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 />
