GENDER DIFFERENCES IN MOBILE USE

Question 1

type of OBSERVATION

Answer 1

non-participant

Question 2

ALTERNATIVE HYPOTHESIS

Answer 2

there will be a significant difference in the number seconds male and female participants spend on their phone whilst on school transport

Question 3

NULL HYPOTHESIS

Answer 3

There will be no significant difference in the number seconds between male participants and female participants spend on their phone on school transport

Question 4

SAMPLING TECHNIQUE

Answer 4

opportunity sampling

each observer selected 3 pupils over the age of 16 to observe who attend this school and are travelling on the school train or bus either on the way to or from school

Question 5

PROCEDURE

Answer 5

1. Find a pp that fits the needed characteristics
2. Set a 3-minute timer on your phone
3. Start a stopwatch when they begin to use their phone, and stop when they stop
4. After the 3-minutes is up calculate how long they spent on their phone during those 3-minutes
5. Convert the time into seconds

Question 6

2 STRENGTHS of OPPORTUNITY SAMPLE

Answer 6

(+) opportunity sampling gives us a less biased set of data
(+) it was practical and safe

Question 7

a WEAKNESS of OPPORTUNITY SAMPLING

Answer 7

(-) due to using school transport we aren’t applying those who walk or a driven home- may produce biased results

Question 8

RESULTS of the DESCRIPTIVE STATISTICS:

Answer 8

mean: F= 135.3 M= 115.5

median: F= 145 M= 159

overall median= 151

low use= </151

high use= >/152

Question 9

OV and CV SCORES:

Answer 9

OV= 0.132
CV= 3.82

Chi-sqaured= OV>CV

Question 9

INFERENTIAL TEST used:

Answer 9

Chi squared test = nominal data was used with an independent groups design

Question 10

LEVEL of PROBABILITY used and why:

Answer 10

0.05- it’s a good compromise between type 1 and type 2 errors

Question 11

RETAIN or REJECT the NULL HYPOTHESIS:

Answer 11

retain

as the OV is less than the CV for a two-tailed hypothesis at a 5% level of probability the null hypothesis should be retained as the difference is not significant

Question 12

ETHICAL ISSUES and HOW they were DEALT with:

Answer 12

Right to Privacy- A busy train carriage is not one where there is any expectation of privacy

Confidentiality- no names or any personal data apart from sex were recorded
