Create Fields requiring least maintenance
For example...
Hire date, and birth date
Store in smallest units of data as possible
Use separate fields for address data instead of one that contains everything
Structured Reference
A tag of field name used in a formula or function
If data table range changed the structured reference will remain valid and adjust as the table changes
If you add/delete columns/rows, the cell references may no longer be valid but the structured references will
Ex)=SUM(DeptSales[SaleAMt])
Qualified Reference
Means the table is explicitly identified, you may used the table name in the formula
If you use a structured reference within a table it can be unqualified
if you use a structured reference outside a table you need to use a fully qualified reference
IFERROR Function
Determines if a cell contains an error value and display the message you choose
Ex) #DIV/0, #NAME, #N/A
What constitutes a fully qualified reference?
using a table name and a structured reference

If your f-statistic in a test is smaller than your F value, you can reject the null hypothesis
p-test
