independent and dependent variables Most healthcare professionals have heard the terms independent variable and dependent variable (Kleinbaum, Kupper, Muller, & Nizam, 1998; Polit, This deep dive post explains the concepts of single and multiple research variables and, importantly, how to identify the independent and dependent variable in quantitative research studies. One of the dependent variables that I would collect in the evidence based projects are the health outcomes of the surgical patients undergoing surgery in the healthcare organization. But don’t give up! However, discrete variables. Experiment 1: You want to figure out which brand of microwave popcorn pops the most kernels so … Below are overviews of three experiments, each with their independent and dependent variables identified. Independent and dependent variables are concepts with which many nursing students struggle. Think about the fact that we are in case C → Q!

To evaluate the outcomes of the EPB projects, collection of dependent and independent variables in the project is essential (Watson, Stimpson, Topping & Podorock, 2002). As a result of the formula used to compute the correlation coefficient, its value will always lie between -1 and 1. Hey, I did, too! Given the values of two variables for a set of observations (X is usually used to denote the independent variable and Y for the dependent variable), Pearson’s correlation coefficient can be calculated using a mathematical formula.
