Student Survey

Introduction

Having learnt all the statistical techniques in the previous lessons, it's time to apply them to investigate questions about your peers that you are interested in.  For example, how do they get to school?  How many siblings do they have?  What is their favourite subject?

In groups, you are to:

1. Design a questionnaire (Google Form) to collect all the data you need.

1. • You will send this out to the whole class and answer each other's questions.

   • Make sure the questions have a mix of type of answer, e.g. words, multiple choice, a 5-point scale, numbers.

   • Here is an example of a questionnaire.  Be creative!

2. Produce a report (3-4 pages maximum) about the question(s) you want to investigate, your report should include the following things:

   • Heading: (Write a short statement of what this investigation is) 

   • Introduction: (Write a paragraph to describe briefly what the data is about) What will you compare? What will you do to collect the data? How would you record the data? How would you present the data? What calculations will you do?

   • Hypothesis: (Write a short statement to predict what you think will happen)

   • Result table: (This table summarizes the data collected)

   • Discussion: (Comment on the results. You can comment on the results e.g. how do boys and girls compare, and then comment on how do the first attempt and the second attempt compare)

   • Graphs:  (Download and insert appropriate graphs here, the graphs should have a title and axes labelled)

   • Discussion: (Comment briefly on your graph e.g. which score has the highest frequency)

   • Conclusion: (Write a paragraph to summarize your findings)

Some important notes:

• You are expected to use technology to draw graphs and perform calculations but make sure that the report includes relevant information to show that you understand what you have done. So for calculating the mean you should show the division of the total by the number of pieces of data, and for the range you should show the subtraction of the largest value by the smallest value. Do not just write down the answer.

• If you use technology to draw graphs then you should check that the graph has appropriate scales and labels/titles, and that the colour scheme you have used helps to communicate the information that is shown in the graph. Each graph and calculation should be followed by a comment saying what it tells you.

If you are stuck for ideas, you may wish to use the following ideas as a starter.  The different parts of the task are designed to get harder, so Task 1 should be the easiest and Task 4 the most difficult.

Task 1 – Sports

•  Create a frequency table for favourite sports.

•  Draw a graph to show which sport is the most popular.

•  Comment on what your graph tells you.

•  Create a frequency table showing the favourite sports for students in your house (Da Vinci, Einstein, etc).

•  Show these results on a graph.

•  What differences are there between the results for your own house and those for the whole year group?

Task 2 – Favourite Subjects

•  Create a frequency table to show which school subjects the students said were their favourites.

•  Draw a graph of this data and make a comment about favourite subjects.

•  Do the same for least favourite subjects (a frequency table and a graph).

•  Compare favourite subjects for girls with those for boys. Are there differences between which subjects girls like and those which boys like?

•  For each subject calculate a “net preference” score, that is the difference between how many people say it’s their favourite and how many say it’s their least favourite.

•  Graph your “net preference” results and comment on what your graph shows.

Task 3 – Siblings

•  Calculate the mean, median, mode and range of the number of siblings for Year 7 students.

•  Which is the best average to use and why do you think that?

•  Draw a graph to show how many people have 0, 1, 2, 3, 4 or 5 siblings

•  What is the average number of siblings for people living on Hong Kong Island?

•  What about for people living in other districts?

•  Draw a graph to show the average number of siblings for each of the four different HK districts. It is your choice of which average (mean, mode or median) to use.

•  “People from larger families will live further away from school.” Do you think this statement is true?

• Use statistics you have calculated to justify your answer.

Task 4 – Hours on Social Media

•  “Girls spend more time on social media that boys do”.

•  Do you agree with that statement?

•  Use the data in the spreadsheet to help you answer the question.

•  The answer isn’t just your opinion. It must be supported by evidence from the survey.
