FIT1006 ASSIGNMENT 2: DATA ANALYSIS

Purpose

In Assignment 1, we collected a dataset within the class. This task involves analysing that dataset.

Assessed Unit Learning Outcomes:

1. Perform and justify the use of appropriate descriptive and inferential statistical analyses such as standard deviation, t-tests, and Pearson's correlation coefficients

2. Communicate the results of statistical analysis effectively and accurately

3. Create graphics and tables for effective communication of the results of data analysis

4.   Analyse the factors that make statistics reliable, credible and trustworthy

Your task

You will write a written report of up to 2000 words, which will cover matters including:

Visualising the data in question.

Hypothesis testing.

Critically assessing the investigation that you have conducted.

Value

45% of your total marks for the unit

Word Limit

2000 words (excluding references and charts)

Due Date

Friday 05th of May 2023, 11:55 pm

Submission

Via Moodle Assignment Submission.

Turnitin will be used for similarity checking of all submissions.

Assessment Criteria

The assessment criteria is as given in Annex A.

Late Penalties

If you are late, then you lose 5% of the available marks for the assignment for each calendar day (or part of calendar day) you are late.

If you are 7 or more days late, then you will obtain a mark of zero for this assignment. It is possible to obtain an extension to this assignment deadline by way of the special consideration procedure, but only if you have extenuating circumstances.

A. Introduction

In Assignment 1, we collected a dataset within the class. This task involves analysing that dataset. You will write  a written report  of up to  2000 words, which will cover  matters including:

1.   Visualising the data in question.

2.    Hypothesis testing .

3.    Critically assessing the investigation that you have conducted.

This assignment is worth 45% of the overall mark for FIT1006.

B. When is my assessment due?

Your assessment is due on Friday the 5th  of May 2023 at  11:55pm . If you are late, then you lose 5% of the available marks for the assignment for each calendar day (or part of calendar day) you are late. If you are 7 or more days late, then you will obtain a mark of zero for this assignment. It is possible to obtain an extension to this assignment deadline by   way   of  the   special   consideration   procedure,   but   only   if  you   have   extenuating circumstances.

C. What am I required to do?

You  are  required  to  identify  an  issue  or  question  related  to  the  data  and  conduct  an statistical investigation. For this investigation you should prepare a written report of up to 2000 words (excluding references and images). This report should be in three parts:

A. Data visualisation and Descriptive Statistics. You should identify a topic of concern and   perform   descriptive   analysis   using   (i)   appropriate   summary statistics and (ii) visualisations of the data using appropriate charts . Your written text should explain these statistics and visualisations, including how they relate to your topic of concern.

B. Hypothesis testing. You should specify (i) at least one hypothesis in respect of your  topic  of  concern  (ii)  at  least  one null hypothesis and  (iii)  conduct  an evaluation of the said hypothesis using inferential statistics (including how the test was chosen, whether any data was excluded, and any other design decisions that  you  took). You must use  the  dataset  we  have  collected,  and  you may use additional datasets that you can find.

C. Critical Assessment. You should write a critical reflection as part of your report. This will discuss the strengths and limitations of your statistical study, and how you might build upon it in the future.

For this assignment, we will give you a individual dataset, which you must use. This will be the data collected by the class, however you will be given only a random subset of this (to  make  the  assignment  unique  to  you).  To  access  this,  please  download  the ZipFile on Moodle, and use the file associated with your student ID.

Important: A marking rubric is provided in Annex A. Please consider this carefully, as it is a guide to how you will be assessed and the weighting for each criterion.

D. What support will I be given with this assignment?

This  is  an  important  assignment  and  we  will  provide  support  to  assist  with  this .  In particular, we will provide:

Online material where you will be supported in learning the course.

•    Tutorials to develop your understanding of implementing the relevant statistical methods.

Individual consultations to  review  a  draft  of  your  assignment  (15  minute appointments: bring a draft, a calendar will be published on Moodle) .

E. Some Questions and Answers

1. Does the word count include diagrams and references.

The  word  count  excludes  references  and  diagrams.  However,  you  are  encouraged  to present  a  focussed  and  clear  report.  25%  of  the  marks  are  awarded  for  quality  of communication.

2. If I write a report that is less than 2000 words, will I receive a lower mark?

No. You are encouraged to write in a concise and focussed manner. 2000 words is a limit,

not a target.

3. What is the difference between a topic of concern and a hypothesis?

A topic of concern is a wider area of investigation, whilst a hypothesis is directly testable following an inferential statistical method (e.g. a t-test or an ANOVA).

4. Must I obtain a statistically significant result?

No. The idea is that you conduct an effective investigation, rather than obtain a particular result.  You   are   marked   on  completing  the   process   correctly   and  how   clearly  you communicate the outcome, as well as you critical reflection on the process and conduct of the experiment.

5. May I reuse material from Assignment 1 in this written report?

You  may  not  resubmit  text  from  your  written  commentary  in  Assignment  1  for  this assignment.  Nor may you reuse any material from any other course.

6. What happens if I write a report that is longer than 2000 words

If an  assignment  is  overlength,  then  your  marker  has  the  right  to  stop  reading  (and marking)  at  2000 words.  Furthermore, it is likely you will be penalised in  Criterion  4 (which relates to quality of communication).

7. May I use Generative AI?

Chat GPT is not going to help you with this assignment, but I have not expressly banned it.
