Mastering Scientific Hypotheses

The purpose of conducting preliminary research is to gather information and form ideas or conclusions based on scientific sources and background knowledge.

Sleep deprivation is considered to have a negative impact on driving performance because it can cause a person to be less alert, leading to decreased reaction time and increased risk of accidents.

Writing a hypothesis in scientific research is important because it helps to clearly state the variables being studied and predict the expected outcome of an experiment.
