Statistics

13/06/2011. Kimberly where is your average person?? I can see that you have a few tables and one bar graph that is done incorrectly! You need to group your continuos data and then present it. You have got 32 different bars and this is why I taught you how to group it! You still have not told me who the average person in the class room is and I expect you to present this by Friday.

**Room 29’s eye colour raw data**

Jack.A = Blue Kata = Blue Kennedy = Blue/green Nicola = Blue Te Raina = Brown Shreya = Brown Kyle = Brown Jack.H = Hazel Vinu = Brown Sam = Hazel Karl = Blue/green Islah = Blue Kimberly = Brown Shavaugn = Blue Erica = Brown Bethany = Hazel Connor = Brown Toby = Brown Ethan = Blue Cody = Brown Jarrod.R = Brown Olivia = Blue Oliver = Blue Emily = Blue/green Taylor-Rose = Blue Madison = Brown Flynn = Hazel Samuel = Blue Jenna = Hazel Dylan = Hazel George = Brown Jarod.M = Brown

Reflection Tuesday 7th June: Today I put my information into a graph. As you may see Jenna has the biggest right handspan. Jack.H has the smallest right handspan.

Reflection Wednesday 1st June: I choose a green traffic light because I enjoy putting information into tally charts. I am learning about averages. Today I put my information into a tally chart and am hoping to find the range.

**FIND THE AVERAGE PERSON IN OUR CLASS**

LI - I am learning to use my statistic knowledge to find the average person in our class

SC - To be successful I will need to use some of the following:


 * tally chart
 * stem and leaf graph
 * bar graph
 * pie chart
 * pictogram
 * histogram
 * mean
 * median
 * mode
 * discrete data
 * continuous data
 * write 3 statements about each graph.

Your task is to find out who the average person in our is. You must **always** analyse your graphs and data, and make sure this analysis is evident.

To do this task you will be using **discrete data** and **only one continuous data.**

Below brainstorm as a group what discrete and continuous data you could use to help you find who the average person is in our class. Highlight all of your discrete data yellow, and continuous data green.

LI: We are learning to display our data as a bar graph.

SC: •use discrete data •labels and titles are used •has a Y and X axis •has numbers on the Y axis •bars are seperate •has statements about the data and results •everything needs to be the same distance apart e.g. numbers up the side, the bars, the labels

LI: We are learning to display our data as a pie chart.

SC: •the degrees have to be accurate. •use protractor or compass when drawing the circle •use titles and labels. •may have a key •must have a perfectly round circle •has statements about the data and results

Create a tally chart, bar chart and pictogram for the data given. Write three statements about each diagram. [|IXL Year 7 Interpreting/Creating Pictograms] [|IXL Year 7 Interpreting/Creating Bar Charts]
