What are dependent and independent variables in life sciences?
Understand the Problem
The question is asking about the difference between dependent and independent variables specifically in the context of life sciences. This involves understanding how these variables are defined, their roles in experiments, and how they relate to each other in scientific studies.
Answer
Dependent variables are measured responses; independent variables are manipulated to observe their effects.
In life sciences, a dependent variable is what is measured or observed as a response to changes made to the independent variable, which is manipulated or varied to observe its effect.
Answer for screen readers
In life sciences, a dependent variable is what is measured or observed as a response to changes made to the independent variable, which is manipulated or varied to observe its effect.
More Information
In life sciences experiments, researchers often change an independent variable, such as a drug dosage, to observe its effects on a dependent variable, like the severity of a disease.
Tips
A common mistake is confusing which variable is being manipulated and which one is being measured. Always frame the experiment clearly to identify the cause and effect accurately.
