2. Cell reference

When the formula in a cell is referenced to another cell, the formula content changes accordingly, and this is relative reference. Instead, it locks a part of the formula, so that it is referenced to other cells and does not change accordingly. This is absolute reference. Hybrid reference is used to lock a row or column.

Relative reference: A1

Absolute reference: $ A $1. Press [F4] to enable it. the rows and columns behind $ are fixed and will not change.

Hybrid reference: $ A1, a $1 switch by [F4] ($ A1: Column A is locked, and the row can be changed; Row A $ is locked, and the column can be changed)

Sum: = sum (D5: G5)

Average: = average (D5: H5)

Maximum: = max (D5: D11)

Minimum value: = min (D5: D11)

Rank: = rank (H5, $ h $5: $ h $11)

Count: = count (D5: G5), counta
