Course Breakdown

 

Session 1: Introduction to statistics and working with quantitative data

Aim: Topics:

To learn about the role of statistics in research; to understand key concepts for working with quantitative data; to get started with SPSS.                               

 

Introduction

  • Role of statistics in research
  • The Scientific Method
  • Data types / levels of measurement
  • Descriptive vs. inferential statistics and key mathematical concepts
  • Getting started with SPSS

Session 2: Research Methodologies

Aim: Topics:

To gain an understanding of core descriptive statistics; to use SPSS to summarise and visualize data effectively and appropriately.

 

 

 

Measures of central tendency

  • Arithmetic mean, mode, median
  • Quartiles and percentiles
  • Weighted mean, quadratic mean, harmonic mean

Measures of dispersion

  • Range and interquartile range (IQR)
  • Variance and standard deviation (SD)
  • An introduction to degrees of freedom (df): Why do we divide by (n-1)?
  • Standard error (SE) and confidence intervals

Frequency distributions

  • Introducing distributions
  • Frequency tables and cumulative frequency
  • Skewness and kurtosis

Graphical representation of data using SPSS

  • Bar charts vs. pie charts
  • Histograms
  • Boxplots
  • Line charts
  • Scatter plots

Session 3: Probability

Aim: Topics:

To explore the concept of probability as the basis of inferential statistics; to explore probability distributions and understand the importance of the normal distribution.

 

What is probability?

Probability distributions

  • Uniform distribution, Binomial distribution, Poisson distribution
  • Normal distribution (the Bell Curve)
  • Probability density functions (PDFs)
  • Cumulative distribution functions (CDFs)

Central Limit Theorem

Session 4: Z-scores and the path to hypothesis testing

Aim: Topics:

To gain an understanding of the foundations of hypothesis testing; to explore how probability underpins the concept of statistical significance.

 

Designing statistical hypotheses

  • Understanding null and alternative hypotheses

From z-scores to p-values

  • Standardisation and statistical significance

Hypothesis testing: probability, thresholds and interpreting results

Session 5: Detecting differences - choosing the right statistical test!

Aim: Topics:

To learn how to choose the right statistical test for different types of research questions and designs; to practice running statistical tests using SPSS.

 

 

 

The difference between parametric and non-parametric tests (why it is important!)

Test assumptions

  • Normality, homogeneity or variance, sphericity

T-tests

  • One sample
  • Independent samples
  • Paired samples

Wilcoxon signed-rank test and Mann-Whitney U Test

  • ANOVA One-way ANOVA
  • Two-way ANOVA
  • Repeated measures ANOVA

  • Levene’s test for homogeneity of variance
  • Mauchly’s test of sphericity

Session 6: Associations - correlation

Aim: Topics:

To learn to use statistics to assess relationships between variables.
