The FREQUENCIES
procedure outputs frequency tables for specified
variables.
FREQUENCIES
can also calculate and display descriptive statistics
(including median and mode) and percentiles,
FREQUENCIES
can also output
histograms and pie charts.
The VARIABLES
subcommand is the only required subcommand. Specify the
variables to be analyzed.
The FORMAT
subcommand controls the output format. It has several
possible settings:
TABLE
, the default, causes a frequency table to be output for every
variable specified. NOTABLE
prevents them from being output. LIMIT
with a numeric argument causes them to be output except when there are
more than the specified number of values in the table.
AVALUE
. DVALUE
tables are sorted in descending order by value.
AFREQ
and DFREQ
tables are sorted in ascending and descending order,
respectively, by frequency count.
The MISSING
subcommand controls the handling of user-missing values.
When EXCLUDE
, the default, is set, user-missing values are not included
in frequency tables or statistics. When INCLUDE
is set, user-missing
are included. System-missing values are never included in statistics,
but are listed in frequency tables.
The available STATISTICS
are the same as available
in DESCRIPTIVES
(see DESCRIPTIVES), with the addition
of MEDIAN
, the data's median
value, and MODE, the mode. (If there are multiple modes, the smallest
value is reported.) By default, the mean, standard deviation of the
mean, minimum, and maximum are reported for each variable.
PERCENTILES
causes the specified percentiles to be reported.
The percentiles should be presented at a list of numbers between 0
and 100 inclusive.
The NTILES
subcommand causes the percentiles to be reported at the
boundaries of the data set divided into the specified number of ranges.
For instance, /NTILES=4
would cause quartiles to be reported.
The HISTOGRAM
subcommand causes the output to include a histogram for
each specified numeric variable. The X axis by default ranges from
the minimum to the maximum value observed in the data, but the MINIMUM
and MAXIMUM
keywords can set an explicit range. Specify NORMAL
to
superimpose a normal curve on the histogram. Histograms are not
created for string variables.
The PIECHART
subcommand adds a pie chart for each variable to the data. Each
slice represents one value, with the size of the slice proportional to
the value's frequency. By default, all non-missing values are given
slices. The MINIMUM
and MAXIMUM
keywords can be used to limit the
displayed slices to a given range of values. The MISSING
keyword adds
slices for missing values.
The FREQ
and PERCENT
options on HISTOGRAM
and PIECHART
are accepted
but not currently honoured.
