how science works?
Question 1 of 5
What’s the main way researchers advance scientific knowledge?
- They memorize facts from textbooks.
- They ask questions and test their ideas with observations and experiments. Then, they redo their studies (or see if others can) and see if the results are the same.
Question 2 of 5
How can you tell if the results from a scientific study are strong?
- An important scientist expresses confidence in the study’s results.
- The study comes to the same conclusion as multiple previous studies by different scientists.
- If it is the newest study, it is the most accurate.
Question 3 of 5
A study is reproducible when scientists are able to use the exact same data and computer code to get the same results (as defined in the report, Reproducibility & Replicability in Science). Why is it important to make sure studies are reproducible?
- It helps scientists verify that a study’s analysis is valid
- It helps other scientists use the work as a stepping stone for future studies
- Both a and b
- None of the above
Question 4 of 5
Replicability is when scientists repeat a study using similar methods, collect new data, and get similar results (as defined in the report, Reproducibility & Replicability in Science). Why is replicability important for science?
- It helps build confidence in a body of knowledge
- It helps scientists get credit for their work
- It helps scientists get more funding for their work
Question 5 of 5
What does it mean if two studies disagree?
- One of them is wrong. Ignore the one that is older.
- It’s useful to find out why. This can help improve scientific methods and even lead to new discoveries.
