This figure shows graphed medical research results from a study on a new vaccine. The research was done in an effort to determine if a new vaccine would be effective at preventing potentially dangerous rotavirus infections in infants. Green data bars represent occurrence of infant cases that had normal rotavirus strains that aren't critically dangerous. Blue data bars represent occurrence of infant cases that had more dangerous rotavirus strains that can hospitalize or lead to fatality of infants

-In the graph,the X-axis is showing different doses of vaccine,including "placebo," "low," "medium" and "high." These levels of vaccine were applied to different groups of babies to test if and how much the vaccination helped reduce the incidence of rotavirus,an illness that can quickly dehydrate infants to critical or fatal levels.These doses represent

Quizplus · Accepted Answer

The different doses of vaccine shown on the X-axis of the graph represent the independent variable in the medical study. This is because the researchers are manipulating the dose of the vaccine to observe the effect on the dependent variable, which is the incidence of rotavirus. The standardized variable, also known as the controlled variable or constant, would be factors that are held constant throughout the study, such as the age range or health condition of the infants. The control group of the study would be a group of infants who are not given any vaccine or given a placebo, to serve as a comparison to the vaccinated groups. However, the graph does not represent the control group itself, but rather the results of different doses of the vaccine on the dependent variable.
