Introductory Statistics 161.120 Assignment 1: Sampling Analysis Report

This assignment solution addresses sampling methods and exploratory data analysis using a sample of kuku mussels. The solution begins with a description of the sampling methodology, specifically simple random sampling, and discusses alternative methods like quota or stratified sampling. The analysis then explores the sample data, examining the representation of gender and kuku grades using percentages and a clustered bar chart. It further delves into descriptive analysis of kuku lengths, presenting a histogram, frequency distribution table, and summary statistics. Five-number summaries and side-by-side box plots are used to compare lengths based on gender and grade. The assignment concludes with an analysis of the descriptive findings, highlighting differences in length by grade and gender and noting that female kukus were slightly smaller than males. The analysis emphasizes that the findings are specific to the population of kuku mussels in the Marlborough Sounds and cannot be generalized.
