One kind of evidence is physical evidence, which includes tangible items that can be collected and analyzed, such as fingerprints, DNA, or weapons. This type of evidence can provide concrete support for claims made in legal cases, helping to establish or refute connections between suspects and crime scenes. Physical evidence is often considered highly reliable due to its ability to be scientifically tested and verified.
Hypotheses can be either rejected or accepted based on the results of an experiment or study. If the evidence supports the hypothesis, it is accepted; if the evidence contradicts it, the hypothesis is rejected. Ultimately, the decision is based on statistical analysis and the strength of the data collected.
