Collecting data

Many times scientists have an idea of what the outcome will be, or a hypothesis.  In the scientific method, experimental studies can test predictions for accuracy.  In the design of the experiment, there must be a repeatable factor so other researchers can reproduce the results.  There must be statistical measures of the reliability.  Collecting and manipulating data requires different mathematical tools that make the interpretation of the results easier.  Math tools such as graphs help to determine the results.

Sometimes the hypothesis is wrong.  This is referred to a null hypothesis.  Scientists can use a wrong answer to eliminate possible solutions, helping to find the right answer.  Either something was wrong with the design of the experiment or the answer was not an option for that experiment.  This is information that a scientist can build on.
