Summarizations and Tabulations  Perform a tabulation  
The Type of Summary dropdown in the Tabulation dialog contains a number of summarizations.
number of records  The number of rows in each group.

% of total records  The number of rows in each group as a percentage of all rows.
Note: The result is a whole number, not a fractional value. For instance, a result of
20% would be represented as 20, not 0.20.

fraction of total records  The number of rows in each group as a fraction of all rows.
Note: The result is a fractional value. For instance, a result of 20% would be
represented as 0.20.

other groups.

number of unique values  The number of unique values in the Column for each
group.

sum  The subtotal of the Column for each group. (numeric
columns only)

% of grand total  The subtotal of the Column for each group as a percentage
of the grand total. (numeric columns only)
Note: The result is a whole number, not a fractional value. For instance, a result of
20% would be represented as 20, not 0.20.

fraction of grand total  The subtotal of the Column for each group as a fraction of
the grand total. (numeric columns only)
Note: The result is a fractional value. For instance, a result of 20% would be
represented as 0.20.

rank of sum  The rank of each group, in terms of its Column subtotal,
with respect to the other groups. (numeric columns only)

average  The average of the Column for each group. (numeric
columns only)

rank of average  The rank of each group, in terms of its Column average,
with respect to the other groups. (numeric columns only)

the Reference Column, for each group. (numeric columns
only)

highest number  The highest number in the Column for each group.
(numeric columns only)

lowest number  The lowest number in the Column for each group.
(numeric columns only)

first value  The first value in the Column for each group.
(alphanumeric and numeric columns) This is the first value based on the current sort order of the table (i.e., the way the data is shown when the table is viewed multiple rows at a time).

last value  The last value in the Column for each group. (alphanumeric and numeric
columns) This is the last value based on the current sort order of the table (i.e., the way the data is shown when the table is viewed multiple rows at a time).

standard deviation  The standard deviation of the Column for each group.
(numeric columns only)

variance  The variance of the Column for each group. (numeric
columns only)

weighted std dev  The standard deviation of the Column, weighted by
the Reference Column, for each group. (numeric columns
only)

weighted variance  The variance of the Column, weighted by
the Reference Column, for each group. (numeric columns
only)

sum of squares  The sum of squares of the Column for each group.
(numeric columns only)

correlation  The correlation of the Column and the Reference
Column, for each group. (numeric columns only)

covariance  The covariance of the Column and the Reference
Column, for each group. (numeric columns only)

dot product  The dot product of the Column and the Reference
Column, for each group. (numeric columns only)

number of valid values  The number of nonN/A values in the Column for each group. 
number of N/As  The number of N/A values in the Column for each group. 
number of valid pairs  The number of rows where both the Column and the Reference Column are not N/A, for each group. 
number of N/A pairs  The number of rows where either the Column or the Reference Column is N/A, for each group. 
median  The median of the Column for each group. (numeric
columns only)

mode  The mode of the Column for each group. (numeric columns
only)
