factor in an exeriment that can be manipulated by the experimenter?

Answer 1

Independent variable

Answer 2

A scientific experiment must designed so that the things that change can be identified. These are the variables. The experiment seeks an answer by changing one variable and measuring the change in the other variables. Each experiment has known and unknowns.

The experimenter sets up the experiment for a specific purpose, which could be considered 'the answer.'

Many problems need several experiments to determine the 'answer' that is being sought by the experimenter. Each is a separate though related experiment. The experimenter must design each experiment so that only one variable is changed at the start of the experiment, and all the changes in the other variables are recorded.

There are three kinds of variables:
From GYC.TAS.EDU.AU:

In designing an experiment it is important to consider all the factors that can change in some way. These are called variables.

These are the three types of variables:

1. Independent variable
Also can be referred to as the 'manipulated variable' or the variable which is deliberately altered in some way by the person carrying out the investigation.

2. Dependent variable
Also can be referred to as 'responding variable' or the variable which is measured / directly observed by the experimenter.

3. Fixed / controlled variables
Can be known as either 'Fixed or Controlled variables.' Variables other than the experimental variable could also affect the outcome of the experiment. These need to be controlled or kept constant so that only one variable is being investigated at a time.

Many scientific investigations have fallen down when not every significant variable was successfully controlled.
