Stem and leaf graph.

WALT: To draw a Stem and Leaf graph.

During maths we have been learning how to draw a Stem and Leaf graph. This is a reflection that I have used to show my learning. I have made this by doing a Reaction test with my learning partner Maia. What you needed was a ruler a pen/pencil and a book to write your data in. First you measure the distance between your partner's hands to 20cm, then you have to hold the ruler in between your partners eyes. Next without telling them when, you drop the ruler and see when they try to catch. Lastley you see what the distance between the 10cm and the number before your thumb. Do this ten times before you make your Stem & Leaf graph, recording the ten numbers from each time you do this. The 30+ is for when you don't manage to catch the ruler.

Statistics:  Stem and Leaf Graph

WALT: gather, display and discuss data

Success Criteria:  

• Gather relevant information
• Display data on a stem and leaf graph
• Make some conclusions about the data

Task:

To present information about reaction times using a ruler.

Data:  30+, 22, 29, 29, 30+, 17, 30+, 21, 30+.

Stem and Leaf Graph:

Sorted Stem and Leaf Graph:

Conclusions: The most common score was 30+ beating 29 by one try.
The least common was the teens with only one number.
The worst result was the number 29 if you don't count 30+.
The best result was the number 17.

Assessment:

Self Assessment:

• I can gather relevant information

• I can display data on a stem and leaf graph

• I can make some conclusions about the data

Peer Assessment:

• I can gather relevant information

• I can display data on a stem and leaf graph

• I can make some conclusions about the data

I think I achieved the succcess critearia because I can: 

• I can gather relevant information

• I can display data on a stem and leaf graph

• I can make some conclusions about the data
  and I have showed this in my work.
