What is a scientific investigation?
A scientific investigation is a process involving five steps, which are designed to confirm an idea or opinion put forward based on a question to be answered. This investigation will possibly provide new knowledge or discoveries, correct a previous finding, or further enhance an earlier experiment. Now you can take an in depth look at each step.
How do scientists use the scientific method to solve problems?
When following the scientific method, scientists must ask questions, gather and look at the evidence and determine whether the answers to their questions can be found through that evidence. Scientists also use the method to determine whether all information presented and found can combine to create a logical answer.

What is a treatment level in an experiment?
the specific condition to which a group or participant is exposed in a study or experiment. For example, in a design employing four groups, each of which is exposed to a different dosage of a particular drug, each dosage amount represents a level of the treatment factor.
What is treatment in experimental research design?
An experimental treatment is the intervention of the researcher to alter the conditions of an experiment. This is done by keeping all other factors constant and only manipulating the experimental treatment, it allows for the potential establishment of a cause-effect relationship.
What is treatment in field experimentation?
An experimental treatment is any process/procedure whose effect is to be measured and compared with others. The quantitative or qualitative component of a treatment is called the treatment levels. When there are two or more types of treatments, then each treatment is referred to as factor.

Nicole’s investigation involves two components. The first is a smaller lab-based investigation set to run for a year. For this, Nicole established a number of microcosms – buckets of soil that simulate earthworms’ usual environments. Nicole is able to manipulate variables (such as the type of earthworm species) and make precise measurements of changes to carbon within the soil in each bucket.

How are cohort studies controlled?
Healthy participants are evaluated with regard to the exposure to the effect. Then, the group (cohort) is followed-up for a sufficient period of time with respect to the occurrence of disease, and the progress of disease is studied. The risk of the healthy participants getting sick is considered an incident. In cohort studies, the risk of disease between the groups exposed and not exposed to the effect is calculated and rated. This rate is called relative risk. Relative risk indicates the strength of exposure to the effect on the disease.
Why are prospective cohort studies more valuable than retrospective cohort studies?
Prospective cohort studies are more valuable than retrospective cohort studies: this is because in the former, the researcher observes and records the data.
