STAT100 - penguin populations in Antarctica Anvers region Assignment

Assignment Task 

Overview

Scientists are very interested in monitoring changes in penguin populations in Antarctica, as recent research has shown some vulnerabilities in these populations.

A study has been conducted which looks at a number of species of penguins in Antarctica in the Anvers region and some characteristics of individuals within these species. A sample of this data has been provided to you (note that this sample is different for all students), containing 80 individuals. The following columns are included in the dataset:

• Sample Number: An identification number for each individual
• Species: 3 different species with common names of Adelie, Chinstrap and Gentoo
• Sex: MALE or FEMALE
• CulmenLength: A measure of the length of the culmen (in mm)
• FlipperLength: A measure of the length of the left flipper (in mm)

You will explore and analyse the data using R, and present your findings in a written report. Your goal is to use appropriate statistical inference methods to answer the following three research questions:

1. Is there evidence that one species of penguins is more or less prevalent in the Anvers region?
2. Do males have significantly larger culmen length than females?
3. Is there a significant linear relationship between culmen length and flipper length for Chinstrap penguins?

You may need to refer to the R glossary on the Moodle site for guidance on how to subset the data to look at only the Chinstrap penguins

• Produce a plot of the data to explore the research question:
• Ensure that each plot has a title/caption
• Refer to and describe what the plot indicates in relation to the research question in your report - ie what does the plot suggest?
• Identify the relevant statistical (hypothesis) test and conduct the appropriate analysis to answer the research question by:
• Following the steps of hypothesis testing explicitly
• In addition to stating the hypotheses in words, provide the corresponding mathematical notation, where appropriate
• State and check the necessary conditions for each test, referring to relevant plots
• Include relevant confidence intervals.
• Calculate and present all relevant test statistics and associated output using RStudio. When including RStudio output in this section please follow presentation guidelines.
• Text output from RStudio should be presented in a table, with an appropriate caption above the table
• Plots should be presented as a figure, with an appropriate caption below the figure
• Give a concise and informative interpretation of your findings by:
• Referring to your stated hypotheses as well as any relevant calculated values from your RStudio output including summary statistics, test statistics, degrees of freedom, p-values and confidence
• Relating it to the context of the research question

Presentation 

Produce a report in your choice of word processing software (eg Microsoft Word or Google Docs) that includes all of the above information. Ensure that your report includes a title, is logically structured, and the sections within each question are clearly indicated with headings or itemised. Include all the R code that you used at the end of each research question – please show all code in a separate font (a fixed width font like Courier New is ideal). Each plot should have a label and a caption immediately below (eg Figure 1: Boxplot of …), and each table should have a label and caption immediately above. Save your report as a single pdf file, and submit that file on Moodle.
