Part A- Designing and Collecting Data

Task 1:

A) The population currently at Narangba Valley State High School is 1232. There are 440 year 10’s, 437 year 11’s and 355 year 12’s.

B) The sampling method used for collecting my data was a 10 question survey, which I gave to 7 year 10 and 11 students and 6 random year 12 students. These students were randomly selected.

C)

I chose to randomly survey 7 year 10’s and 7 year 11’s because from the above equations the results are closet to 7 students for both year 10 and 11 therefore making the survey results more accurate. I chose to randomly survey 6 year 12’s because also from the above equation 6 students from year 12 should be surveyed from the whole population of year 12. I also chose to survey 20 people all together because 20 is less than 1% of the population therefore getting only a small selection of answers.

Task 2:

1) Do you have a job? Yes/No

2) On average, how many hours do you work per week? _____________

3) What are you average grades (only one answer)? _________

4) How many hours a week do you study? __________

5) How many shifts do you have per week? _________

6) Do you agree or disagree that having a part-time job is disruptive while completing school? A) strongly agree B) strongly disagree

7) Do you do any extra-curricular activities outside of school? Yes/No

8) A) if yes, for how many times per week? _______ B) if no, how does this help you with your school work? i)more study time ii) more focused iii)more time for improvement on assignments

9) How much time per week does your extra-curricular activity take up? _________

10) Does the extra-curricular activities impact your grades? A) no B) partially C) yes

Task 3:

A) Categorical: Q1, Q3, Q7

B) Ordinal: Q6, Q10, Q8b

C) Discrete: Q2, Q5, Q8a, Q9

D) Continuous: Q4

Categorical: These questions fit into this category because they all have no particular order because the data values are just names.

Ordinal: These questions fit into this category because the data has no order, but the difference between steps are not meaningful.

Discrete: These questions fit into this category because the data has only certain values

Continuous: These questions fit into this category because the data can have any value, although here may be a max and/or min.
