Getting Started with StatisticTeach1

Introduction

StatisticTeach1 is an interactive Shiny application for teaching and learning basic concepts in statistics and probability. It provides visual, hands-on exploration of:

Descriptive statistics for continuous and categorical variables
Frequency tables
Probability distributions (discrete and continuous)

Installation

install.packages("StatisticTeach1")

Launching the App

library(StatisticTeach1)
runStatisticTeach1()

This opens the Shiny interface in your default web browser.

Standalone Functions

Two utility functions are also available outside the app:
