Various Functions used in Excel 2010
Count Function--Specifically, the COUNT function totals only those cells that contain numbers. The function ignores
blank cells or those containing text data
CountA--- Excel’s COUNTA function is one of a group of Count Functions” that can be used to count the number of
cells in a selected range that contain data including text, numbers, dates, formulas, and error values. The function
ignores blank or empty cells. If data is later added to an empty cell the function will be automatically updated to
include the addition.
.
CountIF---The COUNTIF function combines the IF function and COUNT function in Excel. This combination allows you
to count the number of times specific data is found in a selected group of cells.
IF portion of the function determines what data meets the specified criteria and the COUNT part does the counting.
VLookUp--Excel's VLOOKUP function, which stands for vertical lookup, is used to find specific information that has
been stored in a spreadsheet table.
HLookUp--- Excel's HLOOKUP function, short for horizontal lookup, is used to find specific information that has been
stored in a spreadsheet table. HLOOKUP works much the same the Excel VLOOKUP function, or Vertical Lookup. The
only difference being that VLOOKUP searches for data in columns and HLOOKUP searches for data in rows.
