The difference between these both is that the control is what stays the same in an experiment and the variable is what changes.

Where is the independent variable on a data table?
The independent variable on a data table would be located on the y axis of the data table. The y axis is the bottom of the data table where the names or the objects being tested. The independent variable is dependent on the dependent variable. That's why it is called independent variable.
To eliminate the influence of uncontrolled variables during experimentation?
establish a control group identical to the experimental group except for the variable being tested
What are inferential statistics?
Statistical inference is about testing hypotheses. In order to test a hypothesis, you make a prediction about the observations, contrasting the prediction with what might happen if the hypothesis were not true. The prediction is tested against the observations by calculating a test statistic or inferential statistic. This is a value which is based purely on the observations. If the test statistic is too far from the predicted value then the hypothesis should be rejected in favour of the alternative hypothesis.What constitutes "too far" depends on the presumed distribution of the variable being tested, as well as the degree of certainty required from the test - the power of the test. The latter is a balance between probability of rejecting the hypothesis when it is true and that of not rejecting it when it is false. These outcomes may be weighted according to the risk or costs that a false decision carries.
What is the difference between quantitative and qualitative data in statistics?
Quantitative data is data that is relating to, measuring, or measured by the quantity of something, rather than its quality. ex: the number of people in a townQualitative data is data that can be captured that is not numerical in nature ex: the color of people's skin.Thus, essentially the distinction is that quantitative data deals with numbers and numerical values of what is being tested, where as qualitative data deals with the quality of what is being tested.Qualitative data's description cannot be describe in numbers. Quantitative data's description ca only be described in numbers.
What is the meaning of form a hypothesis?
To form an explanation for an observation or scientific problem that can be tested by further investigation.

What do control groups and experimental groups not have in common?
The variable being tested. The difference between the two groups after the experiment will ideally show some effect by the variable element.
Which of theses factors varies due to effects of the factor being tested in a controlled experiment?
The dependent variable varies due to effects of the factor being tested in a controlled experiment.
