Discussion
Data scientists exercise statistical thinking in designing data collection, derive insights from visualizing data, and gain supporting evidence for decision making. They also construct models for predicting future trends from data. Data scientists need to know statistics because statistics plays a central role in the data science approach.
With the plethora of statistical tests, researchers are sometimes faced with the difficulty of choosing the appropriate test under the ideal condition.
