Whatever experiment scientists do, when they make a mistake they obviously need to do the whole experiment again!
Making observations
Making observations
is studying, collecting data and recording relevant information. These observations are based on the scientist's senses and are typically objective and unbiased. The scientist may use various tools and techniques to aid in making accurate observations.
The most common human mistake is answering a question without actually knowing the answer. Also know as being too lazy to actually research the answer, or just being stupid. Stupidity is human kind's biggest mistake.
It is more like trial and error. They make the experiment more accurate by the correct measurements and making sure they are using the correct equipment. When something goes wrong they simply repeat the experiment, to make the experiment improve.
Serendipity. That's when a scientist makes a mistake but benefits from it afterwards.
