PLASTIC PERSUASION LEARNING OBJECTIVE: Use real life statistics as a persuasive device
THE DIRTY DOZEN Almost a decade ago, Surfers Against Sewage conducted a Plastic Pollution Brand Survey;a brand audit that revealed the majority of all beach litter (56%) was attributable to just twelve corporations, dubbed the ‘Dirty Dozen’. Talk in pairs, remember to prepare reasons for your answers. What might Surfers Against Sewage’s motive be for doing this survey? Can you suggest who the top culprits may be? How useful is this data now?
The Dirty Dozen Data Corporation In your pairs, choose three of the following questions to discuss. If the litter pick had been repeated the following week would the data be the same or different? Why? Is the data reliable? Why? What story does the data tell us? How can this data be updated? Approximately how many items of litter were collected in total? What is the range of this data set?
QUESTION:If the survery was repeated today would the Dirty Dozen remain the same?WHY?

Pictograms Pictograms use pictures to represent data. To make sense, a pictogram must always have a key. It is important to make sure that each picture is the same size, equally spaced out and lined up one beneath the other.
