The dependent variable , which is the one being measured.
It is usually recommended to test one variable at a time in an experiment to accurately determine its effect. This helps to isolate the impact of that specific variable and avoid confounding results from multiple factors changing simultaneously.
A controlled experiment allows the scientist to isolate and test a specific variable by keeping all other variables constant. This helps to determine the direct impact of the variable being tested on the outcome of the experiment. Controlled experiments are essential for establishing cause-and-effect relationships in scientific research.
The variable deliberately changed in an experiment is called the independent variable. This variable is manipulated by the researcher to observe its effects on the dependent variable, which is the outcome or response being measured. By controlling and changing the independent variable, researchers can determine its influence on the dependent variable.
Manipulated variable is also known as the independent variable. The independent variable may determine if a seed germinates. Examples of manipulated variables for seed germination include: water, suitable temperature and air/oxygen. These basic variables are also the most important in seed germination.
After calculating the mean and standard deviationvalues each value of the independent variable in the data, these are a few common tests that are used to further analyse the data and highlight its significance:1) Pearson Correlation Coefficient- This is to test for a strong/weak positive/negative correlation between the independent variable and the dependent variable. However, correlation does not necessarily imply causation.2) t-test- This post-hoc test is used to determine the level of significance of the difference between two sets of data.3) Chi2 test- This test tests for whether the difference in Expected and Observed values are significant or not.4) Analysis of variance (ANOVA)- This is like a massive t-test to test an entire set of data, without inflating the error of the analysis results. This is usually coupled with Tukey's Honest Significant Difference test.
the test variable is the independent variable.

The variable that is changed to test a hypothesis is called the independent variable. It is manipulated by the researcher to observe its effect on the dependent variable, which is the variable being measured or observed in response to the changes in the independent variable.
