Whilst relevant published and unpublished literature provided the secondary data. The total number of questionnaires distributed was 286, out of which 260 were returned. Descriptive and inferential statistics were used for the data analysis. The statistical tools used include frequency table, multiple regression analysis, analysis of variance, correlation analysis. The results showed that there was a significant relationship between the ethical practices of organizations and their corporate performance.
