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.
Level 4 Learning Outcomes:
- consider features of others’ statistical investigations including
appropriateness of sampling methods, quality
of data collection, data collection and the extent to which evidence supports claims.

READING OTHERS INVESTIGATIONS:
The information I have gathered from this graph is:
In 2000 the population of Emerald forest bears was pain staking low at only 40,000. Between 2001 and 2006 the community of the bears thrived up to 140,000. The difference is 100,000. I think that the bears grouping would have escalated because of the security of wild animals in the more modern day.
The information I have gathered from this graph is:
Clearly the graph states that cats are the most popular pet out of the survey.
34 people have been asked for their opinion on what pets they have.
I believe that the survey is a reasonable amount because 34 people is enough to certain a opinion.
Rabbits- 4
Hamster- 5
Goldfish- 6
Dog- 8
Cat- 11

The information I have gathered from this graph is:
Male listeners are more likely to buy a classical CD. Classical music is the most popular for the ages
45+. 16-24yrs is the least interested in this type of music. I believe that would be because at that
age they could be more interested in different genres; pop, rap.

The information I have gathered from this graph is:
It is certain that Coca Cola is a favourite with a large majority of 36%. Even though popular,
Sprite is the lowest outcome of only 10%. The difference is 26%. in between them is Diet Coke,
Pepsi Coke and Dr. Pepper. I would say that Coke classic has a majority because it is more
internationally well known.
