He now wants to ensure his results are reproducible.Which one of the following should Houtan now do to show reproducibility in this experiment?Repeat using same method and equipment, then compare results to see if they are similar.Compare results against other students using different method and see if they are similar.Compare results against other students using the same method and see if they are similar.Repeat using different method and equipment, then compare results to see if they are similar.I DON'T KNOWSUBMIT ANSWER

Science is knowledge gained through repeated experiments or observation. To be convincing, a scientific paper needs to provide evidence that the results are reproducible. How are repeated trials different from replication?Group of answer choicesRepeated trials are not recorded in any kind of data chart. Replication may use several data chartsThe same scientists conduct repeated trials. Replication occurs when another scientist repeats an experimentRepeated trials require the use of a calculator. Replication requires the use of a computerRepeated trials are based on observations. Replication is based on evidence

Discuss the validity of the method and hypothesis provided above. Suggest one improvement for the experiment.

All of the following are correct, except:Replication is when a second scientist repeats the first scientist's experiment to see if they get the same results.Reliable results are those experimental results that can not be trusted.Scientists often plan investigations or experiments to find the answers to questions they have about the world around them.Repetition is when a scientist performs multiple trials in an experiment.Preview
