1. Reading Assignment (20 points): Read Chapter 11 ,“Tests for Comparing Group Means: Part I” in the Textbook Statistics for Evidence-based Practice in Nursing  (2017).  Also complete the lesson plan by reading the articles and watching the videos.

 

 Answer the following questions in your own words:

1.  After reading the article “HESI Exams An Overview of Reliability and Validity”, discuss the psychometrics of the instrument and determine if it is a good choice as a reliable and valid predictor tool for a medical surgical course.

 

To test the reliability of the HESI Exam before administration, a Kuder Richardson Formula 20 was used. This formula can only be applied to dichotomously scored data, meaning the response to an item or task is always scored as either correct or incorrect. Test for validity is an ongoing process. Content validity refers to the test items' effectiveness in measuring students' basic nursing knowledge and skills. 

 

2. After reading the article “An integrative review of the use and outcomes of HESI testing in baccalaureate nursing programs answer the following questions:
   1. Summarize predictor variables as identified by various authors in the integrative review as being beneficial to BSN students.
   2.  After reading the article do you think that remediation would be beneficial in improving HESI scores in Dr. Koestler’s medical-surgical class? 
   3. Write a null hypothesis and directional hypothesis, in there proper formats,  to test your assumption prior to analyzing the data.

 

2.  SPSS Assignment (80 points)

1. Perform a descriptive analysis of the sample.

Descriptives

 

Descriptive Statistics
	N	Minimum	Maximum	Mean	Std. Deviation
Version 1 HESI	35	58.22	99.42	79.1243	10.83923
At Least 75% of HESI Packet Completed	33	.00	1.00	.3636	.48850
Version 2 HESI	35	55.43	94.12	78.4066	11.06854
Gender	35	1.00	2.00	1.9143	.28403
Valid N (listwise)	33

 

 

2. Perform an dependent t-test in SPSS and test the null hypothesis that you wrote prior to analysis of the data.  Specifically investigate whether completing the remediation improved the Final Exam HESI Scores in the medical surgical class. 
   1. Report the mean and standard deviation and determine if they are significantly different

The mean for remediation completion was .36 and the standard deviation was .49. After completing the remediation, the mean for the final exam hesi score was 78.0 with a standard deviation of 11.2.

 

1. 2. Report the “t” value and degrees of freedom

T value is -40.764 and df is 32.

1. 3. Write your findings in APA format

 

3. Include a cut & paste of the output in this assignment
