Abstract
The present article presents the results of a causal-comparative study, so we can determine the effectiveness of the campaign “Let’s Talk More Simple” in the level of banking of Arequipa. Information was obtained from three official sources: Association of Banks of Peru (ASBANC), National Institute of Statistics and Informatics (INEI) and Central Reserve Bank of Peru (BCRP), with which the ratios were developed to determine the level of banking in the city. We worked with a tab where we wrote down all the data collected from the sources mentioned above. Working with a significance level of 99% (p< 0.01), significant differences were found in the variations experienced by all the indicators found, except the credit cards of the PEA. All of that gives an account of the change in the level of banking in the city and the effect caused by the campaign “Let’s Talk More Simple”.
