Q

what is the hypothesis

A

gender effects how much time sixth formers spend on mobile phones during breaktime
- there is no difference in the amount of time spent by male and female sixth formers on their mobile phones

Q

what was the methodology/design

A

there is no experimental design.
The observation will consist of 10 participants (first 5 males to walk in + first 5 females to walk in)
each will be assigned to a researcher - to record who will use their phones in the first mins/secs

Q

procedures

A

idea was put to an ethical committee
permission from head teacher + sixth former
presumptive consent obtained
1. 10 researchers sat in varying places
2. each person was debriefed
observing 1st male and first female

Q

event sampling

A

p’s were observed throughout the ‘event’ of breaktime
- so wont miss any phone acitivity
- just a snapshot

Q

sampling technique

A

opportunity sampling - first 5 males and 5 females to enter

14
Q

strengths and weakness of opportunity sampling

A
  1. convenience= participants from the target population are available and the researcher are able to observe but NOT REPRESENTATIVE
15
Q

descriptive statistics

A

ratio data was collected in form of time
to work out mean, median and mode of each group= to calculate range

16
Q

graphical representation

A

mean is in a table for comparison + pie chart to show division of use and non-use for males and females

17
Q

inferential statistics

A

independent groups design (males females)
and times spent on mobiles (ratio data)
Mann Whitney U test
for 2 tailed test with 10 p’s the critical value of u = 2
observed value is 6.2
higher than critical value

18
Q

accept null hypthesis ?

A

ACCEPT NULL
REJECT HYPOTHESIS
no difference in amount of time spent on males and female

19
Q

issues of validity

A
  1. operationalisation of mobile phones
  2. demand characteristics
  3. researcher bias
20
Q

why is timings/accuracy and issue
how was this controlled?

A

some researchers are more accurate than others
how was this controlled?
strict instructions were given all time

21
Q

why is individual differences and issue
how was this controlled?

A

may affect outcome if there is a reason such as uni offers / parent to call
make sample as large as possible for obersvation

22
Q

ethical issues

A
  1. lack of informed consent
  2. potential psychological harm
  3. confidentiality
  4. deception
  5. lack of right to withdraw
23
Q

issues of reliability

A
  1. time of day
  2. timings/accuracy
    3.individual differences of participants
24
Q

two ethical issues and how they were dealt with

A
  1. lack of informed consent- as participants were unaware they were being observed but this was dealt with being informed after observation during debriefing
  2. lack of privacy - as participants privacy was invaded, dealt with by observing participants in common room (public area) therefore no expectation of privacy
25
Q

issues of validity

A
  1. demand characteristics
  2. researcher bias
  3. operationalisation of mobile phone use
26
Q

operationisation of mobile phone use

A

just looking at time is superficial - no reasons why
dealt- content validity

27
Q

demand characteristics - IVal

A

p’s may spot the researchers watching them
dealt- be as inconspicuous as possible- blend in

28
Q

researcher bias IVal

A

may influence outcomes if we know who uses mobile alot
dealt- first 5 males and females to walk in
