to use one or more of your senses to gather information

11

qualitative

words eg. colour

12

quantitate

numbers eg. measure

13

control group

group that serves the standards

14

experimental group

has manipulated variable

15

data

information

16

manipulated variable

the factor that is changed in the experimental group to make it different from the control

17

responding variable

the factor that is watched for during a controlled experiment

18

controlled experiment

a manipulataive experiment that compares 2 or more groups to test a hypothesis

19

observational study

a study in which the researcher carefully and systematically observes and records behavior without interfering with the behavior; it may involve either naturalistic or laboratory observation

20

epidemiological study

a study that involves large-scale comparisons among groups of people, usually contrasting a group known to have been exposed to some toxicant and a group that has not

21

independent variable

experimental variable

22

dependent variable

responding variable

23

Participants’ Rights

Ensuring that no psychological or physical harm is caused to the research participants and the researcher must also respect the participants’ rights as individuals.

24

Confidentiality


Participants have a right to privacy, so all details of their involvement in the study cannot be revealed in a manner that enables the individuals to be identified.

25

Voluntary Participation


The researcher must try to ensure that participants’ involvement in the research is voluntary. Participants must not be placed under any pressure to take part in the study.

26

Informed Consent


Participants must be appropriately informed of the nature and purpose of the investigation. Such informed consent must be documented and a consent form signed by the participant which is required before the experiment.

27

Withdrawal Rights

Withdrawal Rights
A participant must be permitted to withdraw from a study at any time, without giving a reason, should they wish to do so.

28

Deception in Research

Sometimes if the participants are told too much information about a study may influence their behaviour during the research and affect the accuracy of the results. When the researcher does not fully inform the participants of the study, they must ensure that the participants are not under too much distress from the procedure.

29

Debriefing

The researcher must provide an opportunity for participants to obtain appropriate information about the nature, results and conclusions of the research. Participants must be informed of the purpose of the investigation at the conclusion of the research. The researcher must correct any mistaken attitudes or beliefs that participants may have about the research.

30

Beneficence

The benefits of the study must outweigh the harm.

31

Limitation of experiment

- time (length of experiment)
- sample/population size (may/may not represent whole population)
Money

32

How to make fair test?

- same amount liquid etc
- environment
- same pop. size
- same people if possible

33

Graphing

- Independent x-axis (bottom)
- dependent y-axis (side)
- title
- labels

34

Controlled vs. experimental

The difference between a control group and an experimental group is one group is exposed to the conditions of the experiment and the other is not.
