Bar Charts rotated 90 degrees

Pie Charts

used to compare the parts of category to the whole. Typically each of the parts is expressed as percentages of the whole

Line Charts

to compare the values of a particular category over time

Spreadsheet elements

changeable inputs, outputs, and intermediate calculations

What-if Analysis

scenario manager, goal seek, and data tables

Scenario Manager

useful for examining the impact of several inputs to a spreadsheet model changing at the same time

Goal Seek

used to work backwards from an outcome calculation to determine an input condition necessary to arrive at the desired outcome

Data tables

we can specify a number of different possible states for one or two input variables and construct a table in our worksheet that calculates an outcome for our model based on each state of the input variables.

PivotTables

used to organize and summarize large amounts of data

allows us to perform some fairly sophisticated analyses quickly and easily
