Question 1

Which of the following is not a guideline for presenting good graphs?
A) Graphs should be properly scaled along each axis.
B) Any chartjunk used in a graph should be labelled.
C) The scale on the vertical axis should begin at zero.
D) All axes on a graph should be properly labelled.

Accepted Answer

Chartjunk refers to all the unnecessary or distracting decorations in graphs such as excessive decoration and styling that do not improve the reader's understanding of the data. Good practice in graph design advises against the use of chartjunk, rather than labeling it. The other options (A, C, D) are indeed guidelines for presenting good graphs.

Question 2

You have collected data on the approximate retail price (in $)and the energy cost per year (in $)of 15 refrigerators.Which of the following is the best for presenting the data?
A) A contingency table.
B) A scatter plot.
C) A side-by-side bar chart.
D) A pie chart.

Accepted Answer

A scatter plot is the best way to present the data since it allows for a visual representation of the relationship between the two variables, retail price and energy cost per year, and helps identify any potential patterns or correlations. A contingency table is used for categorical data, a side-by-side bar chart is used for comparing different groups, and a pie chart is used to represent parts of a whole.

Question 3

One of the guidelines for presenting good graphs is that the scale on the vertical axis should begin at zero.

Accepted Answer

This guideline is important because starting the scale at a value other than zero can distort the visual representation of the data and create a misleading impression. For example, a bar graph that starts at a value greater than zero can make differences between bars seem larger or smaller than they really are. Starting the scale at zero ensures the relative height of each bar accurately reflects the magnitude of the data.

A) A two-way classification table.
B) A time-series plot.
C) A pie chart.
D) A histogram.

Accepted Answer

A time-series plot is the best choice for displaying data that changes over time, such as the number of births rising for five consecutive years. It will provide a clear and visual representation of the trend over time. A two-way classification table, pie chart, and histogram are not suitable for this type of data.

Question 9

Arnold would like to view up-to-the-minute operational status indicators about his business,such as number of purchases,daily sales figures,and stock information.Which of the following should he use?
A) A dashboard
B) A sparkline
C) A gauge
D) A bullet graph

Accepted Answer

A dashboard is the best choice as it is designed to provide real-time operational status indicators in an easily digestible format. It can display a variety of metrics, including number of purchases, daily sales figures, and stock information. The other options, such as sparkline, gauge, and bullet graph, are more geared towards displaying specific types of data and may not be as effective at providing an overall view of operational status.

Question 10

Which of the following refers to skills,technologies and practices for continuous iterative exploration and investigation of past business and performance to gain insight and drive business planning?
A) descriptive analytics
B) predictive analytics
C) business analytics
D) prescriptive analytics

Accepted Answer

Business analytics refers to the skills, technologies and practices for continuous iterative exploration and investigation of past business and performance to gain insight and drive business planning. Descriptive analytics is a type of business analytics that focuses on understanding historical data. Predictive analytics uses statistical techniques to predict future outcomes based on historical data. Prescriptive analytics recommends actions to achieve a desired outcome based on predictive and descriptive analytics.

Question 11

Drill-down is a method of data discovery that involves revealing data that underlie a higher-level summary.

Accepted Answer

Question 13

A bullet graph is a horizontal bar chart inspired by a thermometer.

Accepted Answer

A bullet graph is indeed a horizontal bar chart that resembles a thermometer in terms of its visual appearance. It is typically used to display key performance indicators and can provide more context than a traditional bar chart.

Question 14

A marketing analyst is evaluating the effectiveness of advertising by comparing weekly sales volumes and weekly advertising expenditures.Which of the following is the most appropriate for displaying this information?
A) A scatter plot.
B) A pie chart.
C) A histogram.
D) A bar chart.

Accepted Answer

A scatter plot is best suited to display the relationship between two continuous variables such as sales volumes and advertising expenditures. It allows the analyst to visually examine any patterns or trends in the data points and determine if there is a correlation between the two variables. A pie chart is not appropriate for comparing two continuous variables, and a histogram is better suited for showing the frequency distribution of a single variable. A bar chart may be used to compare discrete categories, but it is not as effective in displaying the relationship between two continuous variables.

Question 15

An economist is evaluating the relationship between the inflation rates for Australia and New Zealand.Which of the following is the best for presenting the data?
A) A contingency table.
B) A time-series plot.
C) A histogram.
D) None of the above.

Accepted Answer

A time-series plot would be the best choice for presenting the relationship between the inflation rates for Australia and New Zealand over time. This would allow for easy visualization of any patterns or trends in the data. A contingency table would be more appropriate for categorical data, and a histogram would be more appropriate for showing the distribution of a single variable.

Question 16

_________helps users to visualize two variables,one of which must be categorical.
A) Bullet graphs
B) Treemaps
C) Gauges
D) Sparklines

Accepted Answer

Treemaps can effectively display two variables by using color coding and size of rectangles. One of the variables must be categorical, while the other can be numerical. The size of the rectangle represents the numerical variable, while the color indicates the categorical variable.

Question 17

Which form of analytics focuses on the near future?
A) descriptive analytics

Question 19

You have collected data on the number of households in Sydney actively using online banking and/or online bill payment from 2000 to 2018.Which of the following is the best for presenting the data?
A) A pie chart.
B) A side-by-side bar chart.
C) A time-series plot.
D) A stem-and-leaf display.

Accepted Answer

A time-series plot would be the best choice to present the data because it shows how the number of households using online banking/bill payment has changed over time. Using a time-series plot, trends and patterns in the data can be easily identified, allowing for a more informed analysis of the data. A pie chart would not be appropriate for this type of data because it doesn't show changes over time, and a side-by-side bar chart would be better suited for comparing data across different categories rather than across different time periods. A stem-and-leaf display would not be appropriate for presenting this type of data because it is better suited for showing the distribution of a small dataset rather than a large dataset across time.

Question 20

When using business analytics methods such as treemaps,gauges,and bullet graphs,colour spectrums that run from _________ should be avoided.
A) red to green
B) white to black
C) yellow to blue
D) blue to green

Accepted Answer

Red to green color spectrums should be avoided because they are not distinguishable by color-blind individuals, which can make the data visualization less accessible.
