Which factor does the investigator change during an investigation?
Do you mean "responding variable"? In a scientific investigation, you try to change only one thing to see what happens. The thing you change is the manipulated variable (also called the independent variable). The result of this change is the responding variable (also called the dependent variable). For example, what if you measure the temperature of a beaker of water, then put it in the refrigerator for 24 hours, then measure again. The change in the temperature from the room to the fridge is the manipulated variable (you controlled it). Any change in the water temperature is the responding variable. It responded to the change you made.
A variable is something that can change in a experiment. A globe can't really change, so no. -yoda
They are synonyms.Some people use the word 'argument' for the 'formal parameter' and 'parameter' for the 'actual parameter', others do on the other way around.PS:example for the formal parameters (function declaration):int myfun (const char *s, int p);example for the actual parameters (function calling):myfun ("Hello", 44);
Pass by value.
Yes, passing a variable by reference gives you a pointer to the original variable, meaning you can change its value from within the function being called and the change will affect the original variable.
An investigator may change the value of a variable parameter during an investigation to test its impact on the outcome or to explore different scenarios. By adjusting the variable, the investigator can gather more information and make informed decisions based on the results of the investigation.
A parameter in an experiment that can change is known as a variable.
The investigator changes the independent variable in an experiment to observe its effect on the dependent variable.
I will change the independent variable in my investigation. This variable is the one I manipulate or control to observe its effect on the dependent variable.
You only change one variable in an investigation because if you change more than one you won't know which change affected the data.
controlled parameters the factor that stays the same in ALL groups variable parameters the factor(s) that change between control groups and variable groups
In an investigation, the variable that you change is called the "independent variable." It is the factor that is manipulated to observe its effect on another variable, known as the dependent variable. The independent variable is crucial for establishing cause-and-effect relationships in experiments.

In an investigation, the independent variable is the factor that is manipulated or changed by the researcher to observe its effects. In contrast, the dependent variable is the outcome or response that is measured to assess the impact of the independent variable. Essentially, the independent variable is what you change, while the dependent variable is what you observe or measure as a result of that change.
When conducting scientific experiments, the researcher manipulates an "independent variable" (i.e., some physical parameter that can be controlled) in order to measure the effects of such manipulation on a "dependent variable" (i.e., the results of changing the physical parameter of interest). For example, one could lower the temperature in a refrigerator (the temperature being an independent variable) and wait to observe when water left in the refrigerator turns to ice (the change from liquid water to the solid form being the dependent variable). Thus, the change in the dependent variable depends on the manipulation of the independent variable. The independent variable is the variable you change, the dependant variable is what changes as a result of what you change.
A variable that is not allowed to change in an investigation is called a "controlled variable" or "constant." These variables are kept the same throughout the experiment to ensure that any observed effects can be attributed solely to the independent variable being manipulated. This helps maintain the integrity and reliability of the experimental results.
the investigator only changes one variable in an experiment because they need to see how that one variable reacts. if you wanted to see how the dependent variable changed but changed the independent variable you would not see how the one variable reacts.
