Which of the following choices this sort of error? (Choose two.)
  1. Type/error
  2. Type//error
  3. False negative
  4. False positive
Correct answer: BC
Question 2
For a variable salary we have the statistics as shown in the figure below. 
  
The reported Mean is incorrect because a value, -9999, is included in its calculation. How can this situation be fixed? 
  1. Define -9999 as a system-missing value 
  2. Remove all cases with the value -9999 for the variable salary from the data file
  3. Define -9999 as a user-missing value

  1. create a new case in your merged data
  2. highlight a specific case in one of your variables
  3. create a variable identifying the case data source
  4. create a variable identifying the variable data source
Correct answer: C
Question 10
Which operation does this Identify Duplicate Cases dialog not perform? 
  
  1. Identify duplicate cases with the same CUSTID number
  2. Sort in ascending order duplicate cases within CUSTID by the date of travel (TRAVDATE)
