Principles of Analysis : Descriptive and Inferential Statistics
PRINCIPLES OF ANALYSIS: DESCRIPTIVE AND INFERENTIAL STATISTICS
INTRODUCTION
Effective data analysis is essential for decision-making, reporting, and quality control in any professional environment. Understanding descriptive and inferential statistics helps individuals summarize data, identify trends, and make informed predictions based on statistical evidence.
This Principles of Analysis session provides a high-level introduction to essential statistical concepts, including data measurement, summary statistics, inferential techniques, and data quality considerations. The session is delivered in a discussion-based format, with no group activities, offering an overview before more detailed sessions on specialized topics.
This John Varlow | Training and Consultancy session will cover:
✔ Understanding levels of measurement, central tendency, and dispersion
✔ Exploring prevalence and incidence rates in data reporting
✔ Effective data presentation and visualization methods
✔ Introduction to inferential statistics, statistical tests, P-values, and confidence limits
✔ The importance of data quality in statistical analysis
✔ Basic principles of statistical process control (SPC)
SESSION OBJECTIVES
By the end of this 3-hour session, participants will be able to:
✔ Understand descriptive statistics and their role in data analysis
✔ Recognize key statistical measures such as mean, median, variance, and standard deviation
✔ Differentiate between prevalence and incidence rates and their significance in data analysis
✔ Apply best practices for data presentation and visualization
✔ Gain a foundational understanding of inferential statistics and hypothesis testing
✔ Appreciate the importance of data quality and its impact on decision-making
✔ Be introduced to statistical process control (SPC) techniques
TRAINING METHODOLOGY
This session is interactive and discussion-based, designed to provide a clear conceptual foundation in statistical analysis. Unlike other workshops, there are no group activities—instead, the focus is on theoretical understanding, real-world applications, and structured discussions.
✔ Clear explanations of fundamental statistical concepts
✔ Real-world examples to illustrate data analysis in practice
✔ Opportunities for discussion and Q&A to reinforce learning
✔ Preview of more advanced statistical topics covered in future sessions
This approach ensures that participants gain a solid statistical foundation while preparing them for more detailed sessions on specific analysis techniques.
