Dr. Bob hypothesizes that drug X causes cuts to heal more quickly. He performs a medical experiment on a group of 100 people and
confirms his original hypothesis. In the control group, a 1 cm cut took seven days to heal. In the experimental group, a 1 cm cut took four days to heal. What should Dr. Bob do next? A) Repeat the experiment for accuracy. B) Begin selling drug X to the public. C) Write a scientific theory about drug X. D) Publish the results of the experiment in a scientific journal.
In the given question doctor used the scientific method to understand and explain the natural phenomenon.
The scientific method involves various steps like making an observation followed by background research, predicting a hypothesis and performing tests to test the hypothesis. These steps have been performed by the doctor.
After these steps the doctor will analyse the result and reach to the conclusion. This would be followed by publishing the results in a scientific journal where it would be reviewed by the fellow scientists.
Therefore, the next step will be publishing the result and thus option-D is the correct answer.
Explanation: When trying to establish the level or extent of correlation or relationship which exists between two variables, the variables are classed as independent and dependent variables. The independent variable is referred to as the variable which causes a change in the value of the other variable (dependent variable). It is also known as the explanatory or predictor variable as it lead to changes in the dependent or predicted variable. In the scenario above, the independent variable is sunlight whose impact leads to changes in the growth level of the plant.
