ages and line graphs for presenting trends.

2. What is the purpose of using charts?

Sample answer:
Charts provide an easier means of understanding large quantities of data. Looking
through raw data can be tedious, but a chart or graph can clearly show the relation-
ships and trends.

3. Can you cite a type of chart or graph you often use and explain how you de-
scribe it?

Sample answer:
I frequently use line graphs to show fluctuations in sales of our products. I explain the
graph by describing the decline and rise in sales, the degree of each and the period
wherein there seems to be a plateau.

1. The year has ended and you are tasked to make a report on the sales of your
product for each month of the year. What would be an appropriate chart or
graph to use? Please give a sample description of the graph.

Sample answer:
I would prefer to use a line graph so trends will be easily shown. There was an upward
trend over the year. From the start of the year until March, there was a steady rise in
sales. For the months of April and June, sales were relatively stable. From July to Octo-
ber, there was a steep rise in sales. Then, there was only a gentle slope from November
until the end of the year. Overall, sales increased for the whole year, although the rate
of increase differed among months.

2. The operations manager in your company was alarmed due to a sharp de-
crease in volume of sales last month. He is requiring you to create a presen-
tation of reports to see how the sales differed in your six main branches.

Sample answer:
I would use a vertical bar chart to present the sales in the different branches last month.
The branches would be in the x-axis and the sales would be in the y-axis. According
to the data, our highest value was from U.S.A. with 1.7M units sold and the lowest was
Singapore with 830,000 units sold. U.S.A. accounted for 22.22% of net sales, followed
by Canada and Australia with 21.83% and 21.57%, respectively. The three lower ones
who had sales figures less than 1M units were Malaysia, Indonesia and Singapore.
These accounted for 11.9%, 11.63 and 10.85% of total sales, respectively. I will point to
the corresponding columns and values as I explain the graph.
