Talk about your knowledge of statistics and how you used this knowledge in your analytical projects.

"I use statistics regularly as a data analyst. For the majority of my work, I calculate basic statistics such as the mean and standard variances. I also conduct significance testing frequently to determine if measurement differences between two populations are statistically significant and worth highlighting for further investigation. In addition, for a few projects, I have worked with correlation coefficients to determine the relationship between two variables in a data set."

You may be tempted to provide the Morningstar interviewer with a great deal of information about your ability to use statistics. This may result in a long, drawn-out answer. Try to avoid this. When you are asked about your capabilities, keep your answers brief and to the point. The interviewer will use follow-up questions to explore this topic in more detail if they want to.
