This document is a completed Week 1 assignment for BST 322, Introduction to Biomedical Statistics, at National University. It was submitted by Mario Martinez.
This assignment is intended for students enrolled in the course to demonstrate their understanding of foundational statistical concepts covered in the first week of study. It serves as a graded assessment of their ability to differentiate between variables and constants, identify independent and dependent variables in research questions, classify variables by type (discrete/continuous, nominal/ordinal/interval/ratio), and perform basic data analysis using StatCrunch.
This assignment does *not* provide instruction on these concepts; it showcases an application of them. It also doesn’t offer a comprehensive guide to StatCrunch – it simply presents results obtained from using the software.
The full assignment includes: solutions to questions identifying variables and constants, independent and dependent variables, discrete and continuous variables, and nominal/ordinal/interval/ratio scales. It also contains a frequency distribution table and summary statistics (n, mean, mode, skewness, kurtosis) generated in StatCrunch for a given dataset, along with a graphic representation of the data and an analysis of its distribution. Finally, it includes bar and pie charts created in StatCrunch from a separate dataset related to marital status.
