AVERAGEIF
function is used to calculate the average for a set of values that match a specific criterion

Column Charts/Bar Charts
used to compare different categories of items or the same category over time
A good rule of thumb would be to limit the number of categories (or time intervals) examined to between five and ten
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
