An easy intro to key statistical concepts. Learn about data visualization and outlier detection. Demystify statistical significance testing. An excellent introductory module and a solid basis for all other modules.
Fundamental Statistical Tools for Research
Course Details
Upon completion of this module, participants will be able to:
 Understand the difference between descriptive & inferential statistics
 Appreciate the value of exploratory methods in preliminary data analysis & design of experiments «DOE»
 Explore, characterize and identify problems and trends in data using plots
 Use descriptive statistics to summarize data
 Understand the concepts of hypothesis testing: risks, pvalue, confidence intervals, power
 Identify the appropriate statistical test based on the study objective
 Understand the importance of sample size calculations and the required input parameters
 Analyze data more quickly and more accurately
 Interpret results reliably and confidently
This module is aimed at anyone who works with data and who must make decisions based on them.
This module introduces key concepts in statistics and data analysis. It assumes that participants either have no previous knowledge of statistics or that they have not used statistics for a long time.
 The importance of statistics
 Descriptive statistics
 Importance of identifying the type & role of variables
 Visualising and summarising data distributions
 Frequency tables for categorical variables
 Pearson's correlation coefficient for continuous variables
 Plotting Data: Histograms, Scatter, boxplots, bar charts
 What is statistical inference?
 Hypothesis testing principles: Null and alternative hyposhesis, one vs. twotailed tests
 Risk involved in significance testing
 Test statistics: Ttest, Ftests...
 Observed significance level or "pvalue"
 Statistical significance & decision rules
 The importance of sample size calculations

Excellent overview of statistics. I feel like I was able to obtain a strong understanding of the basics and will now be able to build on that. Highly recommended!

Excellent overview of the most important concepts in statistics. The boxplot graphical tool was excellent in helping to determine if data can be considered independent, normally distributed samples so that standard statistical analysis can be conducted. The scope of statistical tests, use of the pvalue, and how to minimize risks were all clearly explained. Finally, how to interpret confidence intervals and the equivalence between confidence intervals and hypothesis testing helped me to gain more confidence in my analyses.

I started with a minimal knowledge of statistics and statistical methods and tests. This course brought me right up to speed with my colleagues. The concepts were clearly explained and there were several examples of each concept. Overall, an enjoyable and informative course.

Overall the course was great. The teacher was very thorough in all aspects of the class. The class was well taught, the teacher asked questions to make sure we all understood, got class participation and incorporated in real examples from each participant.
