Statistics

17/06/11. Great job Emily fantastic to see that you have now applied your knowledge to help you find out who the average person in room 29 is!

**The average person in the class is.... Cody Jefferson who has brown eyes,his favourite animal is a dog,his favourite sport was other,his hair colour is brown and his favourite colour was other. Those are all the top voted things for the four things I did.** z **The Mean,Median and Mean**

**Median:** For eye colours Hazel is the middle colour.For favourite animals it is 12 for the middle animal.For favourite sport it was Other as the middle vote.For hair colour brown was the middle colour and for favourite colours the middle number was red.

**Mode:** Brown (for eye colour),dog (favourite animal),rugby (favourite sport),brown (hair colour) and other (favourite colour) where all the most frequent.

**Mean:** I did discrete data so I therefor could not do a mean.

Today worked more on the average in the class and wrote down the favourite animals and coulors

Today I learnt what the range is and what you can do with it.Also why you use the range

__ 12.05.2011 __

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

**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
