1 Why statistics?

Part 1 Descriptive statistics
2 Some basics: Variability and measurement
3 Describing variables: Tables and diagrams
4 Describing variables numerically: Averages, variation and spread
5 Shapes of distributions of scores
6 Standard deviation and z-scores: Standard unit of measurement in statistics
7 Relationships between two or more variables: Diagrams and tables
8 Correlation coefficients: Pearson's correlation and Spearman's rho
9 Regression: Prediction with precision

Part 2 Significance testing
10 Samples from populations
11 Statistical significance for the correlation coefficient: Practical introduction to
statistical inference
12 Standard error: Standard deviation of the means of samples
13 Related t-test: Comparing two samples of related/correlated/paired scores
14 Unrelated t-test: Comparing two samples of unrelated/
uncorrelated/independent scores
16 Confidence intervals
17 Effect size in statistical analysis: Do my findings matter?
18 Chi-square: Differences between samples of frequency data
19 Probability
20 One-tailed versus two-tailed significance testing
21 Ranking tests: Nonparametric statistics

Part 3 Introduction to analysis of variance
22 Variance ratio test: F-ratio to compare two variances
23 Analysis of variance (ANOVA): One-way unrelated or uncorrelated ANOVA
24 ANOVA for correlated scores or repeated measures
25 Two-way or factorial ANOVA for unrelated/uncorrelated scores: Two studies for
the price of one?
26 Multiple comparisons in ANOVA: A priori and post hoc tests
27 Mixed-design ANOVA: Related and unrelated variables together
28 Analysis of covariance (ANCOVA): Controlling for additional variables
29 Multivariate analysis of variance (MANOVA)
30 Discriminant (function) analysis - especially in MANOVA
31 Statistics and analysis of experiments

Part 4 More advanced correlational statistics
32 Partial correlation: Spurious correlation, third or confounding variables, suppressor
variables
33 Factor analysis: Simplifying complex data
34 Multiple regression and multiple correlation
35 Path analysis
36 Analysis of a questionnaire/survey project

37 Meta-analysis: Combining and exploring statistical findings from previous research
38 Reliability in scales and measurement: Consistency and agreement
39 Influence of moderator variables on relationships between two variables
40 Statistical power analysis: Getting the sample size right

Part 6 Advanced qualitative or nominal techniques
41 Log-linear methods: Analysis of complex contingency tables

groups
43 Binomial logistic regression
