Companies have vast amounts of data, but it is rare to have someone with the ability to analyze that data to see trends and make predictions. Add a whole new skill set to your portfolio, and make a big difference in the success of your organization by acquiring data analysis skills. Begin with getting a basic understanding of how to analyze data in a business setting. Then learn how many of your business decisions involve comparing groups for differences. You will know the statistics behind these group differences and relationships. Finally you will find out how to perform inquiries that will be useful to your business or organization, and have the skill necessary to communicate these results through graphs and text that your fellow employees will understand. Whether your business is home based or a large company, this certificate will take you to the next level where important decision-making is concerned.
