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:

Unnecessary group (why is it unnecessary?): because it doesn't really matter to the question

Hard to interpret group  (why is it hard to interpret?): Because it doesn't make sense

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. Cats are the most liked

2.  guinea pigs are the least liked

3.  Dogs are 6 behind cats

Discuss with a classmate which graph (bar graph or pie graph) you would prefer to use to show the information and
why?

A bar graph because it has numbers and shapes that make it easier and exact

What is the mean of the data above? (Show your working)

12+6+8+4=30 divided by 4 = 7.5

Personal Reflection:

I find sorting data ….. rather easy because of all the numbers that make it easier
