By default, the MEANS
procedure produces the n, mean, minimum, maximum, and standard deviation.
Correct answer: d
To specify the variables
that PROC MEANS analyzes, add a VAR statement and list the variable
names.
Correct answer: a
Unlike Age, Height,
or Weight, the values of IDnum are unlikely to yield any useful statistics.
Correct answer: a
Unlike CLASS processing,
BY-group processing requires that your data already be indexed or
sorted in the order of the BY variables. You might need to run the
SORT procedure before using PROC MEANS with a BY group.
Correct answer: b
A CLASS statement produces
a single large table, whereas BY-group processing creates a series
of small tables. The order of the variables in the CLASS statement
determines their order in the output table.
Correct answer: a
You can use PROC MEANS
to create the table. The MEANS procedure provides data summarization
tools to compute descriptive statistics for the variables Age, Height,
and Weight for each Sex group.
Correct answer: c
By default, PROC FREQ
creates a table for all variables in a data set.
Correct answer: c
Both continuous values
and unique values can result in lengthy, meaningless tables. Frequency
distributions work best with categorical values.
Correct answer: d
An asterisk is used
to join the variables in a two-way TABLES statement. The first variable
forms the table rows. The second variable forms the table columns.
Correct answer: d
An asterisk is used
to join the variables in crosstabulation tables. The only results
shown in this table are cell percentages. The NOFREQ option suppresses
cell frequencies, the NOROW option suppresses row percentages, and
the NOCOL option suppresses column percentages.
