For those who study the behavior of a process, what is the independent variable in a science experiment? The definition is actually a question of some controversy. One school of thought says that the independent variable must change, and therefore the results must be independent.

Yet another school of thought defines the independent variable as something that can be controlled by the researcher, or by the subject in a particular experiment. This concept of the control component is used when there are multiple ways to measure the same thing. One example is the result of a physical test where one form can be performed by a researcher, and the other form can be performed by an experimental subject.

An example of what is the independent variable in a science experiment can be illustrated with computer numerical analysis (CPA). The problem of how to collect data and interpret that data is the concern of every researcher. There are some methods that can be used for obtaining sufficient data without the need to make any adjustments to the experiment. For example, if a researcher wishes to test a hypothesis about the relationship between time and temperature, then it would be reasonable to include information about both temperatures and time in the study. In a study about the relationship between content and behavior, it would make sense to include information about the content, but not about time.

What is the independent variable in a science experiment then? Is it the nature of the experiment, the independence from natural factors, or the subjects included in the study? Most experimenters agree that external factors have an effect on the results of experiments. Some researchers think that the results depend upon the type of factors, while others think that it depends upon the independent variables chosen to perform the experiment. Let’s explore these ideas.

When describing the independent variables in a study, what is meant by independent variable is any factor that could affect the results of the experiment. External factors are those that can change the nature of the experiment without having any influence on the subject(s) in the experiment. One example is the presence or absence of wind. If there is no wind, then the results of the experiment cannot be compared to results obtained when there is wind.

Independencies or conflicts in observations are also considered as independent variables in studies. For example, two experiments are performed at the same time, with the same materials and procedures, and the results are completely different. The one that produces the higher value is considered as the independent variable in the comparison. Of course, these differences could be due to chance. Averaging the independent variable values over all the samples that were part of the experiment can help to confirm the significance of the independent variable.

Another type of independence is called the zero effect independence, which means that there is no relationship between the independent variables and the dependent outcomes. This is very unlikely to occur, as the sample size is small and the number of possible relationships are very high. There are two types of zero-effect experiments: the Bonferroni correction for multiple comparisons, and the false discovery significance. In the Bonferroni correction, for each sample the value of the independent variable is corrected for the sample mean. In the false discovery significance, the experimenter is looking only for the significance of one out of many possible values.

In cases where there is no such thing as absolute independence, but there is still a level of statistical significance, a simple rule is used to determine the level of significance. Asking how much more or less the result is likely to be true in a situation like this can be difficult. However, it is based upon the normal distribution of the independent variable. This ensures that the results of the experiment are normally distributed so that an exact comparison can be made. Thus, in cases where there is no such independent variable, what is the independent variable in a science experiment is determined by a comparison of the independent variables with the dependent variables.
