer 14

people drink coke differ in terms of chattiness compared to who don’t

Question 15

what is the experimental method

Answer 15

manipulation of the IV to measure effect of DV

Question 16

What can be the different types of experiments

Answer 16

laboratory
field
natural
quasi

Question 17

when do you use a directional hypothesis

Answer 17

theory /findings of previous research studies suggest particular outcome

Question 18

when do you use a non directional hypothesis

Answer 18

when there’s no theory/previous research

or

findings from earlier studies are contradictorary

Question 19

the effects of caffeine are well documented therefore what type of hypothesis will we use

Answer 19

directional hypothesis

Question 20

When writing a hypothesis what do you have to check for

Answer 20

IV DV - clear & measurable

relationship between the IV and DV

right type of hypothesis

Question 21

What is the IV

Answer 21

Variable a researcher changes or manipulates

Question 22

What is the DV

Answer 22

variable you record and MEASURE the effect of

Question 23

Any effect of the DV is caused by ?

Answer 23

the change in the IV

Question 24

All other variables that may effect the DV should remain ?

Answer 24

constant/controlled in a properly run expermiment

Question 25

Why should variables, may affect the DV remain constant in a properlu run experiment

Answer 25

researcher confident change in the DV soley down to IV

Question 26

To test the effect of the IV what do we need

Answer 26

different experimental conditions

Question 27

if we just gave participants coke we wouldnt know... so we need a

Answer 27

how talkative they were comparison

Question 28

if we just gave participants coke we wouldnt know how talkative they were so we need a

Answer 28

comparison

Question 29

how would we be able to compare particpants chattiness 2 marks

Answer 29

copmare chattiness before and after drinking coke compare two groups of particpants - those who drank coke, and those who drank water

Question 30

in either case 2 conditions are either no coke or drinking coke these are what ...

Answer 30

the two levels of the IV

Question 31

What are the two levels of the IV

Answer 31

control condition : no coke /drink of water experimental condition : energy drink

Question 32

A well written hypothesis should make it well easy to

Answer 32

tell what the IV and DV are

Question 33

give an example of the directional hypothesis comparing two groups of participants

Answer 33

the group that drinks an energy drink will be chattier than those who drink water

Question 34

What is operationalisation

Answer 34

clearly defining variables in terms of how they can be measured

Question 35

why do we operationalise variables

Answer 35

to make it testable

Question 36

give an example of a good operationialised variable

Answer 36

after drinking 300 ml of coke , participants say more words in the next 5 minutes than particpants who drink 300 ml of water

Question 37

When our variables are operationalised we are free to concentrate on?

Answer 37

more important things
