PI 2 (sleep and age)

Question 1

aim of your research

Answer 1

to find out if there is a difference in the quality of sleep between younger individuals and their older counterparts

Question 2

state and operationalise the variables you are assessing

Answer 2

IV Age of pps (in years)
DV sleep quality (scores on SQS test)

Question 3

age groups?

Answer 3

younger pps ages 10-20
older pps ages 45-55

Question 4

state an opperationalised experimental hypothesis

Answer 4

there will be a difference between the age of participants (in years) and the quality of their sleep (score on SQS)

Question 5

is the hypothesis directional or non-directional

Answer 5

non-directional

Question 6

why a non-directional hypothesis

Answer 6

because evidence shows their is a difference but the conflicting evidence available shows this could be either direction

Question 7

state a null hypothesis

Answer 7

there will be no difference between the age of participants and the quality of their sleep

Question 8

methodology?

Answer 8

quasi-experiment

(a research where the experimenter has not deliberately manipulated the IV and pps are not randomly allocated.)

Question 9

why a quasi-experiment

Answer 9

because age is naturally allocated condition and a correlation doesn’t give us a comparison

Question 10

experimental design?

Answer 10

independent groups

Question 11

why independent groups

Answer 11

it would be too difficult to match pps and the same pps cannot perform in both conditions as they either fit into the young or old category

Question 12

location of the research?

Answer 12

online

Question 13

why an online research?

Answer 13

we don’t have access to a sleep lab and the ecological validity will be higher doing it in the lab as their nights sleep will be more likely to reflect their usual sleep patterns
