2.1 Scenario
The Australian Electric Vehicle Council wants you to process and analyse the data set and then answer several
questions. The questions you need to answer are contained in the following memorandum.
Assume that your readers do not have an analytics background, so it’s important that you utilise “plain, easy to
understand language” in your answers. If you believe you need to include any technical terms, then you must explain
these in a clear and succinct manner using layman’s terms.
2.2 Memorandum
Date:
To:
From:
Subject:
20 December, 2022
You, Data Analyst
Jane Smith, CEO
Analysis of Electric Vehicle Data
Dear YourName,
Can you please ca
y out an analysis of the Electric Vehicle data (contained in the file EVData.xlsx) and prepare a
eport containing answers to the following questions.
Q1. Summaries of key variables of interest
Can you please provide me with separate summaries of the following variables, just by themselves? In other words,
please investigate each variable individually without reference to any other variable in the dataset.
(a) “Efficiency_WhKm” – average consumption of the battery in watt hours for each kilometer traveled.
(b) “BodyStyle” – style/size of the car.
Q2. Exploring relationships between two variables
(a) I would like to know if there is a link between the top speed of EVs (“TopSpeed_KmH”) and their price
(“Price”). I suspect that the higher the top speed, the higher the price will be, but I’d like to know if this is
actually the case. Therefore, I’d like you to establish from your sample data if there is any relationship
etween these two variables.
(b) I’m also interested to establish if there is a relationship between the drive type (“PowerTrain”) and the style
(“BodyStyle”).
(c) Further, it would be helpful if we knew if the drive type (“PowerTrain”) has any relationship with how
efficient an EV runs (“Efficiency_WhKm”).
Q3. Estimating EV measures
(a) I would like you to estimate how far EVs overall can drive on a single charge (“Range_Km”).
(b) I’m also interested to know if you can estimate the proportion of all EVs which are perceived as larger cars
(i.e., SUVs or Pickups) (“BodyStyle”).
Q4. Claims about EVs
(a) I read somewhere that acceleration (i.e., 0 to 100 km/h) for EVs (“AccelSec”) was 7 seconds.
I think that acceleration is lower than this figure for EVs (they can go from 0 to 100 km/h in less than 7
seconds). Is there any evidence to suggest that this is the case?
_________________________________________________________________________________________________________________________
MIS770 Foundation Skills in Data Analysis Assignment Two (T3, XXXXXXXXXXPage 3
(b) Another claim concerned market segments (“Segment”). The claim was that less than 20% of EVs belonged
to Segment D. Can you also check this claim against your survey data?
Q5. Appropriate sample size
Finally, I am concerned that the sample of 92 EVs is too small to provide accurate results as this seems hardly enough
data. If we ever decide to repeat the analysis, I would like to be able to:
calculate approximately the average range (“Range_Km”) to within 15 kilometers.

