Problem solving is an important skill that every data specialist needs to possess. About 90% of the workload of a data specialist  requires critical thinking and the ingenuity to ask questions.

For example, if the sales rate of the blue bicycles in a business's outlet is so low, a data specialist needs to analyze where the root cause comes from? Is it because other colors are preferred? Or the blue bikes have a higher price than others?

A data specialist must ask the right questions, use his logical thinking ability to read and understand information, and come up with a plan to deal with challenges, overcome weaknesses and promote strengths. The more sensitive they are to the figures, the faster they will find a reasonable and effective solution.

3. Mathematics skills
