Continuing Professional Development Workshops

The aim of the workshops is to provide clients with basic statistical tools for inputting, describing and analysing data. The workshops are predominantly computer based using software packages such as Minitab, MS Excel, NVivo, R and SPSS.  The workshops are designed for clients with no prior knowledge of statistics and mathematical theory is kept to a minimum.  The workshops can be adapted to suit the requirements of the client.  Requests for other workshops may be made to the sean.lacey@cit.ie at any time.

 

Non-laboratory based

1.            Statistics for Research

Statistics fills the crucial gap between information and knowledge.  Society cannot be run effectively based on hunches or trial and error.  In research much depends on the correct analysis of numerical information.  Decisions based on data will provide better results than those based on intuition or gut feelings.

One of the major problems any researcher faces is reducing complex situations to manageable formats to describe, explain or model them.  This is where statistics comes in.

This workshop highlights which statistics to use, why to use those statistics, and when to use them.  Through using appropriate statistics, you will be able to make sense of the data you have collected so that you can tell your research story coherently and with justification.

 

2.            Research Questionnaire Design

This course introduces the basic elements of research questionnaire design.  The outline of the course is as follows:

  • Steps involved in designing a successful questionnaire;
  • Qualities of good questions;
  • Questionnaire length and wording;
  • Discussion on how questionnaires can be analysed using various statistical packages – e.g., SPSS, NVivo etc.

 

R and SPSS laboratory based

 

3.            Introduction to Data Analysis

This course provides an introduction to R and/or SPSS.  The outline of the course is as follows:

  • A basic introduction to statistics.  It is important before using R/SPSS that some basic statistical terminology is understood (terminology will be kept to a minimum);
  • Demonstration on how to set up a R/SPSS file;
  • Conclude with compiling some descriptive statistics (both numerical and graphical) for various data types.

 

4.            Statistical Inference

This course provides a look into the world of hypothesis testing with R and/or SPSS.  Basic knowledge of R/SPSS is assumed.  The outline of the course is as follows:

  • Explanation to the idea behind hypothesis testing (theory kept to a minimum);
  • Worked examples of testing for normality/differences/relationships with various types of data;
  • How to report on statistical results.

 

5.            Multi-Variable Data Analysis

This course will build on Statistical Inference.  The course will focus on:

  • How to line up and analyse various data sets properly in both a parametric and non-parametric way;
  • In the case of non-parametric data, the course will look at suitable transformations to use prior to the use of parametric tests;
  • One-way Analysis of Variance (ANOVA) with suitable posthoc testing;
  • Between subjects factorial experiments;
  • Within subjects factorial experiments;
  • Mixed factorial experiments.

 

6.            Multiple Regression

Correlation analysis is used to find out if there is a statistically significant relationship between TWO variables.  Linear regression analysis is used to make predictions based on the relationship that exists between two variables.  However, most things are too complicated to “model” them with just two variables. Multiple Regression is needed.  Multiple regression is a statistical technique that allows us to predict a score on one variable based on the scores on several other variables.  This course covers:

  • Scatterplots and partial regression plots;
  • Correlation and regression analysis;
  • Test for homoscedasticity;
  • How detect for multicollinearity and outliers;
  • How to check that the residuals (errors) are approximately normally distributed;
  • How to interpret regression equations and how to use them to make predictions.

 

7.            Time Series Analysis

This course will provide the necessary tools to develop and critically evaluate time series models.  The forecasting function of these models is presented and evaluated, enabling the ability to create short and medium term forecasting models.  A basic understanding of time series analysis is assumed.  The following topics will be introduced:

  • Decomposition (trend, periodicity, seasonality, white noise);
  • Smoothing techniques;
  • Autoregressive (AR), Moving Average (MA) and mixed (ARMA) models;
  • Forecast Error and Confidence Intervals.

 

8.            Multivariate Data Analysis

Exploratory Factor Analysis (EFA) is a statistical approach for determining the correlation among the variables in a dataset. This type of analysis provides a factor structure (a grouping of variables based on strong correlations). In general, an EFA prepares the variables to be used for cleaner structural equation modeling. An EFA should always be conducted for new datasets. The beauty of an EFA over a CFA (confirmatory) is that no a priori theory about which items belong to which constructs is applied. This means the EFA will be able to spot problematic variables.  This workshop will focus on:

  • Data screening;
  • Factoring methods;
  • Appropriateness of data;
  • Communalties;
  • Factor structure;
  • Convergent and discriminant validity;
  • Reliability;
  • Common EFA problems.

 

Minitab laboratory based

9.            Introduction to Data Analysis

Part I of this workshop provides an introduction to Minitab.  The outline is as follows:

  • A basic introduction to statistics.  It is important before using Minitab that some basic statistical terminology is understood (terminology will be kept to a minimum);
  • Demonstration on how to set up a Minitab file;
  • Conclude with compiling some descriptive statistics (both numerical and graphical) for various data types.

Part II of the workshop provides a look into the world of hypothesis testing with Minitab.  The outline is as follows:

  • Explanation to the idea behind hypothesis testing (theory kept to a minimum);
  • Worked examples of testing for normality/differences/relationships with various types of data;
  • How to report on statistical results.

 

10.          ANOVA and Design of Experiments (DOE)

Part I of this workshop will look at analysing data using Analysis of Variance:

  • Completely randomised designs;
  • Randomised block designs;
  • Factorial designs.

Part II will introduce Design of Experiments (DOE).  DOE help investigate the effects of input variables (factors) on an output variable (response) at the same time.  These experiments consist of a series of runs, or tests, in which purposeful changes are made to the input variables.  Data are collected at each run.  DOE is used to identify the process conditions and product components that affect quality, and then determine the factor settings that optimise results. Part II of the workshop covers:

  • DOE Language and Concepts;
  • Creating a factorial design;
  • View a design and enter data in the worksheet;
  • Analyse a design and interpret the results;
  • Use a stored model to create factorial plots and predict a response.

 

11.          Process Capability Analysis

A process capability analysis is performed to determine if a process is statistically capable. Based on the results of the capability study, an estimate to the number of defective components the process would produce can be determined.

  • Run and Pareto chart;
  • Variables control charts: XBar, R, S, XBar-R, XBar-S, I, MR, I-MR, I-MR-R/S, zone, Z-MR;
  • Historical/shift-in-process charts;
  • Box-Cox and Johnson transformations;
  • Process capability for multiple variables;
  • Tolerance intervals;
  • Acceptance sampling and OC curves.

 

12.          Correlation, Regression and Multivariate Analysis

Correlation analysis is used to find out if there is a statistically significant relationship between TWO variables.  Linear regression analysis is used to make predictions based on the relationship that exists between two variables.  However, most things are too complicated to “model” them with just two variables. Multiple Regression is needed.  Multiple regression is a statistical technique that allows us to predict a score on one variable based on the scores on several other variables.  This course covers:
