Nimmy James 2 posts Re: Topic 8 DQ 1 Dependent variables are otherwise known as the outcome variables. The value of the dependent variable depends on the value of other variables. In research, the dependent variable takes on different values in response to the independent variable. The independent variable is otherwise known as the experimental or predictor variable. It is manipulated in the research to observe the effect on the dependent variable. The value of an independent variable does not rely on other variables as the independent variable can stand alone (Kusurkar, Ten Cate, van Asperen, & Croiset2011). Using my EBP as an example, the dependent variable in the study is the rate of pressure ulcers in the facility. To measure this, I will need to collect data on the number of pressure ulcers in past three years. This data will help me to monitor how manipulating the independent variables affect pressure ulcer rate which is a dependent variable. The independent variables in this study include nurses’ knowledge about wound care and how effects of protein intake with wound healing. The EBP will manipulate theses independent variables by educating nurses on nutritional impact on pressure wound healing and by implementing extra protein into their daily diet. With a questionnaire, I will be able to collect data on nurses’ knowledge about the topic which help with planning the education and training.
