Statistical Investigation

WALT: Carry out a statistical investigation.
For my maths investigation, I decided to ask Ruma J to estimate how many teddy bears were in the box. There were 29. 4 people guess that there were more than 35 teddy bears and 20 - 24 teddy bears. The least amount of estimates were in the 25-29 range, with only 3. I found it interesting that out of 16 people only 1 person guessed the right amount. The majority of people guessed in the 30-34 range. I would like to do another investigation on how many there are of each colour.
