<strong>Year</strong> 4—Sub-str<strong>and</strong>: Data <strong>representation</strong> <strong>and</strong> interpretation—DR&I – 1<br />

Select <strong>and</strong> trial methods for data collection, including survey questions <strong>and</strong> recording sheets<br />

(<strong>ACM</strong>SP095)<br />

Related Terms<br />

Teacher Information<br />

Data<br />

• A term used to describe a collection<br />

of numbers or information.<br />

Survey<br />

• To collect sample opinions or facts<br />

from a group.<br />

Table<br />

• A means of organising data in rows<br />

<strong>and</strong> columns.<br />

Tally marks<br />

• Marks made to record items or<br />

events, usually grouped in fives by a<br />

diagonal line (e.g. ).<br />

Venn diagram<br />

• A diagram that represents sets <strong>and</strong><br />

their relationships. The overlapping<br />

sections of the circles represent<br />

more than one choice.<br />

What this means<br />

• Students will be presented with a variety of methods they can<br />

use to survey <strong>and</strong> collect data. They will be given the opportunity<br />

to use different methods of recording data <strong>and</strong> evaluate how<br />

effective each one is. They will come to realise that when collecting<br />

data you need to decide what sort of information to collect, where<br />

<strong>and</strong> who to collect it from <strong>and</strong> how they will need to collect it.<br />

While some methods of collection suit some investigations, other<br />

surveys or data collection may require a different method. Through<br />

this learning process students will start to choose the most<br />

effective way to collect data according to the type of investigation<br />

they are doing.<br />

Teaching points<br />

• Demonstrate the importance of correct questioning when carrying<br />

out a survey.<br />

• Present students with a variety of methods for recording <strong>and</strong><br />

collecting data.<br />

• Encourage students to recognise that the type of data collection<br />

used depends on the type of survey or investigation.<br />

• Give students the opportunity to trial various data collection<br />

methods.<br />

• Allow students the opportunity to assess <strong>and</strong> evaluate the<br />

effectiveness of their data gathering.<br />

What to look for<br />

• Students who have difficulty choosing the most effective method<br />

to collect data for an investigation.<br />

• Students who have difficulty evaluating the effectiveness of data<br />

collection methods.<br />

<strong>Year</strong> 4—Sub-str<strong>and</strong>: Data <strong>representation</strong> <strong>and</strong> interpretation—DR&I – 1<br />

Survey topics (pg 77)<br />

H<strong>and</strong>s–on Activities<br />

• Present students with a list of possible topics that could be used in an investigation or survey.<br />

• Use the topics to initiate a discussion about necessary questions <strong>and</strong> how investigations can be carried out.<br />

• Ask pairs of students to choose a topic from the list (or their own topic) <strong>and</strong> to come up with a question <strong>and</strong> suggest a<br />

method for how they would go about finding out this information.<br />

Methods for collecting data<br />

• Brainstorm <strong>and</strong> list all the methods there are for collecting data. For example: a list, a table that uses tally marks, a table<br />

that uses ticks, a two-way table, a survey of questions, a Venn diagram, a number line.<br />

• Suggest examples of investigations you could carry out that would use each of the methods the students have<br />

suggested. For example: draw up a number line <strong>and</strong> write on one end the word ‘never’, the other end, ‘always’ <strong>and</strong> the<br />

word ‘sometimes’ in the middle. Ask students a question such as ‘Do you go to the beach on the weekend?’ Ask those<br />

students who never do to raise their h<strong>and</strong> then use ticks, dots or any mark to show these students above the word<br />

never. Then repeat the same method for ‘sometimes’ <strong>and</strong> ‘always’.<br />

Tables for data collection (pg 78)<br />

• Give each student a copy of the sample tables that can be used to collect data. What type of investigation could these<br />

tables be used for?<br />

• Ask students to write a question to find out what electronic equipment their classmates like to use the most. Which<br />

table would be best to use in this investigation? Ask students to choose one to use when surveying their classmates.<br />

• Once completed, ask students to compare methods of data collection. Which do they think was the best or easiest to<br />

use <strong>and</strong> read?<br />

Two-way tables (pg 79)<br />

• Two-way tables are a good method to show different opinions in a survey. For example, you could ask the question, ‘Do<br />

you like fruit, vegetables or both?’ <strong>and</strong> present this information in a two-way table. Look at the example of likes/dislikes<br />

fruit <strong>and</strong> likes/dislikes vegetables. Ask students questions about the table. Is the information clear?<br />

• Use the blank two-way table to survey 10 of your classmates if they like Xbox , PlayStation or both. Look at the results.<br />

Is this an effective way to present the information? Is there another way?<br />

Venn diagram (pg 80)<br />

• A Venn diagram can represent sets of information <strong>and</strong> relationships between<br />

these sets. The overlapping sections of the circles represent more than one<br />

choice. They are useful for showing information where those surveyed can<br />

choose more than one category.<br />

• Ask the class to raise their h<strong>and</strong> if they like Xbox , PlayStation , Wii , two of<br />

these or all three. Show their responses with a ✗ on a large Venn diagram.<br />

• Give the students a Venn diagram <strong>and</strong> ask them to survey 10 of their<br />

classmates to see if they like action movies, comedy movies or scary movies.<br />

Make a plan<br />

• Model to students how to make a plan for collecting data. For example, if you<br />

wanted to find out if you classmates prefer a party at home or at a venue, you<br />

would follow these steps:<br />

––<br />

Write a survey question.<br />

––<br />

Draw up a Venn diagram <strong>and</strong> survey your classmates as to their favourite type of party.<br />

––<br />

Ask each student in your class the survey question <strong>and</strong> record their response with a ✗ on the Venn diagram.<br />

––<br />

Total up the responses on the diagram.<br />

––<br />

Write one or two statements about the results.<br />

Links to Other Curriculum Areas<br />

English<br />

• Writing: In small groups brainstorm <strong>and</strong> make a list of students likes <strong>and</strong> dislikes. Discuss how these words are<br />

considered opposites e.g. if you were to say you like quiet music you may dislike loud music.<br />

• Writing: Create your own book of questions. They could be questions about life, questions you could use in a survey,<br />

questions you might use in an interview etc.<br />

• Spelling: Make a list of words that are opposite. For example: night—day, light—dark, heavy—light, tall—short.<br />

Information <strong>and</strong> Communication Technology<br />

• Demonstrate to students how to draw up a table in a word document. Tables are useful tools for collecting <strong>and</strong><br />

recording information. Before you create a table you need to work out how many rows <strong>and</strong> columns you need<br />

according to the number of categories you have in your survey.<br />

• Go to the website , click ‘Data’ then find ‘How to do a survey‘ <strong>and</strong> ‘Survey questions’. Read<br />

through both of these <strong>and</strong> compare their methods to what you know <strong>and</strong> have learnt.<br />

Science<br />

• Tables <strong>and</strong> diagrams are often used by scientists to show investigated information. For example: Investigate mini-beasts<br />

on the internet or use a resource book <strong>and</strong> then use a table such as the one below to show how many legs a variety of<br />

mini-beasts have.<br />

lizard<br />

beetle<br />

ant<br />

spider<br />

slater<br />

centipede<br />

f ly<br />

2 legs 4 legs 6 legs 8 legs<br />

• Use a Venn diagram to make a list of items in the classroom that are recyclable or non-recyclable.<br />

10 or<br />

more legs<br />
