Where to enter data

• Spreadsheet
• Text file
• Database

• Form (web or GUI databases)

• All of these are reasonable options
• When used properly spreadsheets or forms for databases can provide additional protection against bad data being entered
• Be careful of data conversion issues from spreadsheets

Quality Assurance

• Stopping bad data from ever being entered

• Let’s us set rules about what values can be entered into a column

• Select an area of cells, most often a column
• Data -> Data Validation
• Choose the data type: Whole numbers (only that type can be entered)
• Set limitations
  • Use Data to set the type of limitation: between
  • Then use additional boxes to provide specifics: 1 and 10
• Add a message to explain what goes in a cell in Input Message

• Add a useful error message using `Error Alert

• Make lists of choices
  • Allow = List
  • Enter list values in Sources: DM, DO, DS, PP, PM

Quality Control

• Looking for bad data that has already been entered
• Sort
• Graph
• Check for realistic ranges of values
