The flashcards below were created by user jrad95 on FreezingBlue Flashcards. What would you like to do?


  1. Create Fields requiring least maintenance
    For example...
    Hire date, and birth date
  2. Store in smallest units of data as possible
    Use separate fields for address data instead of one that contains everything
  3. 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])
  4. 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
  5. IFERROR Function
    • Determines if a cell contains an error value  and display the message you choose 
    • Ex) #DIV/0, #NAME, #N/A
  6. What constitutes a fully qualified reference?
    using a table name and a structured reference
  7. Statisitcs
    A set of concepts, rules, and procedures that organize, understand, and help make informed decisions
  8. Variable
    property of an object or event that can take on different values
  9. Measures of Center(Central Tendency)
    • Plotting data in a frequency distribution shows the general shape of the distribution and gives a general sense of how the numbers are bunhced

  10. Measures of Spread(Variability)
    • Provide information about the degree to which individual scores are clustered about or deviate from the average value in a distribution 
    • Range,Variance,Standard Deviation
  11. Chi Squared
    • Measure of how expectations compare to results 
    • Must be random, raw, mutually exclusive, and drawn from independent variables
  12. t-test
    • used to determine whether a set or sets of scores are from the same Population 
    • Will tell you if a single variable is significant
  13. F-statistic/Test
    • Will tell you if a group of variables are jointly significant 
    • will contain both a F value and an F critical value
  14. F Value and F Critical
    If your f-statistic in a test is smaller than your F value, you can reject the null hypothesis
  15. p-test
    Assuming the F test showed the variables are jointly significant, shows which variables within a group are significant
