In biological research, particularly in museum-based studies, statistics plays a central role in transforming raw observations into meaningful scientific knowledge. Museum collections and field data provide rich sources of information, ranging from species distributions and ecological patterns to variation in morphological traits across populations. Statistical methods enable researchers to organize, analyze, and interpret these data, uncovering patterns and relationships that would otherwise remain hidden.
This Shiny application is designed as an interactive learning and exploration tool that demonstrates how statistical thinking is applied in real biological and museum research. Through hands-on visualizations and guided examples, users can develop a deeper intuition for key statistical concepts and see how they directly support scientific discovery in the biological sciences.

Build your understanding of essential statistical measures—sample size, mean, standard deviation, minimum, maximum, mode, median, and range—using real quantitative data.
Start by exploring the Module 01 PDF for a quick overview or download here. Then strengthen your learning with the interactive app below using provided or your own data!
Explore graphical representations of quantitative data to understand their distribution, shape, and variability.
Build your understanding of essential statistical measures for qualitative (categorical) data, including frequencies and proportions (percentages).
Develop your understanding of linear regression by learning how relationships between variables are modeled, interpreted, and used for prediction.
Learn how the slope, intercept, and R² describe and evaluate these relationships.
Learn how to draw conclusions about population means using sample data.
This module includes three sections: one mean, two means, and paired means.
A researcher plans to take a random sample of size n students to do a survey about their experience on the SAT math test. The researcher makes a confidence interval for the SAT math scores of the students in her study and compares it to the mean of 528 for the population of all seniors in the U.S. These data are about College Bound high school graduates in the year of 2019 who participated in the SAT Program. Students are counted only once, no matter how often they tested, and only their latest scores and most recent SAT Questionnaire responses are summarized.
Click the analyze button to create 50 samples to see their confidence intervals and histograms.
Population difference in means is -12, Standard deviation for the difference in population means is 163.38
Click the analyze button to draw a new sample from the population
Learn how to draw conclusions about population proportions using sample data.
This module includes two sections: one proportion and two proportions.
This module introduces the fundamentals of probability through simulation, allowing users to explore random events,
compare empirical and theoretical results, and understand key probability rules.
