In this part of the project, a study about the family shopping basket was done through statistics, where the eleventh-grade students proposed the exercise of comparing the prices of determined products, which were divided into four categories; proteins, grains, vegetables, and cleaning supplies, These products were compared between three renown supermarkets in Florencia, to find the establishment that benefits the economic aspect of the Florencian citizen, consider the variation of prices.  

In addition, this study has a great impact because it allows us to deepen our understanding of data organization with a statistical study method, learning to identify and create comparative charts and bar graphs. This is a big help in facilitating the organization and comparison of the prices of the different products. 

The aim of this project is to make a statistical study regarding the price of some products of daily use to compare and determine where people can find the most favorable prices. For this project we took into account three different supermarkets and selected four products of the same size and the same brand for each category to identify which one offers cheaper prices and quality. 

To organize the information, a general table was used which was divided into 3 parts to clasify the type of product and its price in the supermarkets, separating the total of the products in each one. In addition, bar diagrams were made in order to synthesize the information and generate a more accurate reading. All this to determine which 

supermarket offers better prices and quality to generate knowledge of statistics, citizens and also contribute to the social welfare and the economy of families.

In the protein category, Éxito is better with $41.610 compared to $46.240 for El Primo. In vegetables, the least expensive is Éxito with $3.170 and the most expensive is El Primo with $7.350, which means that it is more accessible to buy vegetables at Éxito.
