= Congratulations to all our potato competitors! =

Well done on a great Potato Olympics competition. Unfortunately, we had quite a few casualties and we will be holding a ceremonial burial in the vegetable garden on Monday. Also on Monday we will be doing a Skype link up with Mr Scanlon and his class at St. Aloysius Catholic College in Tasmania. You will be required to introduce yourselves, in your teams, to the students from the other school and explain what you learnt from this activity.

This week we will also start to use the data we have collected to learn more about summary statistics (mean, median, mode and range) and graphing (stem and leaf plots, scatter graphs and box and whisker plots).


 * Mean = average (add all scores and divide by the number of scores)

Median = middle value (put scores in order and find the middle value)

Mode = most frequent score

Range = difference between greatest and smallest value**

You will use the Google docs spreadsheets that have been created by St. Aloysius students to add our data and analyse the results. Is there a relationship between the vital statistics (height, girth, mass and volume) and the results of particular events?

For example, did the potatoes with the greatest volume make the biggest splashes? This prediction is called an '**hypothesis**' - a theory that you can use the data to find out whether it may be true or not.
