Overview For your final project, you will use R to solve problems about probability distributions. Specifically, you will make use of the d, p, q, and r functions built into R for working with probability distributions. In most cases, you will need to determine the type of probability distribution that is described and use R […]

Apply the fundamental R programming concepts, including vectors, data frames, subsetting, and basic visualization, to analyze a dataset of housing values in the suburbs of Boston. Uses an external CSV file that contains some missing values. A key part of the task will be identifying and handling these data issues before performing your analysis. Download […]

Overview In this project, you will use R to solve counting and probability problems. To gain the most benefit from this project, avoid calculating numeric values and entering them into R. Instead, use R to do all necessary calculations. This project analyzes trends in U.S. housing prices and affordability using open-source data. The goal is […]
