It depends on whether the heart beat is being changed (dependent variable) or if the heart beat is changing something else (independent variable) P.S. The independent variable is the thing that was changed, while the dependent variable is the data collected through observations and measurements ( aka how the independent changed the dependent).
The variable observed during an experiment is called the dependent variable. It is the one being measured or tested in response to changes in the independent variable.
An experiment in which only one variable changes is called an "controlled experiment" or "single-variable experiment." In this type of experiment, the researcher manipulates one variable (independent variable) while keeping all other variables constant to determine its effect on the outcome (dependent variable). This approach helps to isolate the impact of that single variable on the results.
Well in the case that it does have a variable, even just one, it would still be a variable experiment because that one part of the experiment may still cause a different effect/result when changed!!!
A single-variable experiment, also known as a one-factor experiment, is one in which only one variable is manipulated at a time while keeping all other variables constant. This allows researchers to isolate the effects of that specific variable on the outcome of the experiment.
a controlled experiment
In Fleming's experiment, the variable was the type of bacteria being tested for their susceptibility to penicillin.
Indpendent variable
a controlled experiment
The variable observed during an experiment is called the dependent variable. It is the one being measured or tested in response to changes in the independent variable.

a controlled experiment
An experiment in which only one variable changes is called an "controlled experiment" or "single-variable experiment." In this type of experiment, the researcher manipulates one variable (independent variable) while keeping all other variables constant to determine its effect on the outcome (dependent variable). This approach helps to isolate the impact of that single variable on the results.
In an experiment, the independent variable is altered, and the effect observed is the dependent variable, or outcome. The controlled variable is intended to be kept the same throughout the experiment so that changes in it do not affect the results.
The dependent variable is the variable that can change in an experiment.
The independent variable in the Tootsie Pop experiment is the type of candy coating on the lollipop - whether it is smooth or bumpy.
Well in the case that it does have a variable, even just one, it would still be a variable experiment because that one part of the experiment may still cause a different effect/result when changed!!!
