This channel includes lecture and tutorial videos I have created on topics, tools, and techniques related to statistics, data analysis, human resource management, and their intersections. The vast majority of my tutorials use the programming language R to demonstrate data management, analysis, and visualization techniques. In general, my goal is to provide resources and tools that will help viewers find answers to important and interesting questions regarding human behavior.
I also embed many of the videos within my free eBook called "R for HR: An Introduction to Human Resource Analytics" (rforhr.com/). As of June 2024, the book is in version 0.1.7 and includes 74 chapters of conceptual content and R tutorials. I create these videos as a side project and outside of my day job, and thus if you reach out to me, I may not have time to respond in a timely manner or at all. That being said, if you want to try and reach me, please use this email: davidcaughlin@rforhr.com.

Mixed-Factorial ANOVA
In this conceptual video, I introduce the mixed-factorial analysis of variance (ANOVA), which is part of the ANOVA family analyses aimed at comparing means. A mixed-factorial ANOVA has at least one within-subjects predictor variable and at least one between-subjects predictor variable.
In the context of employee training evaluation, a mixed-factorial can be appropriate for evaluating a pre-test/post-test with control group design.
For an R tutorial where I demonstrate a statistically equivalent (but simpler) approach to analyzing data from a 2x2 mixed-factorial balanced design, please check out this video: ruclips.net/video/7xaDlTeNvYk/видео.htmlsi=Ly5yOJF4y5T_j_Vi

Confirmatory Factor Analysis
Просмотров 3,7 тыс.4 месяца назад
In this video, I provide an overview of confirmatory factor analysis (CFA), which is part of the structural equation modeling (SEM) family of analyses. CFA is useful for specifying a measurement model and for evaluating the measurement structure of, for example, a multi-item measure. I introduce the concepts of path diagrams, model identification, model fit indices and cutoffs, parameter estima...
Applying a Noncompensatory Approach to Selection Decisions Using the Angoff Method in R
Просмотров 1106 месяцев назад
In this tutorial, we learn how to use the Angoff Method (Angoff, 1971) to apply a noncompensatory approach to informing selection decisions. When a noncompensatory approach is applied, applicants cannot compensate for lower scores on one selection tool (e.g., procedure, assessment, test) with higher scores on other selection tools. When a selection tool has a multiple-choice format with correct...
Noncompensatory Approach to Selection Decisions & Angoff Method

In this video, we learn how the Angoff Method can be used to apply a noncompensatory approach to informing selection decisions. When a noncompensatory approach is applied, applicants cannot compensate for lower scores on one selection tool (e.g., procedure, assessment, test) with higher scores on other selection tools. When a selection tool has a multiple-choice format with correct and incorrec...
Introduction to Cross-Validation
Просмотров 2376 месяцев назад
In this video, we learn about fundamental concepts and methods related to cross-validation, where cross-validation can be used to evaluate a model's performance. Further, we distinguish between statistical cross-validation methods (e.g., adjusted R-squared, squared cross-validity, cross validity) and empirical cross-validation methods (e.g., holdout method, k-fold cross-validation, leave-one-ou...
Compensatory Approach to Selection Decisions & Multiple Linear Regression
Просмотров 2096 месяцев назад
In this video, I explain how regression coefficient estimates from a multiple linear regression model can be used to predict criterion scores. This video is meant to provide a foundation for understanding how, in an employee selection context, organizations can (a) estimate a multiple linear regression model based on data from a validation study sample for 2 selection tools (e.g., personality t...

When working with an organization's HR or people data, we should pause regularly to ask ourselves: "Just because we can, should we?" In this video, we will consider the importance of identifying legal and ethical issues in HR analytics.

Judgment, Decision Making, & Bias | HR Analytics

Acquiring, managing, analyzing, and interpreting HR data are inherently subjective processes. Accordingly, it is important to understand and recognize how human judgment, decision making, and bias may affect these processes.
Language Considerations | HR Analytics

When interpreting HR analytics findings, particularly statistical findings, it is important to consider the type of language we use and to balance confidence with uncertainty.
Introduction to R

R is an open-source and freely available statistical programming language and environment that can be used for data management, analysis, and visualization. In this video, we will learn the basics about R and RStudio, where the latter is an integrated development environment (IDE) for R. For more information, check out: rforhr.com/overviewR.html
Internal Consistency Reliability
Просмотров 10 тыс.2 года назад
When we work with multi-item measures multi-item measures, we often estimate internal consistency reliability can be defined as “a reliability estimate based on intercorrelation (i.e., homogeneity) among items on a test, with [Cronbach’s] alpha being a prime example” (Schultz and Whitney 2005). In other words, internal consistency reliability tells us how consistent scores on different items (e...
One-Way ANOVA
Просмотров 4482 года назад
Analysis of variance (ANOVA) is part of a family of analyses aimed at comparing means, which includes one-way ANOVA, repeated-measures ANOVA, factorial ANOVA, and mixed-factorial ANOVA. In general, an ANOVA is used to compare three or more means; however, it can be used to compare two means on a single factor - but you might as well just use an independent-samples t-test if this is the case. Th...
