At the minimum, data analysts should have knowledge and experience using basic statistics, including mean, median, and mode, and be able to conduct significance testing. A more advanced level of statistics may be required, but this would be specified in the job description. Data analysts should not only know how to calculate these basic statistics but should also be able to interpret them about the business. The interviewer will ask your question to confirm all of this and determine your level of expertise.

"I use statistics on a regular basis 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 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.
