$1.$ Tableau Dashboard: For this problem, you should create a dashboard in Tableau that in$-$

cludes several visualizations to help management better understand the data. Below is some

background about the problem.

Pelican Stores, a division of National Clothing, is a chain of women$$s apparel stores

operating throughout the country. The chain recently ran a promotion in which discount

coupons were sent to customers of other National Clothing stores. Data collected for a

sample of $100$ in$-$store credit card transactions at Pelican Stores during one day while the

promotion was running are contained in the file PelicanStores. Table $3\mathrm{.}13$ shows a portion

of the data set. The Proprietary Card method of payment refers to charges made using a

National Clothing charge card. Customers who made a purchase using a discount coupon

are referred to as promotional customers and customers who made a purchase but did

not use a discount coupon are referred to as regular customers. Because the promotional

coupons were not sent to regular Pelican Stores customers, management considers the

sales made to people presenting the promotional coupons as sales it would not otherwise

make. Of course, Pelican also hopes that the promotional customers will continue to shop

at its stores.

Your task is to create a Tableau dashboard to help management gain important insight from

this dataset. Your Tableau dashboard can include any of the following and$/$or any other visual$-$

izations you think would be helpful. $($You might want to spend some time playing around and

exploring the data before deciding what to include.$)$

These are just some ideas to get you started:

$$ Histograms showing percent frequency distribution for one or more of the key variables

$($number of items purchased, net sales, method of payment, gender, marital status, and

age$).$

$$ A sorted bar chart showing the number of customer purchases attributable to the method

of payment.

$$ A scatter chart to explore the relationship between net sales and customer age.

$$ A chart to examine whether the relationship between net sales and age depends on the

marital status of the customer.

$$ A side$-$by$-$side bar chart to examine the method of payment by customer type $($regular or

promotional$).$

$$ Other visualizations you think would provide insight!

Your submission should contain a link to your dashboard on Tableau Public and

a couple paragraphs about what the viewer can learn by looking at your dash$-$

board$/$story$.($On Tableau Public, also go into settings and set $$Show Viz on

Profile$$ and $$Allow Access$$ to both be off.$)$

$2.$ Pie Chart Alternatives: The total number of term life insurance contracts sold in Problem $13$

in Chapter $3$ in our textbook is $199.$ The following pie chart shows the percentages of contracts

sold by each salesperson.

Answer the problems below using complete sentences and explanations where appropriate.

Write a paragraph explaining multiple problems with using this pie chart to display these data.

What type of chart would be preferable for displaying the data in this pie chart, and why?

Then create a chart to display the data that conveys the data better than the pie chart. Format

the chart and add data labels to improve the chart$$s readability.
