Astronomer.
The variable that a scientist observes to change while conducting an experiment is called the independent variable. This is the variable that is deliberately manipulated by the scientist to observe its effect on the dependent variable.
A scientist who studies animals is called a zoologist.
A variable
The factor that a scientist observes or measures in an experiment is known as a variable. Specifically, the dependent variable is the one that is measured to assess the effect of changes made to another variable, called the independent variable. By carefully controlling and observing these variables, scientists can draw conclusions about cause-and-effect relationships in their experiments.
They are called Biologists. Bio means life. Biology means the study of life.
The variable that a scientist observes to change in an experiment is called the responding variable, often referred to as the dependent variable. This variable is affected by changes made to the manipulated variable or independent variable. In essence, the responding variable provides the data that indicates how the changes in the independent variable influence the outcome of the experiment.
The prefix for "animal" is "zoo-" so they are called zoologists.
It is called Taxonomy.
