Deception- ps should not have information withheld from them or falsely ive to them

Consent- ps should be informed about the research and ive their permission to participate in it

Confidentiality-information about the ps have to be treated confidentially

Observation- when observing covertly, it should be done only in public place

anakarlacr2009 — 2025-10-02 19:15:58 UTC

Withdrawal- ps should be allowed to drop out the study at any time

Protection- ps should be protected from psychological and physical harm

Advice- ps should be offered advice if needed during or after a study.

Debrief- ps should be always have a debrief after the study to undersantd the full research aim. Advice and a way to contact the research might be here.

Types of design

anakarlacr2009 — 2025-10-02 19:26:55 UTC

Independent measures- ps only take part in one condition of the experiment

Repeated measures- ps take part in both conditions of the experiment

Matched pairs- pairs participants with similar characteristics complete just one condition each to control individual differences

Research method

anakarlacr2009 — 2025-10-02 19:39:58 UTC

Quasi- the IV is naturally occuring

Field- the IV is manipulated but the study is conducted in a natural environment

Lab- the environment is controlled and the IV is manipulated

IV- independent variable

anakarlacr2009 — 2025-10-02 19:44:55 UTC

what the researcher changes in order to see an effect on someting that they are measuring

DV- dependent variable

anakarlacr2009 — 2025-10-02 19:46:12 UTC

the variable that the researcher measure with the IV's.

anakarlacr2009 — 2025-10-02 19:53:24 UTC

Extraneous variables- a variable other than the IV that could affect the Dv and needs to ne controlled.

Confunding variable- a variable other than the IV wich has actually directly affected the Dv by mistake

Alternate hypothesis

anakarlacr2009 — 2025-10-02 19:58:18 UTC

There will be a significant difference in (Dv) of participants when (C1) is compared to (C2).

NULL

There will be no significant difference in (Dv) of participants when (C1) is compared to (C2).

se lembrar de dar contexto máximo sempre. Tempo do estudo, local, nome

Two/one tailed

anakarlacr2009 — 2025-10-02 20:03:35 UTC

Two tailed é confuso, não se sabe exatamente do que se trata.

One tailed é mais específico.

One tailed- The (DV) will be a significantly xxxxxx in (C1) when compared to (C2).

xxxxx- higher, more, lower, longer, more effective- O QUE DE DIFERENTE

IM-

Strength- no chance of order effect

less chance of PS working out the aim and changing their behaviour

Weakness- more PS, individual differences

RM-

Strength- no individual differences

fewer PS may be needed

Weakness- risk of order effects more chance of demand characteristics

MP-

Strength- no order effects

individual differences are reduced

less chance of demand characteristics

Weakness- less chance of demand characteristics, researcher may need more PS

less chance of demand characteristics

Laboratory (Lab)

Strengths:

High control; Easy to replicate;

Clear and easy to manipulate

Weaknesses:

Low Ecological Validity; High risk of Demand Characteristics

Field

Strengths:

High Ecological Validity; less Demand Characteristics

Weaknesses:

Less control over extraneous variables; more difficult to replicate; time-consuming and expensive.

Quasi-

Strengths:

Allows researchers to study IVs that can't be manipulated; Higher Ecological Validity than a Lab experiment

Weaknesses:

Pre-existing Participant Variables act as confounding factors; it's difficult to establish a definitive cause-and-effect.
