Pregunta
Aim: a general [blank_start]statement[blank_end] of what the researcher intends to investigate- the [blank_start]purpose[blank_end] of the study. Hypothesis: a [blank_start]testable[blank_end] statement that states the relationship between the [blank_start]variables[blank_end] being investigated.

Pregunta 2
Pregunta
A directional hypothesis: states what kind of difference there will be between the [blank_start]variables[blank_end]. They often include words like 'more' or 'less' e.g. People who drink caffeine will be more intelligent than people who don't. A non-directional hypothesis: simply states that there will be a difference, but not the [blank_start]type[blank_end] e.g. People who drink more caffeine will differ in terms of intelligence when compared to people who don't drink caffeine.

Pregunta 3
Pregunta
Researchers usually use directional hypotheses when previous research suggests no particular outcome. When previous research suggests a particular outcome, they'd use a non-directional hypothesis.
Respuesta
- True
- False
Pregunta 4
Pregunta
In an experiment, the researcher manipulates the [blank_start]independent[blank_end] variable and records the effect of this change on the [blank_start]dependent[blank_end] variable.
Respuesta
-
independent
-
dependent
Pregunta 5
Pregunta
Levels of the IV: the [blank_start]control[blank_end] condition (e.g. No caffeine/ drink of water), the [blank_start]experimental[blank_end] condition (caffeine). An effective directional hypothesis should distinguish between the IV and DV e.g. The group who drink caffeine will be more intelligent than the group who drink water. The only issue with this hypothesis is that it doesn't include the [blank_start]operationalisation[blank_end] of the variables (explained in other question)
Respuesta
-
control
-
experimental
-
operationalisation
Pregunta 6
Pregunta
Operationalisation of variables includes ensuring the variables being investigated are [blank_start]measurable[blank_end] and therefore unfuzzy, e.g. Participants who drink 200ml of coffee in one hour can answer 5 more questions in a 20 minute period than participants who drink 200ml of water in one hour.
Respuesta
-
measurable
-
immeasurable
-
subjective
-
confounding
Pregunta 7
Pregunta
Extraneous variables: any variable other than the [blank_start]IV[blank_end] which may have an effect on the [blank_start]DV[blank_end]. They [blank_start]do not vary[blank_end] systematically with the IV. Confounding variables: any variable other than the [blank_start]IV[blank_end] which may have affected the [blank_start]DV[blank_end] so we are unsure of the true source of the changes to the DV. They [blank_start]vary[blank_end] systematically with the IV.

Pregunta
Demand characteristics: in which the participant guesses the [blank_start]aim[blank_end] of a study, and then acts accordingly e.g. As they believe they are [blank_start]expected[blank_end] to behave, or try to over-perform to [blank_start]please[blank_end] the researcher.

Pregunta 9
Pregunta
Investigator effects: how the [blank_start]researcher[blank_end]'s behaviour influences a participant's behaviour e.g. Smiling at certain participants but not others. It can also refer to the [blank_start]actions[blank_end] of the researcher related to the study design e.g. Selection of participants, the materials, the instructions etc. [blank_start]Leading[blank_end] questions are also an example of investigator effects

Pregunta
[blank_start]Randomisation[blank_end] refers to the use of [blank_start]chance[blank_end] wherever possible during an experiment to reduce investigator effects.

Pregunta 13
Pregunta
Experimental Design: 1. [blank_start]Independent[blank_end] groups: [blank_start]two[blank_end] separate groups, one group does control condition, other does experimental condition. Results are compared. 2. [blank_start]Repeated[blank_end] measures: [blank_start]one group[blank_end], does both the control condition and the experimental condition. Results are compared. 3. Matched pairs: choosing one group, then choosing another to [blank_start]match[blank_end] participants in the first group (e.g. Based on IQ, culture etc.) One group does control condition, other does experimental condition. Results are compared.

Naturalistic observations have high [blank_start]external[blank_end] validity as findings [blank_start]can[blank_end] be generalised to everyday life.

Controlled observations [blank_start]can't[blank_end] be easily generalised, but extraneous variables are [blank_start]less[blank_end] common so replication is [blank_start]easier[blank_end]
