data collection
It is important to plan experiments because if you don't know what you are going to do, and you get something wrong, then you wont know how to correct the procedure so it will work. If you plan an experiment, then you can always go back and read it.
Not always really... First it depends on the type of knowledge you're looking for. If it is general knowledge, it can be gained from life experiences , problems, questions, university, friends... And if it is scientific knowledge, then it may depend on scientific experiments, according to the subject you're managing.
Your question is incredibly ambiguous. In general, scientific technique probably refers to the scientific method, which is always used with somewhat little variation.-Find a problem or question of why something happens-Hypothesize the mechanism of why it happens the way it does.-Make predictions of what the hypothesis implies (guess the outcome of experiments)-Conduct experiments based on your hypothesis to see if they match your predictions-Analyze the results and data from your experiment.It may be necessary to repeat the process. And remember, negative results (when your predictions are wrong) are still results--they show you what not to do, and how something ISN'T, which is very important in making progress.

It is fair to say that the scientific method is always intended to produce better theories.

they are able to cut things in half if 2 experiments are being worked together they always have a different way of doing things
A constant is a variable that always stays the same, e.g. A factor in a controlled experiment that doesn't change.
Some very important scientific attitudes include consistency in specimen collection and collection of inferences. When doing a test, it is always good to record some prevailing conditions so that they can be replicated when conducting another similar test.
Although some marketers do consider marketing a science, it is really more of an art. This is because marketing results can't always be replicated the way that scientific experiments are.

Today the field of science is expanding to the far reaches of our imagination. Scientists are exploring outward to the ends of the universe and inward to the most basic units of life and matter. Yet one noble and simple tool of the scientist will always be the experiment. Controlled experiments are among the most fruitful avenues for research and problem-solving known to humankind. One way to advance a science career is to develop a strong understanding of the scientific experiment. This exposure may begin in the high school chemistry lab or biology class. And college and graduate students have many opportunities to participate in and even to develop experiments. Working in a laboratory or any setting in which experiments are conducted will provide grounding to a scientist's theoretical endeavors. Learning the history of controlled experiments, and participating in the hands-on evolution of the experimental process, are among the best ways to lay the groundwork for a successful career as a scientist. The work of scientists is distinguished by a faith in experimentation.

Not necessarily... it simply means the earlier theory was based on information available at that time it was proposed. Humans are pretty good at making advances in the scientific world... experiments almost always bring new information to light - allowing us to adapt or update existing information.
It is fair to say that the scientific method is always intended to produce better theories.
