- be aware of the type of data each display is appropriate for and the kind
of pattern/relationship it best communicates.
of pattern/relationship it best communicates.
- link others’ claims with the appropriateness of displays used.
WALT: Sort data into categories
Wiremu is allowed to choose a pet for his birthday.
He decides to find out what pets his classmates have.
He gives each classmate a blank data card, asks them to list any pets they have, and collects the cards.
With a classmate, discuss Wiremu’s data. Which information is necessary?
Which information is unnecessary? Which data is difficult to interpret?

Make a comment on one piece of data from above:
Unnecessary group (why is it unnecessary?):
I think that it is unnecessary because you can not really put thatstuff into a pet show.
Hard to interpret group (why is it hard to interpret?):
i think that it hard to interpret because it is hard to put that suff into a pet show.
WALT: Interpret and communicate findings about data
The class next door did a similar survey to the one above but they were asked to
name their favourite pet. The results are shown on this tally chart and then presented on the bar graph:
name their favourite pet. The results are shown on this tally chart and then presented on the bar graph:

2.it is most likely that people will bring a dog then a cat.
3.that guinea pigs are not very popular

Discuss with a classmate which graph (bar graph or pie graph)
you would prefer to use to show the information and why?
i most likely like the bar graph then all of the other ones because
they are way easier to read for me and my friends.

What is the mean of the data above? (Show your working)
i think that it means that all of the pets that they want bring was
put into a data graph to see what was most likely to come to
school on pet day.

Personal Reflection:
i think that i did great with my graph and that it is the besti have ever done in my math learning ever and i tryed
really hard to do this
I find sorting data …..
well i find sorting data hard but it is really fun to learn new things
like this so this was like an opportunity waiting to happen so i was
really happy when i we started to do this.

Lauren, you have shown you are able to sort out data provided and clearly able to interpret what is unnecessary/necessary data and explain why this is. Your next step is to look at the range, median, and mode of any data provided.