Therefore, how many EVs would we need to include in the next analysis to satisfy this requirement?
Regards, Jane
3.0 Report Requirements
• Your report must have a cover sheet containing your personal particulars and the Unit details, an executive
summary, introduction and conclusion.
• Your report should be no longer than 3 pages excluding cover sheet, and there is no need to include any
visualisations (i.e., Charts and Tables) or Appendices in the Report.
• The Charts/Graphics and Tables you create are only to be placed in the Data Analysis file (i.e. the Excel
spreadsheet) and not reproduced in the report.
• Your report is meant to be a stand-alone document. That is, readers should be able to read it without looking
at the data analysis. To this end, do not refer to the visualisations as “as you can see from Figure 1 etc”. You
need to interpret your data analysis visualisations for Jane in the report.
• Suggested Word formatting for the report: Single‐line spacing; no smaller that 10‐ point font; page margins
approx. 25mm, and good use of white space.
• Set out the report in the same order as in the originating Memorandum from Jane, with each section
(question) clearly marked.
• Use plain language and keep your explanations succinct. Avoid the use of technical or statistical jargon. As a
guide to the meaning of “Plain Language”, imagine you are explaining your findings to a person without any
statistical training (e.g., someone who has not studied this unit). What type of language would you use in that
case?
• Marks will be lost if you use unexplained technical terms, i
elevant material, or have poor presentation
organisation.
• All Microsoft Excel output associated with each question in the Memorandum is to be placed in the
co
esponding tab in the file EVData.xlsx
3.1 Data Analysis Instructions/Guidelines
In order to prepare a reply to Jane’s memorandum, you will need to examine and analyse the dataset EVData.xlsx
thoroughly.
Jane has asked a number of questions and your data analysis output (i.e., your charts/tables/graphs) should be
structured such that you answer each question on the separate ta
worksheet provided in your Excel document.
There are also five extra tabs in EVData.xlsx and you should use the various templates contained in these tabs in your
“Confidence Interval”, “Hypothesis” and “Sample Size” answers.
In order to effectively answer the questions, your data analysis output needs to be appropriate. Accordingly, you’ll
need to establish which of the following techniques are applicable for any given question:
• Summary Measures (e.g., descriptive statistics, Inc. outlier detection, percentiles).
• Comparative Summary Measures (i.e., descriptive statistics, outlier detection and percentiles for multiple values
of a variable).
• Suitable tables (such as a frequency distribution) and charts or graphics (such as histograms, box plots, pie
charts, ba
column charts, polygons) that will illustrate more clearly, other important features of a variable.
• Scatter Diagrams (used to visually establish if there is a relationship between two numeric variables).
• Cross Tabulations (sometimes called contingency tables), used to establish the relationships (dependencies)
etween two variables (see Additional Materials under Topic 2 – Creating Cross Tabulations in Excel using Pivot
Tables).
• Confidence Intervals. You can assume that a 95% confidence level is appropriate. We use confidence intervals
when we have no idea about the population parameter we are investigating. Additionally, we would use
confidence intervals if we were asked for an estimate. You should use the relevant Excel templates provided in
the dataset and copy them to the applicable question tab.
• Hypothesis Tests. You can assume that a 5% level of significance is appropriate. We use hypothesis tests when
we are testing a claim, a theory or a standard. You should use the relevant Excel templates provided in the
dataset and copy them to the applicable question tab.
• Sample size calculation: You can assume that a 95% confidence level is appropriate. You should include
comparisons for 90% and 99% and a recommendation for the appropriate sample size.
• To answer some questions, you may need to make certain assumptions about the data set we are using.
Mention these in your data analysis, where relevant. There is no need to mention this in the report.
Note: There is an appendix at the end of each chapter of the prescribed textbook which describes the basic Excel steps
associated with that topic. Chapters 1 to 9 are applicable for this assessment.
3.2 Submission
Your completed assignment should be submitted in two separate files:
• Report (Part A): A word document of no more than 3 pages (excluding title/cover page) that must not contain any
charts/tables/graphs. (Note: Do not submit a pdf document in lieu.). Please name your word document
Assignment2_yourstudentid.docx
• Data Analysis (Part B): An Excel document containing separate tabs/worksheets with charts/tables/graphs for
each question. Please note that all interpretations should be presented in your “Report” and the Excel document
should only contain your intermediate analysis and final output. Please (re-)name your Excel document
Assignment2_yourstudentid.xlsx
The assignment is to be submitted to the MIS770 assignment box in CloudDeakin before 8 pm, Thursday 19th
January 2023. Please ensure you include your name and student details in your Word document as well following
the above file naming convention. Failure to follow this convention may lead to a delay in receiving feedback and
marks.

Executive Summary:
The summary statistics of efficiency_whkm (average consumption of the battery in watt hours for each kilometer traveled). For the variable Bodystyle, we have drawn percentage frequency bar chart to show the variation in different body style according to their relative frequency percentage. For both continuous variable we have conducted co
elation test. The scatterplot between top speed and price of the car shows positive slope, which implies increase in one will cause significant increase in other. The co
elation coefficient is higher than 0.75. which is strong and positive. There is high degree dependence of topspeed over the price. There is also some exception like price is around 150000 and speed around 150. There is a significant strong relationship between price and top speed.
For assessment of relationship between powertrain and bodystyle, both are categorical variable hence we have conducted chi square test we will use chi square test. There are three types of powertrain like AWD, FWD and RWD and five types of BodyStyle. First, we have calculated cross tabulation of powertrain and bodystyle frequency. Similarly created estimated table for relative expected frequency in respective categories levels. We have tested hypothesis to estimate the acceleration for car 0 to 100 m/s in less than 7 seconds. We have tested hypothesis to estimate the that less than 20 percent of EVs belong to segment D.
Introduction:
The summary statistics of efficiency_whkm (average consumption of the battery in watt hours for each kilometer traveled) has shown in below table. Efficiency has average of 188.90 with standard e
or of 3.07 at five percent level of significance. It has minimum of 104 and maximum of 270 with the range of 166. The kurtosis and skewness are less than 1 and greater than 0 which implies our EV efficiency distribution is approximately normal. From confidence interval statistics we can conclude that at five percent level of significance the average estimate can vary from 182.71 to 194.89.

For the variable Bodystyle, we have drawn percentage frequency bar chart to show the variation in different body style according to their relative frequency percentage. BodyStyle SUV accounts for 49 percent of total vehicles on the contrary bodystyle Pickup accounts for only 3 percent of total vehicles.
The scatterplot between top speed and price of the car shows positive slope, which implies increase in one will cause significant increase in other. The co
elation coefficient is 0.77 which is strong and positive. There is high degree dependence of topspeed over the price. There is also some exception like price is around 150000 and speed around 150. There is a strong relationship between price and top speed.
For assessment of relationship between powertrain and bodystyle we will use chi square test. There are three types of powertrain like AWD, FWD and RWD and five types of BodyStyle.
First, we have calculated cross tabulation of powertrain and bodystyle frequency. Similarly created estimated table for relative expected frequency in respective categories levels.
