Assessment of t-test

Abstract

This research paper is based in the critical statistical analysis of the article: “comparison of nurse educators' and nursing students' descriptions of teaching codes of ethics”, which is based on the nursing education in Finland. This article was retrieved from the Kaplan University. This paper focuses on the statistics used in the article and its appropriateness. The tests used in the article are t-test, ANOVA, Pearson correlation, chi-square, and descriptive. This paper suggests that statistics used is appropriate because mean, standard deviation, and mean difference show that nursing teachers show more extensive significance of teaching than the perception of the student. This paper states that the assumptions of the t-test met with the data used in the article. It also focuses on the display of data and its appropriateness.

As this article is based on the two sample sets given by two different respondents, therefore, this article must use the statistic of sum of differences between the groups by applying ANOVA technique. The t-test that is test for independent gives results about the two independent samples. The use of Pearson correlation gives the statistics of the intensity of the relationship between the two variables ...
