You will be coming up with a survey in groups which will be distributed to other students or teachers at Nations. You will then need to organise the results, and present them clearly with some conclusions. Task One: Preparing a Survey
Each group will produce a survey - a draft on paper first, then a good copy using Google Forms. You need to decide on a topic or theme for your survey as well as the sample you intend to survey (ie. who you intend to survey). The survey you create should be easy and quick for someone to fill in. You can choose a topic of your choice. Your survey should have 4 questions. None of your questions should result in continuous data. You will do this in year 8. You must design your survey so that you have the following criteria (Your teacher will help explain this to you) Two questions that result in categorical data (words) that you can organise into a tally/frequency table and then display in a pictogram, pie chart, a bar chart, a comparative bar chart or a compound bar chart. Make sure you include the categories (answers). Example: How do you get to school? One question that results in discrete numerical data (whole numbers) which produces a low number of possible answers and that you can organise into a frequency table. Example: How many TV’s are in your home? One question that results in discrete numerical data (whole numbers) that produces a high range of possible answers and that you can organise into a grouped frequency table so you can then find the modal class. Example: How many songs do you have on your ipod? Task Two: Organising and displaying data
Once you have collected your data, you will then need to clearly organise it into tables and graphs. Each member in your group will be responsible for one question. For your question, you must a) prepare a frequency table OR a grouped frequency table b) prepare one of the following graphs by hand – pick a different graph each: a pictogram a bar chart a combined bar chart a pie chart Your group will arrange the following items on a on a poster: a title indicating the topic or theme of your survey a copy of your survey – include a statement about who you sampled (ie. Yr 7, teachers, etc.) the 4 frequency tables and graphs with the name of the person who prepared them Task Three: Presentation - Tuesday 16th December Your group will present the poster to the rest of the class by describing the survey and sample and by having each member briefly discuss their graph and at least one result/conclusion you can make based on the graph. Group 1: Cillian, Daniel S, Liv, UtsavGroup 2: Aditya, Augusta, Liam, LizzieGroup 3: Ayann, Camille, Joonas, SeanGroup 4: Federica, Dan W, Leo, PeterGroup 5: Elie, Farah, Octavia, Pax __________________________________________Task 1: Preparing a Survey__________________________________________Task 2: Organising and Displaying DataFrequency Table / Grouped Frequency Table

1. Describe any restrictions on the questions you were asked to create. Hints: you could discuss the number of questions you were allowed to have in your survey types of questions you were permitted to ask 2. Describe why you chose your questions in helping you with your chosen topic. Hints: you could discuss the type of data you wanted to collect and how the questions you chose helps achieve the type of question you chose on Google Form and why. who you wanted to have as your sample/population and how this related to your chosen how these things help create a good survey that would generate the results you wanted 3. Did the data or results your group collected made sense? Hints: you could identify examples of where the data or result made sense. Explain why. identify examples of where the data or result did not make sense. Explain why not. 4. Do you think the conclusions you could make based on your results would be accurate? Hints: you could identify which conclusions you think would be accurate. Explain why. identify which conclusions you think would be not accurate. Explain why. think about whether your conclusions based on your sample could be applied accurately to the population. Edit Year 7 Exercises HERE |
