Cell reference that is fixed; want copied formulas to always *refer to the same cell* if there is a constant

Absolute Reference?

SUM function

Adds the values in a range

Fill Handle

Average function =AVERAGE (number 1, number 2) Number 1 is required

Calculates the average of the range

Compare Values

Categories located in the first column of the look up table Used for matching to a lookup value

Look up Value

Category you want to find in a look up table

Absolute reference

Cell reference that *remains fixed* when the cell formula is copied to a new location. It includes a $ in front of the column letter and row number. $M$23 is the absolute reference to M23.

Relative reference

Rounds a number to the number of digits specified in num_digits

Lookup table

Stores the data you want to retrieve in categories
