Last update: Mgr. Ing. Marek Vranka (30.09.2018)
The subject "Basic Statistics" introduces students to basic statistical terminology and concepts. Emphasis is placed on understanding the difference between descriptive and inductive statistics, understanding the principles of null-hypothesis significance testing, and applying the most widely used bsic statistical techniques to analyzing empirical data in the field of psychology.
Aim of the course -
Last update: Mgr. Ing. Marek Vranka (30.09.2018)

The aim of the course is that students acquire the knowledge of principles of statistical analysis of empirical data in various areas of psychology and gain the ability to correctly interpret the results of statistical analyses.
Note: This course does not aim to introduce data analysis methods necessary to examine more complex datasets, nor to optimize the application of statistical methods depending on the specific data. This essential part of the statistical analysis is the main aim of the course in the follow-up Master's study.
Learning outcomes and competences: After completing the course, a student can describe basic methods of descriptive statistics; explain the concept of random variables – i.e., statistics as a function of sample data; knows the purpose and basic principles of inductive statistics – i.e., confidence interval calculation and null-hypothesis testing; knows basic parametric tests (such as t-tests and chi-square tests, correlation coefficient significance tests), their assumptions and situations suitable for their application.
Learning outcomes: After completing the course, the student is able to quantify (using a calculator, Excel or an appropriate statistical software) descriptive statistical characteristics of a given data set; apply a suitable statistical technique to verify simple research hypotheses depending on the data situation (i.e., its design and type of variables); correctly interpret results of basic statistical analyzes in the academic literature.

(For a detailed syllabus see https://dl1.cuni.cz/course/view.php?id=3253)

 
* Introduction to statistics

 
The role of mathematical statistics in psychology - basic concepts of statistics - problems of quantification in psychology - types of scales

 

* Descriptive statistics

 
a) Distribution and basic statistical characteristics: empirical distribution - graphical representation - quantils - basic statistical characteristics - standard scores (z-transformation, standard scales used in psychology).

 
b) Characteristics of statistical dependence: data matrix - two-dimensional distribution - concept of statistical dependence - Pearson correlation coefficient - Spearman correlation coefficient - other correlation coefficients - significance tests of correlation coefficients.

 

* Inductive statistical methods

 
a) Principles of statistical induction: base set (population) and samples.

 
b) Point and interval estimation - confidence interval.

c) Testing of statistical hypotheses: null and alternative hypothesis - test characteristics - level of significance - one-sided and double-sided test - p-value - z-test - statistical power.

 
d) Some basic statistical tests: one-sampling t-test - two-samples t-test - paired t-test (for dependent samples) - linear regression - chi-square test of good fit - chi-square test of independence - Mc-Nemar test of symmetry - Fischer exact test - basics of non-parametric tests and ANOVA
