Biostats Made Simple Series

Home / Research / Research Learning Series / Biostats Made Simple Series

The Biostats Made Simple series is led by Dr. Christine Ramdin. Each lecture covers fundamental biostatistics concepts that every resident and/or early career researcher should know. The series provides learners with the fundamental knowledge regarding: descriptive and inferential statistics, chi-square tests, p-values, confidence intervals, regression analyses, power and sample size, interrater reliability, and more.

    This is the first webinar of "season two" of our Biostats Made Simple series with Dr. Christine Ramdin! In this session, Dr. Ramdin will recap key principles learned in the prior season and move on to more hands-on and practical applications of more advanced concepts such as creating visuals in SPSS, sensitivity/specificity, sample size and power calculations, regression analysis, effect size, and more.

  • Research Learning Series (RLS) - Biostats Made Simple: Session 10

    May 23, 2025

    This session concludes this series of Biostats Made Simple. It involves a panelist of 3 guest speakers (journal editors) who comment on the most common statistical mistakes made by junior/early career investigators in their manuscript submissions.

  • Research Learning Series (RLS) - Biostats Made Simple: Session 9

    Apr 11, 2025

    In this session, we conduct a review of the previous 8 sessions and provide examples of databases available in SPSS format for analysis. We also introduce the National Hospital Ambulatory Care Survey (NHAMCS) database, how to conduct basic analyses using this database, and how to query the database to conduct more complex analyses.

  • Research Learning Series (RLS) - Biostats Made Simple: Session 8

    Mar 13, 2025

    This session focuses on reviewing the different types of regression models specifically for dependent variables of nominal, ordinal, and count data, how to conduct them using SPSS. We review best practices for reporting regression models such as evaluating model fit and interpreting results.

  • Research Learning Series (RLS) - Biostats Made Simple: Session 7

    Jan 27, 2025

    Biostats Made Simple Session 7 introduces the utilization of regression models in SPSS. We focus on when to use and how to conduct regression/association analyses for models that have continuous/scalar dependent variables.

  • Research Learning Series (RLS) - Biostats Made Simple: Session 6

    Jan 8, 2025

    In this session, we review the statistical tests used to compare 3 or more groups of continuous/scalar data that can be linked. We conduct examples utilizing the repeated measures ANOVA and Friedman test using SPSS.

  • Research Learning Series (RLS) - Biostats Made Simple: Session 5

    Jan 8, 2025

    In session 5, we review what tests to use when you would like to conduct comparisons of 3 or more groups of continuous/scalar data that are unmatched. We review how to utilize the ANOVA and Kruskal-Wallis tests using SPSS.

  • Research Learning Series (RLS) - Biostats Made Simple: Session 4

    Nov 4, 2024

    This session reviews how to determine when to use the paired t-test and Wilcoxon signed rank test. We conduct examples utilizing both tests using SPSS.

  • Research Learning Series (RLS) - Biostats Made Simple: Session 3

    Oct 18, 2024

    In this session, we introduce how to use SPSS and demonstrate how to conduct Shapiro Wilk’s test in SPSS. We also provide examples, explain when to use, and demonstrate how to conduct the independent samples t-test or Mann Whitney U test in SPSS.

  • Research Learning Series (RLS) - Biostats Made Simple: Session 2

    Sep 17, 2024

    This session reviews the utilization of the Chi-Squared difference of proportions test and the Fisher’s exact test. We provide examples and how to conduct these tests using validated online calculators such as vassarstats and social statistics.

  • Research Learning Series (RLS) - Biostats Made Simple: Session 1

    Aug 7, 2024

    The first session of the series introduces descriptive statistics, how to conduct basic calculations in Excel, and how to create visuals in Excel. We also introduce the concept of utilizing the Shapiro Wilk’s test to determine data normality.
