Food Science Data Analysis - Basic Statistical Methods and Visualization Techniques

Learn fundamental data analysis techniques specifically tailored for food science applications through this comprehensive lecture series. Master descriptive statistics and data visualization using ggplot2 to effectively present food science datasets. Explore Principal Component Analysis (PCA) concepts, estimation methods, centering and scaling procedures, variance explanation, and biplot interpretation for dimensionality reduction in food data. Understand correlation and covariance principles as foundational statistical concepts and their relationship to PCA. Delve into normal distribution theory, confidence intervals, and t-tests for hypothesis testing in food science research. Analyze categorical data using chi-square tests and work with binomial distributions for binary outcomes common in food quality assessments. Calculate statistical power for binomial distributions and t-test scenarios to design robust food science experiments. Apply one-way ANOVA techniques and understand contrasts in ANOVA models for comparing multiple food treatments or conditions. Implement linear regression with single predictor variables and learn least squares estimation methods for model parameter determination. Gain practical experience with R Markdown for reproducible research documentation and explore jamovi as an alternative statistical software platform. Access specialized food science datasets through the accompanying R package to practice analysis techniques on real-world examples including coffee temperature panel data with multiple assessors and replicates.
