Calculation - Count - Count Each Column

This tool is used to count the number of cells within each column of a table whose values match certain conditions:

Are greater than, or less than, a certain number.
Are greater than or equal to, or less than or equal to, a certain number.
Are within a specified range of numbers.
Are missing values (NA).
Are identical to a specific category label.
Satisfy a combination of conditions or ranges such as those listed above.

Examples

This table shows Awareness results for a number of brands over a number of quarters:

Count Each Column can be used to count the number of brands that acheived a score of more than 80% eache quarter. The result is a new table with one result for each brand:

You can choose which rows and columns are included by modifying the options (see below).

Options

Input The tables to be used in the calculation.

Values to count Enter ranges, single values, or inequalities to include in this calculation. Allowed options include:

Single values, like 10 - include values exactly equal to a single value, e.g. values which are equal to 10.
Sequences of values, like 1, 2, 3.5 - include values that are exactly equal to any of the entered values.
Ranges of values, like [1-10] - include all values that fall within a given range. For example, the range listed to the left will match values between 1 and 10, inclusive.
Inequalities, like >5.3 - include all values which satisify the inequality For example, the inequality to the left will match all values greater than 5.3. This works for greater than (>), greater than or equal to (>=), less than (<), and less than or equal to (<=).
Missing values, NA - match all values which are missing.
Infinities, Inf, -Inf - include all values which are infinity or negative infinity.

Categorical Labels When one or more of your inputs is a variable with categories, you can type in the labels of the categories that you wish to match.

Calculate for inputs with incomplete data If this option is checked, than any missing values in any of the inputs will be ignored in the calculation. If unchecked, then missing values are not removed before calculation and will propagate as missing values in the output.

Automatically match elements Only shown when there are multiple inputs to Input. This controls how and whether matching is done between the labels of the inputs. The default, "Yes - hide unmatched", will look for matching labels in the rows and columns of the inputs before proceeding with the calculation, and any rows/columns that are not contained in all the inputs will not be included in the output. See the Example. For a full description of the matching algorithm, see the Technical Details. "Yes - show unmatched" will also perform matching, but any unmatched rows (columns) will appear in the output as rows (columns) of all missing values. Selecting "No" for this option will cause any labels in the data to be ignored and not perform any matching. Selecting "Custom" will bring up two additional controls that allow for specifying the matching behavior for rows and columns separately.

Match rows Only shown if Automatically match elements is set to "Custom". Specifies the matching behavior when comparing row labels of the inputs. "Yes - show unmatched" and "Yes - hide unmatched" look for exact matches in the row labels in the inputs. "Fuzzy - show unmatched" and "Fuzzy - hide unmatched" perform fuzzy matching so that labels that differ only by a single character are considered to be a match.

Match columns Only shown if Automatically match elements is set to "Custom". The options are the same as Match rows, but control the matching between columns.

Rows to exclude Here you can type in row labels that should be excluded from the calculation.

Columns to exclude As above, but for columns.

Technical Details

When there are multiple inputs, inputs that contain only a single row (column) may be recycled to a matrix/table with the same number of rows (columns) as the other inputs. For example, if the supplied inputs are a table with three rows and two columns and another table with two rows and a single column, the single column will be expanded by rows into a table with three rows and two columns with each row identical to the original column.

When Automatically match elements is set to Yes - show unmatched or Yes - hide unmatched, both exact matches and fuzzy matches (as described above) are considered, and the order of elements may be permuted so that the names match. It also may transpose an input if, for example, the column names of one input match the row names of another input.
