## This week's topics

This week, we will discuss pie charts, line charts, and what-if tools. Choose one of these topics and discuss how you might use one in your job or within a school project - not including the homework for this class. Remember, any questions that you answer throughout this lecture will count towards your engagement grade.

## Pie Charts

There are many reasons for viewing data in a pie chart, such as ways to display percentage or proportional data. You might remember learning fractions (parts of a whole) by viewing a pie chart.

One way that I like pie charts is when I am reviewing my my mutual funds data. When I log into my financial accounts, I like to view how much of my money is invested in small cap vs. large cap vs. real estate vs. international by seeing a colorful pie chart. It is marked with a percentage for each category. Can you think of a way you might use a pie chart?

Generally, experts say that pie charts should contain 6 or fewer categories, otherwise, it may be difficult to view.

## Line Charts

Line charts or line graphs are used to display a series of information. This is a basic type of graph that is used in many fields to display information in different ways.

Two examples that I use this type of graph is for my financial statements. I like to view my earnings/losses over time. I also like to view my consumers power usage by looking at a line graph. I can see how much power was used during each month. This view makes a good comparison.

Can you think of other examples in which a line chart or graph might be used? What are other types of graphs or charts that we can create using Excel? What might those types of charts/graphs be used to display?

## Excel's Goal Seek Analysis Tool
