Bias occurs when scientists' expectations change how the results of an experiment are viewed.
When the expectations of a scientist influence how the results of an experiment are viewed, it can lead to confirmation bias, where the scientist interprets data in a way that confirms their preconceived beliefs. This can result in overlooking contradictory evidence or manipulating the results to fit the expected outcome. It is important for scientists to remain objective and let the data speak for itself to ensure the credibility of their research.
a scientist can do another experiment or change their hypothesis.

One variable at a time.
control variable
The variable that a scientist observes to change while conducting an experiment is called the independent variable. This is the variable that is deliberately manipulated by the scientist to observe its effect on the dependent variable.
All science involves observations. A scientist is either observing the world as it is normally, or is changing something and observing the results of the change. The "change something and observe the results of the change" is called an "experiment". If you're not observing something, then you are not doing "science".

The Answer is Independent Variable.
Answer is : "they analyze all results" Scientists remain objective by not influencing the results of the experiments outside of the established parameters. That means they will not reach in and interfere with the experiment. Also, when they analyze results they attempt to record what actually happened rather than change it slightly to fit what they wanted to see happen.
