This repository contains some of the projects and assignments that I have completed, either individually or as part of a group. The details are as follows:
Qualtrics Analysis: Automated graph generation and data visualization processes for the annual report of the MSU Extension Water Quality Project
STAT512 Final Report: Analysis of the data collected from research "Over-Reporting in Handwashing Self-Reports: Potential Explanatory Factors and Alternative Measurements"
Data Analysis 1: This dataset, sourced from Wetlaufer, Hendrikx, and Marshall (2016), examines the relationship between snow characteristics (snow density in kg/m³ or snow depth in mm) and various predictor variables. The focus of the analysis is on snow presence or absence at each sampling location (SnowPresence). To measure snow characteristics, the dataset includes key environmental predictors: elev: Elevation (in meters) Land: Forest cover, where 0 = unforested and 10 = forested rad: Potential Solar Radiation (in Wh/m²) curvature: Describes the curvature of the terrain (detailed explanation here) aspect: Orientation of the slope (in degrees, ranging from 0 to 360) angle: Angle of slope (in degrees, with 0 representing a flat surface) Additionally, the dataset takes into account the strata variable, which played a significant role in the data collection process, helping to ensure the sample’s representativeness. These fixed effect predictors are used to assess their influence on snow presence.
Data Analysis 2: This data analysis is part of a group project. The data aimed at investigating factors related to egg-laying and parental care in archosaurs, a group of reptiles that includes both crocodilians and birds. The study includes data from over 400 species of archosaurs and measures the following variables: BodyMass: Body mass of the species (in kg) ClutchVolume: Volume of eggs in a single clutch (in mm³) CareSex: Sex of the primary parent responsible for caring for the eggs (B: biparental, M: maternal, P: paternal) HigherTaxon: Higher taxonomic classification of the archosaur (A: Avian, C: Crocodilian) The goal of the analysis is to estimate a model for ClutchVolume based on these predictor variables, providing insights into the factors influencing egg-laying and parental care behavior in archosaurs.
