scientist use observation and data by using common knowledge of all the things they already know , and by writing what the see down *Data* they can make an inference as to why something has happend
Theories
I am guessing from the sound of the question...
hypothesis
It is observation because observsation means what you see.
I suspect you mean the scientific method. Briefly outlined, the scientific method consists of the following tasks: Specify a testable null and an alternative hypothesis based on preliminary tests and observations. Design tests that will determine the validity of the null hypothesis to a specified degree of confidence. Collect data and observations for the tests according to requirements of tests and data sample spaces. Test the hypothesis using collected data and observations. Make conclusions and report on the validity (or not) of the hypothesis. Make recommendation for further studies or applications of the experimental results.

scientists test their hypothesis buy making observations or doing research

Data
A scientist may create an hypothesis on the basis of their observations. If their observations are carelessly made or recorded then any hypotheses they offer will be inaccurate reflections of nature. A scientist may alternatively collect observations to test an hypothesis. If these observations are carelessly made or recorded then the conclusions that the scientist makes about the hypothesis could very well be incorrect. At the very least the conclusions they draw would not be based on sound evidence (because the observations are unsound).
They use them to make new observations, that may result in the change of their theory.
Predict, test, observation, what acually happend
Grab a burger! xD. Make observations and test them out and then create a theory

gather information means to collect all information and put it in one
If you then test your theory - it is the Scientific Method.generalobservations
