Introducing Statistics for the DNP
A research problem statement identifies an area of need in which there is a gap in knowledge or practice and interest by a nurse researcher. Either from a hypothetical or real-world experience, nursing research problem statements help to focus the research purpose and guide the study of the problem.
In this discussion, you will identify a nursing problem to analyze the potential impact for positive change and explore tools used to examine it in the selected research.

Required Power point
To prepare:
· Review the “Fall” articles from Week 1.
· Complete the Week 2 Basic Research Principles: Introducing Statistics Quiz.
By Day 3 of Week 2
Post a response to the following prompts:
· Identify nursing problems implicit in the nursing research study and the QI DNP project.
· Describe how the nursing problems define the gap in knowledge (research) and the gap in practice (QI and DNP projects). Compare and contrast how the problems are presented and potentially influence a positive nursing practice change.
· Identify one key measurement/variable used in each of the three studies/projects.
· Critique the question development tool presented in terms of the problem, the EBP question, and the measurement (Hicks, 2024).
By Day 6 of Week 2
Read a selection of your colleagues’ posts and respond to at least two of your colleagues on two different days by expanding upon their reflections, making connections to your perceptions, and offering additional insights.

NURS 8211 Research for an evidence-based practice Week 2: Basic research principle; introducing statistics
Basic research principles includes the use of statistics in quantitative studies.
1
Week 2: Introducing statistics for the dnp
Objectives
Differentiate between inferential and descriptive statistics
Identify a nursing problem statement and describe how the problem relates to the research question or practice-focused question
Identify key measurements/variables related to a research study, a QI project, and a DNP project
Determine how hypothesis testing principles can apply to evaluating change in practice whether research, quality improvement or evidence-based practice
Problems and a gap in practice
Identifying the problem and the measurement associated with it is an important process
Problems may relate to:
Poor outcomes
A practice that is outdated or ineffective in addressing a problem
Problems and their solutions
Hicks, T. (2024) increased CLABSI rate at the site. DNP project that explored a gap in practice: the incidence of CLABSI
Emsden et al., (2020) practice using tools that require a verbal response to evaluate pain in patients who are nonverbal (intubated patients, patients who are unconscious). A research study that explored a knowledge deficit: how to evaluate pain in nonverbal patients.
How does measurement play into these?
The incidence of CLABSI in patients at the site.
What tools are currently in place to evaluate pain in nonverbal patients? Is there a better way?
3
Measurement vs. variables
Implementing a bundle to combat CLABSI
Measure CLABSI
Measure the components of the bundle
Compare pre to post:
For the incidence of CLABSI
For compliance with the bundle
Hicks, T. (2024)
Measurement vs. variables
Developing Criterion Validity for the Critical Care Pain Observation Tool (CPOT) to measure pain in nonverbal patients
Compared CPOT to Behavioral Pain Scale and patients’ self report in 60 patients using 480 pain observations simultaneously with 2 raters
Feasibility: measured by nurses
Pain evaluation: measured in patients
5
Descriptive vs. inferential statistics
Descriptive statistics are useful to describe the sample characteristics
Inferential statistics are useful to infer results from a sample to a population
Both can be used in published research.
Descriptive statistics can be used to describe the sample on key characteristics
Inferential statistics can be used to determine whether or not you can make inferences about the population from a sample. Is the result due to chance or is there someway to use the information to predict from the sample to the population?
6
From problem to a practice-focused question
Requires thoughtful analysis on what is the nature of the problem, and what is currently in place to address the problem.
What is the gap in practice?
What does current research evidence say about what works and what doesn’t to solve the problem?

It is not too soon for you to start thinking about a problem
