ATHK1001 Assignment 1
1. Where do I submit my assignment? If you go to the ATHK1001 Canvas website and
look under “Modules” then “Assessments” you will see a link for “Assignment 1
submission/view”. If you click on this link you will see the submission instructions and the
link to Turnitin. The instructions are similar to those you will see for other classes.
DO NOT TRY TO SUBMIT YOUR ASSIGNMENT BY E-MAILING IT TO A TUTOR OR
INSTRUCTOR. We cannot accept submissions directly; they must be made via Canvas.
2. What file format should I use? The submission link will only accept PDF files.
3. When should I submit my assignment? By the 11:59pm Friday 31/3/2023 (Australian
Standard Time), but try to submit sometime before. Avoid leaving it to last minute. With any
computer system delays, problems, or confusion can occur, especially if this is the first time
you have submitted to Canvas. Computer problems are not considered grounds for an
extension unless they affect all students.
4. How do I know I have successfully submitted my assignment in Canvas? Once you
have clicked submit, you will be brought to the next page. If you scroll to the end of this
page, you will see submission details. If the submission has been made there will be a tick
next to the word Submitted! The submission time will be listed, and importantly, you can
click on the file you submitted to check the correct file was submitted. If you need to
resubmit, you can return to the top of the page and click “new attempt”.
5. Should I upload an Excel file? No. Given that you will most likely be doing your
calculations in Excel I can understand why this question is asked. However, the assignment
description says you should answer the questions using complete sentences, so you should
take what you calculate from Excel and use it to answer questions in the document you will
submit. You do not need to show your calculations, just the values you calculate in order to
answer the questions. For Question 7, where you are asked to create a graph, you should copy
the graph created into your submission. Note that you are not required to use excel to do your
analysis, if you prefer to use a different program to do your analysis then that is fine.
6. Should I put my name on my assignment? No, Canvas will keep track of who the
submission is by. We mark your assignments anonymously so you should not break that
anonymity by putting your name on your assignment.

7. Should I repeat the questions when giving my answer? No, just give the question
number. We have the assignment, so we don’t need the question to be repeated. Repeating
questions will reduce the number of words you have available within the word limit, and lead
to Turnitin giving us a plagiarism warning.
8. Could I use a graph, table, or point form to present statistics? All questions on the
assignment must be answered using prose and full sentences, except for the graph requested
in Question 7. A sentence must include a verb. This is because the results of statistical
analysis are usually reported in sentences, and we need consistency given that everyone has
the same word limit.
9. What sort of graph can I use for Question 7? Line, bar and column graphs are all
acceptable for this graph. A column graph is probably most appropriate.
10. How can I make sure I will receive all the marks available for a question? It is
important to read the questions on the assignment carefully and note that there are often
different subparts. Receiving full marks will require you to respond correctly to all parts of
the question. For example, Question 10 asks you to identify three possible problems with our
data collection. This question is worth 12 marks in total but is really three 4-mark questions,
with 4 marks allocated to each possible problem you identify.
For some questions there is only one correct answer (e.g., when we ask you to calculate a
mean) but other questions may have multiple good answers (e.g., when we ask what you
think the data tells us in Question 12).
11. How many decimal places should I use when reporting results? The general answer is
the number you think is most informative, so present descriptive data with sufficient decimal
places for critical differences to be observable, but not more. The convention is to use the
same number of significant digits as are present I the data, as described in the Assignment.
12. If I find a very small p-value, how do I report it? For p-values you would generally
report them to at least three or four decimal places, but sometimes those decimal places are
all zero. One convention is that if the p-value is zero to at least four decimal places, then it
may be expressed as “p < .0001”.
13. What does it mean if Excel gives me a weird number like 1.2345E-67? For very small
and very large numbers Excel can present number using scientific notation, with “E” meaning
exponential. Therefore, what 1.2345E-67 means is that the number is 1.2345 times 10 raised
to the -67th power (i.e., a very small number). If you don’t like this way of displaying the
number then change the cell format from “general” to “number” and specify an appropriate
number of decimal places (do this by right clicking in the cell then choosing “Format cell”).
14. Which type of t-test do I use and how do I carry it out? You will test three hypotheses
about means and they require more than one type of t-test. The materials for Week 5 tutorials
give examples of each type of t-test and how to carry out the statistical tests, so you can use
these materials as a model for how to do these analyses. In particular, the handout shows how
to carry out both paired and two sample t-tests. You will need two sample t-test (two-tailed,
equal variances) for Questions 4 and 6, and paired t-tests (two-tailed) for Question 2. Note
that on the “Week 5 Lectures and Tutorial” Canvas page there are links to files giving
answers to the exercises for Week 5.

If you are using an older version of Excel or not using Windows then it is possible that the
function names are not identical to the ones we have given you. For example, the t-test
function used to be called “ttest” rather than “t.test”. We can’t give you all the possible
variations, but normally the names of the functions are very similar across the versions of
Excel, so it should be easy to find the equivalent functions. To make sure that a function
works as expected you can test them using the data from Week 5 tutorials to make sure that
they produce the expected output.
15. Do I specify one-tailed or two-tailed when using the t-test function? Use two-tailed even
though the prediction may have a direction. Using a one-tailed test implies that a result in the opposite
direction to predicted would be ignored, which is rarely the case.
16. Do the three issues for Question 10 need to be distinct? Yes, the assignment description says
“identify three different issues” so you will lose marks if you just present variations on the same issue.
If you are not sure if your issues are distinct then ask your tutor.
17. How do we present Issues 1,2, and 3 in Question 10? Clearly label each one ‘Issue 1”,
Issue 2” and “Issue 3” and to make it really clear put them into separate paragraphs. If you
use material from lectures when answering this question then you do not need to give
citations, but if you use material from outside of lectures then you should provide the citation.
18. Do I have to stick to the 750 word limit? Yes, part of the assignment is writing to a
word limit. Note that we will not penalize you unless you exceed the word limit by 10%, but
be careful about going right up to the limit because how you count words may not be exactly
the same as the way we do. Note that Question 13 does not count towards the word limit
because if you read more we don’t want to penalize you when you cite what you have read.
Note that the description of the Assignment when it specifies the word limit says that
Question 14 does not count, but it is Question 13 that foes not count.
19. Do in-text citations count towards the word limit. Yes. If you are unsure what counts
towards the word limit, then ask.
20. Do I have to find more papers on Fermi problems? No, all you have to read is the
Ärlebäck and Albarracín (2019) paper we cited in the assignment description, and which you
must refer to when answering Question 13. Reading more might help you with the questions
asking you to make an evaluation, such as Question 13. However, doing so is not required
and you could answer this question effectively just based on what you have been given.
If you use words or ideas from something you have read then you must properly cite the
source and include it as part of your reference list in Question 13. Otherwise, you are
plagiarising and may be penalized.
21. Is there a penalty for having an assignment that is too short? There is no penalty for
using less than 750 words for the assignment, if you can answer the questions effectively with
fewer words then that is fine.
22. Can I talk to other students and still avoid plagiarising? You can discuss the
assignment with other students, but you must write your own assignment. To minimize the
risk of plagiarism you should not exchange electronic copies (e.g., files, e-mails, texting) of
you answers with other students.
