Webb10 aug. 2024 · A properly designed and executed experiment enables a scientist to determine whether the original hypothesis is valid. In the case of validity, the scientist can proceed to step 5. In other cases, experiments may demonstrate that the hypothesis is incorrect or that it must be modified, thus requiring further experimentation. WebbA hypothesis must be valid and specific enough to be tested scientifically. A non-experimental hypothesis is an educated assumption about how events and actions might be related. This hypothesis is employed in a non-experimental design that focuses on the relationship between two variables and a subject, and events cannot be altered.

Such evidence is expected to be empirical evidence and interpretable in accordance with scientific methods. Standards for scientific evidence vary according to the field of inquiry, but the strength of scientific evidence is generally based on the results of statistical an… Webb15 sep. 2024 · A hypothesis is a tentative explanation that can be tested by further investigation.
