CLASS AVERAGE DATA: HOW MUCH WASTE DO THE CLASS PRODUCE?

Here you have a graphic showing the class average data. I did the graphic using the following table:

We have 9 columns, one for each student who gave me the data. The right column called media (average) is the sum of all the numbers in that line and then divided into 9. The units are grams.
After that I have calculated the percentages of each kind of waste (plastic, glass, paper, and so on) and put them in a graph

As people can see in the graph, over 50% of the waste produced by the students' families was organic.The organic waste is the most abundant kind of waste followed by the plastic waste.

COLLECTION CENTER

• Old televisions have to be thrown in a collection center.
• We always have to throw fluorescent tubes to a collection center because they contain dangerous gases
  
• Mobile phones can be recycled if we take them to a collection center.
• Furniture must be thrown in a collection center.
• We have to throw our old car batteries to the collection center.
• We have to bring our old computers to a collection center in order to recycle them.
