You know what statistics is, right? Can you define "What is Statistics?" If you had to explain why statistics useful, and what statistics useful for, would you have an answer? Do you know how statistics makes a difference in all our lives, all the time? Describe how interpretation, translation, and communication of data into information aids in decision-making. Statistics is the science of learning from data, and of measuring, controlling and communicating uncertainty. Using Data to make informed predictable decisions. There is varibles that may or may not supercede the information. But the goal would be to make decisions based on factual data. Using data to make decisions based on interpretation of one's questions, what measurement can be controlled by the data. Lastly, demonstrating how the data is relative to the conclusion of the question.
