Strand Sample Term 2

Strand Math Sample

Level 3 Learning Outcomes:

- gain information from a variety of data displays.

- be aware of the type of data each display is appropriate for and the kind 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:

a lot of people only have 1 cat.

Unnecessary group (why is it unnecessary?):

It is unnecessary for us to know if you don't have a pet and also a sister is not a pet!!

Hard to interpret group  (why is it hard to interpret?):

We don't know whether the cat in Australia is his or not.

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:

Write three statements that interpret the data shown above:

1.   More students like cats than dogs as there were 12 pupils compared to the 6 pupils who like dog

2. The mean is 7.5  

3.  Less people like Guinea Pigs than Horses

Discuss with a classmate which graph (bar graph or pie graph) you would prefer to use to show the information
and why? I prefer the bar graph as its easier to read and is clearer.

What is the mean of the data above? (Show your working)
12+6+8+4 = 30 divided by 4 = 7.5

Personal Reflection: I found this really easy and i would like to be challenged

I find sorting data ….. Quite easy because it is easy to understand and it is just placing things into groups.
