Question

What does it mean to say that a hypothesis is testable and can be falsified? Give an example of an untestable or an unfalsifiable hypothesis.

Answer 1

• A hypothesis is an experiment or trial or attempt or unsure or uncertain or positive answer to a scientific question.
• Hypothesis can be proved or disproved as a result of testing and results.
• A good hypothesis is testable or verifiable and it can be proved to be true or false.if true it must reproduce the results.
  • ex: people exposed to high level of uv rays have a high chances of cancer ratio compared to normal individuals.This incidence can be verified and tested with results from the data collected.
• Falsifiability means that it is false or it might not be false but have to know the methods to prove it. The importance of falsifiability is that science have some thing to say about the real world.
  • ex: global warming by green house gases,all swans are white.
• un testable hypothesis or un falsifiability is impractical or un ethical or untestable hypothesis is that which is not yet tested to be true.
