AIMS
dfdf
1 of 29
what is an aim?
genera statement that describes purpose of investigation
2 of 29
so in the case of wondering whether theres something about driking energy drinks and talking it'd be like?
to inv wether drinking energy drinks makes people more talkative
3 of 29
HYPOTHESES
DFGDG
4 of 29
what is a hypothesis?
statement @ start of study that clearly states relationshiop between variables
5 of 29
so for this speedupp energy drink study?
drinking speedupp causese people to become more talkative
6 of 29
hypotheses can either be?
non/directional
7 of 29
what is directional hypothesis?
one that makes clear sort of difference anticipated
8 of 29
but non-directional?
simply states there will be a difference in conditions but not specified
9 of 29
DOING EXPERIMENT
DFGD
10 of 29
how u gonna operationalisel measure if it makes people more talkative?
see how many words they say in a 5min period
11 of 29
DECIDING WHICH HYPOTHESIS 2 USE
DD
12 of 29
when is it appropriate to use directional hypothesis?
when previous research suggests particular outcome
13 of 29
in which two instances would you use non-directional?
no previous research / previous research is contradictory
14 of 29
IN/DEPENDENT VARIABLES
DGDFG
15 of 29
which one does researcher manipulate?
iv
16 of 29
to record effect o change on?
dv
17 of 29
what about all other variables in proper experiment?
should be constant if could effect dv
18 of 29
why?
so researcher can be confident cause of effect on dv was iv alpone
19 of 29
LEVELS OF IV
DFGDF
20 of 29
in order to test iv wha tdo we need?
experimental conditions
21 of 29
could compare which two ways?
before / after drinking OR those that did and didn't drink it
22 of 29
in either case the two conditions are?
speedupp / no speedupp
23 of 29
these are two levels of iv claled?
controlled condition / experimental condition
24 of 29
well-written hypothesis should do what with these?
make clear what IV and DV are
25 of 29
why do variables have to be operationalised and what does int mean?
make hypothesis clear / testable
26 of 29
OPERATIONALISATION OF VARIABLES
GDDG
27 of 29
task for any researcher is to ensure variables being investigated are as what as possible?
unfuzzy / measurable
28 of 29
so what woudl be a good unfuzzy hypothesis about energy drinks?
After drinking 300ml of SpeedUpp pps will say more words in next 5mins than pps that drink 300ml water
