types of experiment

Question 1

name 2 types of data in research

Answer 1

quantitative, qualitative

Question 2

define qualitative method

Answer 2

using data that is expressed in words and is non-numerical, qualitative data may be converted to numbers for the purpose of analysis

Question 3

define quantitative method

Answer 3

using data that can be counted, usually given as numbers

Question 4

name 3 common features of experiments

Answer 4

IV set up, DV measured, attempt to control EVS

Question 5

define laboratory experiment

Answer 5

an experiment that takes place in a controlled environment, the researcher deliberately changes the IV and measures the effect of the IV on the DV, it is easier to control EVS in a laboratory experiment than in a field experiment

Question 6

define field experiments

Answer 6

an experiment that takes place in a natural setting, the researcher deliberately changes the IV and measures the effect of the IV on the DV, it is more difficult to control EVS in a field experiment than in a laboratory experiment

Question 7

define natural experiment

Answer 7

an experiment where the IV is not changed by the experimenter but would have changed whether the experimenter was interested or not, the experimenter records the effect of the change on the DV. natural experiment can take place in real life (field) or in a laboratory

Question 8

name the strengths of lab experiments

Answer 8

EVS can be controlled which helps the experimenter establish a cause-effect relationship, can use standardised instructions because of level of control which controls EVS and the experiment can be repeated/replicated by another researcher if results same it confirms validity

Question 9

name the weaknesses of lab experiments

Answer 9

may not be like everyday life, behavior produced in labs may not generalise that well to the wider world, participants know they are being tested which may cause them to change their behavior which is not like everyday life causing low validity

Question 10

name the strengths of field experiments

Answer 10

often more realistic than lab experiments because they are conducted in a natural environment, participants dont know theyre being studied= behavior natural= good validity, follows standardised procedures = helps control some EVS

Question 11

name the weaknesses of field experiments

Answer 11

researcher may lose control EVS in RL setting= difficult to show cause&effect, ethical issues

Question 12

name the strengths of natural experiments

Answer 12

high validity cus they involve real life changes & these normally occur in a natural setting, when DV is measured in a lab there can be high level of control over EVS

Question 13

name the weaknesses of natural experiments

Answer 13

natural event that researcher is interested in may only happen rarely= fewer opportunities for this kind of research, because of unique characteristics of participants the researcher cant randomly allocate participants to the conditions of the IV which may act as an EV & affect the results

Question 14

define Validity

Answer 14

If the research tests what it claims to test ​

Question 15

define Ecological validity

Answer 15

If you can apply the findings of the experiment to real life settings ​
