Dependent and Independent Variables The two articles that I did my research on to identify methodologies and dependent and independent variables are Other mothering as a Framework for Understanding African American Students’ definition of Student-Centered Faculty and A Qualitative Study Exploring Mothers’ Perception of Child Neglect. Both articles use the ethnography participant observation and nonparticipant observation methodologies when summarizing these articles. The first article illustrates

specified on variables. Take x and y to be two variables. A function f may map x to some expression in x. Assigning gives a relation between y and x. If there is some relation specifying y in terms of x, then y is known as a dependent variable (and x is an independent variable). Statistics In a statistics experiment, the dependent variable is the event studied and expected to change whenever the independent variable is altered.[1] Modelling In mathematical modelling, the dependent variable is studied

popcorn one brand at a time. Count the number of popped kernels for each brand. Repeat this process for each brand 3 times. Average the number of kernels popped for each brand to determine which brand pops the best. Variables: Dependent - amount of kernels popped. Independent – the product brand/manufacturer will vary with each test group. Controlled – cooking method, time and temperature will be regulated for each test group. Threats to internal validity: Freshness of popcorn kernels

endorsement on sales. What type of variable is a celebrity endorsement? An independent variable is one that can be manipulated. Independent variables are observed to see if it affects any other variables. A celebrity endorsement can be manipulated by making the celebrity appear to love a product. That is just one example of manipulation. Therefore because the variable can be manipulated, a celebrity endorsement is an independent variable. * In an experiment, this variable is expected to be affected

relationship between two variables where one is dependent and the other is independent. Regression analysis (in statistics), generally, is about any techniques that facilitate modeling and analysis of several variables. It focuses on the relationship between a dependent variable and one or more independent variables (Sykes, 2000). To be specific, regression analysis allows understanding of the typicality of value of the dependent variable changes, while any one of the independent variables is varied. At the

the benefits that variables provide when developing and examining such models. Also, it will discuss the reason why scatter diagrams are used and will describe the simple linear regression model and will refer to multiple regression analysis as well as the potential uses for this type of model. Regression Models Regression models are a statistical measure that attempts to determine the strength of the relationship between one dependent variable (usually denoted

analyzing several variables, when the focus is on the relationship between a dependent variable and one or more independent variables. More specifically, regression analysis helps one understand how the typical value of the dependent variable changes when any one of the independent variables is varied, while the other independent variables are held fixed. Most commonly, regression analysis estimates the conditional expectation of the dependent variable given the independent variables — that is, the
