Words such as statistics, theory, and variables associated with the process of research often evoke fear, anxiety, and horror in many nurses. However, research is an integral component of nursing practice, especially with the current focus on evidence-based practice (EBP)—the use of the best research evidence to guide nursing practice and the achievement of the best patient outcomes. Clinical nurses drive EBP and the movement of new knowledge from the pages of nursing journals into nursing care activities. But nurses frequently cite a lack of knowledge about research terms and concepts as a barrier to actively engaging in the process of finding evidence and using it in their practice.
This crossword puzzle is designed to familiarize you with common research terms and concepts. A crossword puzzle is a fun and active learning opportunity that can be completed independently or in teams. Solving the clues requires you to use higher-level thinking skills, including analysis, synthesis, and application of both existing and new knowledge. Let's get started!

52. This type of effect is the effect of an independent variable on a dependent variable, after controlling for the effects of one or more covariates through multiple regression or ANCOVA.
53. Format of a research project; identifies the approach, sampling technique, amount of control, when and how data are collected, and analysis strategies.
56. A theoretical distribution is referred to as a normal or bell-shaped _____.
57. Individual characteristics of the subjects; may include, gender, age, education, or income.
