Choose all the answers that apply. Check all the statements that are correct. An independent variable is the variable which is changed. The dependent variable is the variable which is observed as a result of the change. Disproving a hypothesis means it cannot be tested again. Experiments are usually published to communicate findings to the scientific community. If data can be repeated, it cannot be trusted.

Respuesta :

The dependent variable is the variable which is observed as a result of the change

Experiments are usually published to communicate findings to the scientific community.

Explanation:

Before an experiment is done it is significant that background research is conducted to fully understand the dynamics and potential relationship between the variable to be tested. This also gives insight into how to design the experiment and reduce failure rate. This background research also guides how to set the null hypothesis.

Among the variables, the one being manipualted to affect another variable is the independent variable while the dependent variable is the one that is affected by the changes in the independent variable. The dependent variable is what is observed and measured.

Depending on the results, the null hypothesis can be accepted or rejected.

Scientific reports after the experiments should exquisitely describe how the experiment was conducted and how the conclusion was achieved. This ensures the experiment is reproducible such that it is subjected to peer-review. Peer-review is a way of quality assurance within the scientific community.
