How would you define dependent and independent variables? What is their significance in research? Explain with examples.

Independent variables are the variables that are manipulated to then analyze the effect on the dependent variable. Although, there is not necessarily manipulation of the independent variable but allows for breaking them into groups that fit into specific properties for the study. An example I found to explain this a little clearer is a study of white cell count between the two genders. There is not a manipulation, but the independent variables are male and female and the dependent variable (what is measured) is the white blood cell counts of the genders (StatSoft Electronic Statistics Textbook, 2012).

An example from a previous class would be studying childhood obesity and the relationship to fast-food restaurants close to their school. The independent variable would be the fast-food restaurant in proximity to the school and the dependent variable would be the classifications of the children (normal weight, overweight, obese).

The important of dependent and independent variables is the ability to study if and/or how much of an effect the independent variable has on the dependent variable. In the example I provided the study was to determine if fast-food restaurants in close proximity to schools has an effect on obesity…this allowed the individuals conducting the study to analyze the dependent variables of the different weight classes of the children to determine if and/or how much the independent variable has on the children.
