A variable is an event, idea, value or some other object or category that a researcher or business can measure variables can be dependent or independent dependent variables vary by the factors. Independent variable the one factor that is changed by the person doing the experiment (what we know before the experiment) where is the dependent/response variable usually plotted on the y-axis of a graph.

The independent variable, also known as the manipulated variable, is the factor manipulated by the researcher, and it produces one or more results, known as dependent variables. Express the research question in a measureable hypothesis statement (ensure that the hypothesis statement includes the independent variable and the dependent variable you identified in items 1 and 2 above. A research approach in which one variable (called an experimental, treatment, independent, or explanatory variable) is manipulated and the effect on another variable (dependent variable) is observed. A marketing dependent variable b dependent independent variable c control data from marketing 421 at university of phoenix. Describe how you would do a two sample hypothesis test select the variables (dependent and independent ones) and briefly set up the test include any.
Free practice questions for high school physics - understanding independent and dependent variables includes full solutions and score reporting. (2 pts) the independent variable is the variable representing the value being manipulated or changed and the dependent variable is the observed result of the independent variable being manipulated in the experiment the level of ecb infestation is the independent variable and the dependant variable is the yield of the corn plants in term of. Identify the independent & dependent variable(s) for this study describe the scale of measurement used for the independent variable describe the scale of measurement used for the dependent variable. The independent variable is the variable representing the value being manipulated or changed and the dependent variable is the observed result of the independent variable being manipulated in the experiment the level of ecb infestation is the independent variable and the dependant variable is the yield of the corn plants in term of kernel. In an experiment, the independent variable is the variable that is varied or manipulated by the researcher the dependent variable is the response that is measured.
Part c: regression and correlation analysis use the dependent variable (labeled y) and the independent variables (labeled x1, x2, and x3) in the data file. Intervening variables are variables that occur between the manipulation of the independent variable and the measurement of the dependent variable and that contaminate the relationship between the two. Marketing research employs a statistical tool called regression analysis to measure the strength of the relationship between the dependent variable and the independent variables. Eg regarding the alcohol example, the independent variable is the amount of alcohol consumed, the dependent variable is the performance on the memory task, and a confounding variable may be underlying alcohol tolerance.
Independent and dependent variable examples in a study to determine whether how long a student sleeps affects test scores, the independent variable is length of time spent sleeping while the dependent variable is the test score. In any experimental design, a researcher will be manipulating one variable, the independent variable, and studying how that affects the dependent variables a failure to isolate the controlled variables will compromise the internal validity.

Specifically, why did you choose the dependent variable you chose indicate the general model that you are going to estimate discuss what you think the relationship is between the dependent variable and the independent variables, and what that leads you to conclude about the expected signs of the coefficients in the model.
