Independent and Dependent Variables A dependent variable? Yes, there can be more than one dependent variable. In our example, for instance, the growth rate of the plants might be one dependent variable and the overall height of the plants might be another dependent variable. Both of these variables depend upon the independent variable.

Dependent Variable There may be more than two dependent variables in any experiment. Dependent Variable Examples. A researcher might wish to establish the effect of fertilizer on the rate of plant growth; amount of fertilizer is the independent variable. They could regard growth as height, weight, number of fruits produced, or all of these. A whole range of dependent variables arises from one independent variable.

Price Competition Among Retailers Of Coca Cola Products In Ibadan Metropolis, Nigeria Agboje Ifeoma Anestinaa Independent variables are isolated and controlled by the researcher during the experiment or the research study. The dependent variable changes as a result of, or in response to, the variations in the dependent variable.

- These changing quantities are called variables. A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed/controlled by the scientist.To ensure a fair test, a good experiment has only one independent variable.or example, if you open a faucet part way (the independent variable), the quantity of water flowing (dependent variable) changes in response--you observe that the water flow increases. Experiments also have constants or controlled variables.

- For example, if you open a faucet (the independent variable), the quantity of water flowing (dependent variable) changes in response--you observe that the water flow increases. The number of dependent variables in an experiment varies, but there is often more than one. Experiments also have controlled variables.Controlled variables are quantities that a scientist wants to remain constant, and he must observe them as carefully as the dependent variables.ost experiments have more than one controlled variable. Some people refer to controlled variables as constant variables.. In a good experiment, the scientist must be able to measure the values for each variable. Weight or mass is an example of a variable that is very easy to measure.

Publication 463 (2017), Travel, Entertainment, Gift, and Car Expenses Jan 4, 2016. There should be one or more dependent variables in an experiment. There is supposed to be one independent variable (the variable that is different from one another) in an experiment, or else it will throw off the experiment. If you have more than one, the result would be unclear.

Dependent Variable vs. Independent Variable in Marketing An independent variable is an input to a process or analysis that influences the dependent variable. While there can only be one dependent variable in a study, there may be multiple independent variables.ts name comes from the fact that it depends on or responds to other variables. Typically, the dependent variable is the result you want to achieve. In marketing, the results desired are tied to sales revenue.

- Background: When conducting experiments, one needs to deal with variables, those factors or elements that are likely to vary or change. A typical study has an independent variable and a dependent variable. The independent (or manipulated) variable is something that the experimenter purposely changes or varies over the course of the investigation. The dependent (or responding) variable is the one that is observed and likely changes in response to the independent variable.

Introduction to Regression (If the split between the two levels of the dependent variable is close to 50-50, then both logistic and linear regression will end up giving you similar results.) The independent variables used in regression can be either continuous or dichotomous.

- Explain why it is important to use only one independent variable at a time in a given investigation. Answers. If you use more than one independent variable at a time, and will observe a change, you will not know which variable contributed to a changed result. Comments Report

Why is it acceptable to have more than one dependent variable? You can have more than one independent variables. especially when studying interactions. A good example would be the interaction of Race/ethnicity and age on HIV infection and HIV progresion. So your independent variables here would be Race/ethnicity and age and your dependent would be HIV infection and progression.

- The dependent variable is the number of wrong turns (errors) the rats make on a trial. As time and number of practice trials increases, the number of errors decreases. Theoretically, an internal state of “learning” intervened between the independent and dependent variables.

- In such an experiment, an attempt is made to find evidence that the values of the independent variable determine the values of the dependent variable. The independent variable can be changed as required, and its values do not represent a problem requiring explanation in an analysis, but are taken simply as given. The dependent variable, on the other hand, usually cannot be directly controlled.

- An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist. To ensure a fair test, a good experiment has only one independent variable. As the scientist changes the independent variable, he or she observes what happens.

Two Level Factorial Experiments In two level experiments, the ANOVA model requires only one indicator variable to represent each factor for both qualitative and quantitative factors. Therefore, the notation for the multiple linear regression model can be applied to the ANOVA model of the experiment that has all the factors at two levels.

Multinomial logistic regression When using multinomial logistic regression, one category of the dependent variable is chosen as the reference category. Separate odds ratios are determined for all independent variables for each category of the dependent variable with the exception of the reference category, which is omitted from the analysis.

- If the user moves the name of only one variable the box labeled “independent variable(s)”, SPSS performs a bivariate regression analysis. If the names of more than one variable are moved to the “independent variable(s) box, SPSS performs a multiple regression analysis. 3. Click OK Four output tables result.

Linear Regression In simple linear regression a single independent variable is used to predict the value of a dependent variable. In multiple linear regression two or more independent variables are used to predict the value of a dependent variable. The difference between the two is the number of independent variables. In both cases there is only a single dependent variable.

Independent, Dependent and Extraneous One is called the dependent variable and the other the independent variable. In an experiment, the researcher is looking for the possible effect on the dependent variable that might be caused by changing the independent variable.• Independent variable (IV) : Variable the experimenter manipulates (i.e. changes) – assumed to have a direct effect on the dependent variable.n an experiment, the researcher is looking for the possible effect on the dependent variable that might be caused by changing the independent variable. • Independent variable (IV) : Variable the experimenter manipulates (i.e. changes) – assumed to have a direct effect on the dependent variable.

Independent and Dependent Variables Independent and dependent variables are related to one another. The Independent part is what you, the experimenter, changes or enacts in order to do your experiment. The dependent variable is what changes when the independent variable changes - the dependent variable depends on the outcome of the independent variable.

- Multicollinearity can cause strange results when attempting to study how well individual independent variables contribute to an understanding of the dependent variable.

- There may be more than one dependent variable and/or independent variable. This is especially true if you are conducting an experiment with multiple stages or sets of procedures. In these experiments, there may be more than one set of measurements with different variables.

Introduction to Regression Because of this, an independent variable that is a significant predictor of a dependent variable in simple linear regression may not be significant in multiple regression (i.e., when other independent variables are added into the equation).
