Bio

I earned my master’s degree in psychology from California State University, Northridge, where I received the Donald Butler Quantitative Research Award for excellence in quantitative methodology.

My name is Jesus, and I specialize in statistics, psychometrics, and quantitative research methods in the social sciences. I earned my master’s degree in psychology from California State University, Northridge, where I received the Donald Butler Quantitative Research Award for excellence in quantitative methodology.

I am a current PhD student in quantitative psychology, and my work centers around psychometrics and statistics, including Item Response Theory (IRT) and Classical Test Theory (CTT), as well as factor analysis, missing data techniques, robust statistics, and nonparametric methods. I focus on helping students understand both the conceptual foundations and practical application of these approaches so they can use them confidently in their own research.

I primarily work in R and am also highly experienced with SPSS. Whether you’re working on coursework, thesis analyses, or independent research, I aim to make quantitative methods approachable, intuitive, and manageable. I typically assist students in graduate programs going through relevant coursework, or those working on larger projects (e.g., thesis/dissertation), although I am happy to work with interested undergraduate students as well!

Knowledgable and personable!

Jesus is someone who can make the dreary of a highly complex subject like quantitative methodology relatable to anyone. He has a wide depth of knowlege and he presents the information in a way that is both informative and even enjoyable. Before I found him I wondered how I was going to complete my advanced stats doctoral level course work but after working with him I feel compelled to view stats in a whole new way .. He makes the learning fun (which is the mark of an exeptional tutor) ! I honeslty can not speak highly enough of my time spent learning with him!

Really prepared and great at explaining concepts

Jesus was always prepared and ready to dive into the content - he did a fantastic job explaining concepts, while being patient and thoughtful. He's great at one-on-one tutoring!

Knowledgeable and Patient Tutor

Jesus was extremely patient and proved to be an expert in all things SPSS and data analysis. I would / am going to seek both his mentorship and assistance in the future. Thank you Jesus!

Rolando, 1 lesson with Jesus

Very knowledgeable and very patient!

I was stuck on an issue with multiple imputation for a three-level mixed regression model for my PhD dissertation, and Jesus was a life-saver. He was patient as I talked through my data and asked him questions, and he spent time carefully understanding the issue before recommending a course of action. I feel super confident moving forward in my analysis now, which is a massive relief. It can be hard asking for help, but if you're considering reaching out to Jesus, do it! I highly recommend Jesus for help with R/Rstudio, mixed/hierarchical/multilevel models, and multiple imputation (including the MICE package in R).

Best tutor I could have asked for!

Jesus has been an incredible tutor, going above and beyond by reading articles related to my analysis method outside of our sessions to better support my learning. His deep knowledge of missing data and statistics, combined with his patience in teaching R, has been invaluable in tackling advanced methods for my PhD. Don’t wait to book with him! No matter your current level of knowledge he can help :)

SPSS and Data Analysis

Jesus was the absolutely best tutor that I have had thus far!!!! He was patient, and understanding and allowed me to go at my own pace so that I could truly understand. Thank you for your patience and understanding! I will be back soon! 100%

integration

He helps integrate statistics, the professor's confusing comments and sometimes contradictory directions in the process while helping explain the process. I appreciate the feedback and insights.

Expert in Stats and R!

Jesus was extremely helpful with a complicated missing data issue I was working through for my PhD dissertation. There are very few people with the knowledge and skills to work with real world data that Jesus has. He is also amazing with R and R Studio.

Caitlyn, 17 lessons with Jesus

Patient and helpful

Jesus saved me during my advanced stats graduate class. He's incredibly patient and calm and works through the problem with you until you understand it. He truly wants to help his students, and it shows. Thank you, Jesus!
