What else can I help you with?
To eliminate the influence of uncontrolled variables during experimentation?
establish a control group identical to the experimental group except for the variable being tested
Where is the independent variable on a data table?
Ah, the independent variable is typically found on the left side of a data table. It's the variable that you can control or manipulate to see how it affects the dependent variable. Just remember, like a happy little tree, the independent variable helps guide the direction of your experiment.
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 is the meaning of controlled experiment?
The variable being tested is controlled.
How many variable are tested in controlled experiements?
2
What factor Is being tested in a controlled experiment?
The factor being tested is the dependent variable.
What is an experiment in which one variable is tested at a time?
Controlled Experiment :]
What condition or factor is being tested in an experiment?
controlled variable
What is the part of the experiment that is changed and tested?
The part of the experiment that is changed and tested is called the independent variable. This variable is manipulated or controlled by the researcher to observe its effect on the dependent variable.
What is the part of an experiment is not being tested and is used for comparison?
Controlled Variable
Which of these factors varies due to effects of the factors being tested in a controlled?
the variable
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.
The one factor that differs in a controlled experiment?
In a controlled experiment, the one factor that differs is the independent variable. This is the variable that is deliberately changed or manipulated by the researcher in order to observe its effect on the dependent variable. The goal of a controlled experiment is to isolate the impact of the independent variable on the dependent variable while holding all other variables constant.
What is the factor being controlled in a experiment?
The factor being tested is the dependent variable.
What is the factor tested in an experiment called?
The factor tested in an experiment is typically called the independent variable. This is the variable that is deliberately manipulated or changed by the researcher to observe its effect on the dependent variable.
