Overview (FREQUENCIES command)

FREQUENCIES produces tables that show frequency counts and percentages of the values of individual variables. You can also use FREQUENCIES to obtain summary statistics tables for both categorical and continuous variables. .

Options

Display Format. You can suppress tables and alter the order of values within tables using the FORMAT subcommand.

Statistical Display. Percentiles and ntiles are available for numeric variables with the PERCENTILES and NTILES subcommands. The following statistics are available with the STATISTICS subcommand: mean, median, mode, standard deviation, variance, skewness, kurtosis, and sum.

Plots. Histograms can be specified for numeric variables on the HISTOGRAM subcommand. Bar charts can be specified for numeric or string variables on the BARCHART subcommand.

Input Data. On the GROUPED subcommand, you can indicate whether the input data are grouped (or collapsed) so that a better estimate can be made of percentiles.

Basic Specification

The basic specification is the VARIABLES subcommand and the name of at least one variable. By default, FREQUENCIES produces a Frequency table.

Subcommand Order

Subcommands can be named in any order.

Syntax Rules

  • You can specify multiple NTILES subcommands.
  • BARCHART and HISTOGRAM are mutually exclusive.
  • You can specify numeric variables (with or without decimal values) or string variables.
  • Keyword ALL can be used on VARIABLES to refer to all user-defined variables in the active dataset.

Operations

  • Variables are tabulated in the order they are mentioned on the VARIABLES subcommand.
  • If a requested ntile or percentile cannot be calculated, a period (.) is displayed.
  • FREQUENCIES dynamically builds the table, setting up one cell for each unique value encountered in the data.

Limitations

  • Maximum 1,000 variables total per FREQUENCIES command.
