Analysis of Variance for Sensory & Consumer Tests – Beyond the Basics

The remote learning package consists of a live interactive lecture delivered online by one of the Qi Statistics team, together with workshops for you to complete in your own time (solutions and data sets provided), plus a pdf of the lecture notes and email support whilst you are completing the workshop after the course for up to 2 weeks. More than just a recorded webinar and as close to face-to-face training as it can be!

The training will be carried out using the modelling functionality in XLSTAT.

The course content is as follows:

• Analysis of Variance (ANOVA) Review
• Sensory Panel Data – should I use ANOVA or Mixed Models?
• Multiple Comparison Tests – Gains and Losses
• ANOVA assumptions – Do they matter?
• There are several different scales used for questions – which ones can be analysed using ANOVA?
• Testing demographic by product effects – Nested Models
• Incomplete Product Test Designs – Guidance for Analysis
  • What do Type1 , Type II, Type III Sums of Squares measure?
  • Messy Data – Illustrated using Shelf Life Tests
• Repeated Measures- when and how to use the models

The remote training package includes the one-hour lecture, plus time for questions/discussion and a set of exercises with worked solutions (explanation of statistics and interpretation with screen shots).

Length of Session:

Approx 1.5hr workshop

Pre-Requisites:

A basic understanding of statistics is assumed i.e. knowledge of statistical terminology and summary measures such as mean, variance, standard deviations.
