**MIKVO011p**Nursing research - lecture

Basic experience with computer. **Course Enrolment Limitations**- The course is only offered to the students of the study fields the course is directly associated with.

**fields of study / plans the course is directly associated with**- Intensive Care (programme LF, N-IP)
- Intensive Care (programme LF, N-SZ)

**Course objectives**- The course introduces data analysis to students of clinical study specialisations. Students will be trained in all aspects of data processing and its statistical analysis (descriptive statistics, one sample and two sample tests, categorical data analysis, ANOVA, correlation analysis, data visualisation).
**Learning outcomes**- At the end of the course the students are able to:

- define structure of dataset for statistical analysis;

- visualize the data and interpret data visualisation;

- identify correct methods of descriptive statistics;

- formulate hypothesis for statistical testing;

- select the correct statistical tests for hypotheses confirmation/refusal;

- interpret results of statistical evaluation, both analysis of own data and statistics in scientific literature;

- assess the applicability of statistical methods on various types of data. **Syllabus**- 1. Data processing – principles of correct data manipulation. MS Office Excel – appropriate tool for storing, organizing, and manipulating data.
- 2. Introduction to statistics. Data types in medicine and biology; nominal, ordinal, continuous variable. Visualization of quantitative and qualitative (categorical) variables.
- 3. Descriptive statistics. Mean, median, quantiles, variance. Frequency table.
- 4. Distribution of continuous variables. Normal distribution, log-normal distribution.
- 5. Principles of hypotheses testing. Definition of null and alternative hypothesis. Significance level. Type I and type II error.
- 6. Graphical examining of normal distribution (histogram, normal-probability plot). Shapiro-Wilk test – a test of normality.
- 7. Parametrical tests: t-tests. One-sample t-test, two-sample t-test, t-test for dependent samples.
- 8. Analysis of variance ANOVA.
- 9. Nonparametrical tests: one-sample Wilcoxon test, Mann-Whitney U test, Wilcoxon test for dependent samples, Kruskal-Wallis test.
- 10. Definition of contingency table and its analysis: Pearson chi-square test, Fisher exact test, McNemar test.
- 11. Correlation. Pearson correlation coefficient, Spearman correlation coefficient.
- 12. Introduction to regression analysis. Linear regression.
