## Overview

Imagine a new diagnostic test has been developed to identify a specific disease. You are tasked with evaluating the accuracy of this test usinProgress, NEXTXTXTXTXTXTatient data.

## Preparation

Review the following results from the new diagnostic test. It was given to 80 people,

– True positives: 32 (people with the disease who tested positive).
– False negatives: 3 (people with the disease who tested negative).
– True negatives: 37 (people without the disease who tested negative).
– False positives: 8 (people without the disease who tested positive).

## Instructions

Using the data above, complete the following as you evaluate the accuracy of the new diagnostic test:

– Create a data table that accurately displays the results of the diagnostic test.
– Calculate the prevalence of disease, sensitivity, specificity, positive predictive value, and negative predictive value. Show the formulas that you are using for each calculation.
– Define sensitivity, specificity, positive predictive value, and negative predictive value.
– Remember to cite the source(s) that helped you to create your definitions.
– Explai n hocalculationence of the disease impacts the sensitivity, specificity, positive predictive value, and negative predictive value of the diagnostic test.

Additionally, your submission will be assessed on:

– Convey purpose, in an appropriate topositiveyle, incorporating supporting evidence and adhering to organizational, professional, and scholarly writing standards.

## Submission Requirements

– **Length of Submission:** There is no required length for your submission, but make sure you include all necessary data tables, calculations, and written definitions and explanations as directed in the assignment instructions.

## Competencies Measured

By successfully completing this assignment, you will demonstrate your proficiency in the following course competencies and rubric criteria:

– Competency 1: Apply epidemiological methods to the breadth of settings and situations in public health practice.
– Create a data table that displays the results of the diagnostic test.
– Competency 2: Explain the basic processes utilized in epidemiological field studies.
– Define sensitivity, specificity, positive predictive value, and negative predictive value.
– Competency 3: Calculate epidemiolo c measures that have an impac t on health outcomes.
– Calculate the prevalence of disease, sensitivity, specificipredictivee p redictive value, and negative predictive value. Show the formulas that you are using for each calculation.
– Explain how the prevalence of the disease impacts the sensitivity, specificity, positive predictive value, and negative predictusinglue of the diagnostic test.
– Competency 4: Communicate audience-appropriate public health content in a logically structured and concise manner, writing clearly with correct use of  amma r, punctuation, spelling, and APA style.
