AIMS AND HYPOTHESIS

Question 1

Aim

Answer 1

an aim is a generally phrased statement intending what the researcher wants to invest

Question 2

hypothesis

Answer 2

hypothesis is a prediction to the investigations outcome which makes a specific reference to independent and dependent variables.

Question 3

operationalisation

Answer 3

carefully stated demonstrating how exactly they are to be measured example reaction time in miliseconds,

Question 4

types of hypothesis

Answer 4

null and alternate hypothesis
alternate hypothesis further divided into one tailed or two tailed hypothesis

Question 5

directional or one tailed hypothesis

Answer 5

states there is a difference in measurement of dependent variable as a result of manipulating the iv, and says the direction where the results would go.

Question 6

non directional or two tailed hypothesis

Answer 6

states there is a difference in measurement of dependent variable as a result of manipulating iv, but doesnt say the direction where the results would go.

Question 7

example of non directional hypothesis

Answer 7

there is a difference in number of words recalled by participants in green light as compared to participants recalling in blue light.

Question 8

example of directional hypothesis

Answer 8

there is an increase in number of words recalled by participants recalling in green light as compared to participants recalling in blue light.

Question 9

falisifiability

Answer 9

even a well established theory needs to be accessible to the possibility that new research will emerge which will contradict its basic principles.
the more a research is able to withstand the attempts to falsify it, the more confidence we tend to have in that research

Question 10

demand characteristics

Answer 10

any cue the researcher or research situation may give which make the participants likely to be able to guess the aim of the investigation.

Question 11

please u effect

Answer 11

participants may act in a way the researcher wants rhem to act

Question 12

screw u effect

Answer 12

participants may intentionally underperform to sabotage the studys results.

Question 13

investigator effects

Answer 13

where a researcher consciously or unconsciously acts in a way to support the particpants predictions.

Question 14

randomisation

Answer 14

randomisation is use of chance to reduce the effects of bias from investigator effects.

Question 15

standardisation

Answer 15

using the exact same formal procedures and instructions for every single participants involved in the research.
