Using Spreadsheet Functions

• Formulas = Functions• Functions are built into your

spreadsheet• Common functions are

average, sum, count, mode, mean

• They include a range of numbers or cells

=average(B1:B10)

=sum(A1+E3+D5)

=mode(B9:J11)

Working with Formulas

• Moving formulae- copying and pasting: Click + Drag! Session 3

• What difference does it make? Does moving or copying formulas make a difference? What do you notice about a formula when you copy it?
