ITECH 5500 Professional Research and Communication
Assignment 1
Overview
This is an early intervention task worth 10% of the course. The purpose of the early intervention task is to make sure that you are engaging and on track to pass the course.
This task consists of a series of questions that go over the material that we covered in weeks one to four. They require you to think carefully about the material and tell me YOUR thoughts on what the answers should be and justify your answers where necessary.
This is an individual assignment that you are expected to complete by yourself. All outside sources of information must be acknowledged.

Assessment Details
1. Consider a survey in which customers’ perceptions of the service at a local store are gathered using a Likert Scale. Using this survey the customer gives a score of 1, 2, 3, 4 or 5 in response to a statement about the service. The scores represent
1 – Strongly Disagree
2 – Disagree
3 – Unsure
4 – Agree
5 – Strongly agree
For example, one of the statements might be
“The staff member appears knowledgeable regarding the store’s products”
and the customer would give a score based upon how much they agree with the statement. Now consider a situation in which 100 customers provide a response to this statement and they are distributed as follows
1 – Strongly Disagree 10 (10%)
2 – Disagree 25 (25%)
3 – Unsure 17 (17%)
4 – Agree 32 (32%)
5 – Strongly agree 16 (16%)
Now let’s assume that the store wants to summarise this data into a single score. They calculate this score by multiplying the number of responses by the number assigned, adding the five together and dividing by the number of respondents. In this case, (10 + 50 + 51 + 128 + 80) / 100 = 319/100
= 3.19
Explain why this value is not a valid summary of the data collected. Suggest a more valid way of representing the data. Justify your response.
[2 marks]
2. Consider the situation of a polling company which wants to predict the outcome of an upcoming election. They send their employees to stand on street corners in the capital city between 9 and 12 every week-day, with instructions to stop passers-by and ask them which party they will be voting for in the election. Does the data collected provide a true reflection of the likely outcome of the election? Explain why or why not? Justify your answer.
[2 marks]
3. We discussed four types of quantitative data in class – nominal, ordinal, ratio and interval. What types of data are collected from each of the following questions? Justify your answer.
a. The number of cars passing through an intersection in an hour, in whole numbers b. Kelvin thermometers
c. Fahrenheit thermometers
d. The type of mobile phone someone has (Nokia, Samsung, Apple, Other) e. A person’s height.
[2 * ½ + 1 = 3 marks]
4. Assume you are the lecturer for a university topic. You believe it is possible that attending lectures in person rather than viewing lecture recordings online will improve student performance. Explain how you could test this hypothesis in each of the following ways:
a. As a descriptive non-experimental study
b. A quasi experimental study
c. An experimental study
Which of the studies would give you the firmest evidence of whether your theory is correct? Justify your answers.
[3 marks]

Marking Criteria/Rubric
Question 1 – requires you to understand the nature of data collected using a Likert scale. You will need to understand the limitations of data collected in this way in order to be able to explain why the manipulation in the question is not valid. You will need to think of a better way to summarise the data that takes these limitations into account (you will need to be a little creative with this). You will require ½ page to a page for this answer.
A response that takes addresses all of the above concerns and shows depth of understanding of the concepts will attract the full 2 marks. Marks deducted for explanations that are not clear or which show misunderstandings.
Question 2 – you will need to be a little creative with this one. You will need to consider whether the people answering the survey are an accurate representation of all voters and explain (carefully) why or why not. You will need to think of situations in which you might consider the data more reliable. You will probably only require ½ page for this response but can write more if you think it is warranted.
A response that takes addresses all of the above concerns and shows depth of understanding of the concepts will attract the full 2 marks. Marks deducted for explanations that are not clear or which show misunderstandings.
Question 3 – Is a little more straightforward. For each sub-question you need to think about what the nature of the data is and which categorization suits it best. You must explain why you have chosen the category to get the mark for each. Just choosing a category will result in zero marks for that subquestion. Part e) allows for two possibilities – ½ mark for each.
Question 4 – You will need to think about the requirements for each type of quantitative study. Think of how the hypothesis might be tested in each of these three ways. You don’t have to go in-depth – just a paragraph to show that you understand the way the study would work. Each study is worth one mark each and part marks will be awarded for explanations that are not clear or contain misconceptions. The final question (about the firmest evidence) does not attract any marks per se but ½ mark will be deducted if the question isn’t answered correctly. You will probably require at least a page for this answer.
Feedback
Every attempt will be made to have feedback ready for the second half of tutorial 6. If this isn’t possible then email or other means will be employed.
