In any field of educational development, the data are very important to grasp a picture of that field. (What is important is not to depend too much on it since sometimes it won´t show what is actually going on in detail.)
The data can be used for daily life.
Recently, I am collecting data for something very important.
Project of Nutrition in Santiago (PNS)
-When: every weekend
-Where: La vega (market in Santiago de Chile)
-Activity: Collecting the data and buy fruits and vegetables
-Budget: 20,000 Chilean peso (approx. US 40$)
-General objective: Enjoy the life
-Specific objectives: Know the average price of the products/ buy high quality foods cheaply/ enjoy shopping
An example list is the following (by kilo/unit):
Brucella sprout 1000
Total 15100 (approx. US 30$)
