What’s your knowledge of statistics and how have you used it in your work as a data analyst?

Data analysts should have basic statistics knowledge and experience. That means you should be comfortable with calculating mean, median and mode, as well as conducting significance testing. In addition, as a data analyst, you must be able to interpret the above in connection to the business. If a higher level of statistics is required, it will be listed in the job description.

Example
“In my line of work, I’ve used basic statistics – mostly calculated the mean and standard variances, as well as significance testing. The latter helped me determine the statistical significance of measurement differences between two populations for a project. I’ve also determined the relationship between 2 variables in a data set, working with correlation coefficients.”
