You have been asked to create a categorical variable from a scale variable, income, illustrated in the histogram below. The resulting categorical variable must have 5 categories with an approximately equal number of cases in each category. Which way would you accomplish this using the IBM SPSS Statistics Visual Binning dialog?
Use the automatic option Equal Width Intervals
Use the automatic option Equal Percentiles Based on Scanned Cases
Use the automatic option Cutpoints at Mean and Selected Standard Deviations Based on Scanned Cases
Specify Cutpoints manually at 10000, 20000, 30000, 40000 & 50000
Correct answer: B
Question 2
If you build an expression manually, as opposed to using a function (e.g., specify (V1+V2)/2 instead of MEAN(V1,V2)), which statement is true?
If any of the variables used in the expression has a missing value, it will be ignored and the expression will proceed to evaluate with variables that have valid values.
It will always return a valid value for each case, regardless of whether one or more of the source variable values are missing.
If any of the variables used in the expression has a missing value, the result for that case is a system-missing value.
If any of the variables used in the expression has a missing value, you will get a notification pointing this out before you proceed.
Correct answer: C
Question 3
In the Aggregate data procedure, if you specify more than one Break Variable, ________________ in the Break Variables list will determine case order.
