FrequencyTable Command

FrequencyTable( <List of Raw Data> )

Returns a table (as text) whose first column contains sorted list of unique elements of list L and second column contains the count of the occurrences of value in the first column. List L can be numbers or text.

FrequencyTable( <Boolean Cumulative>, <List of Raw Data> )

If Cumulative = false, returns the same table as Frequency( <List of Raw Data> ) If Cumulative = true, returns a table whose first column is the same as in FrequencyTable( <List of Raw Data> ) and the second contains cumulative frequencies of values in the first column.

FrequencyTable( <List of Class Boundaries>, <List of Raw Data> )

Returns a table (as text) whose first column contains intervals (classes) and second column contains the count of numbers in List of Raw Data, which belong to the interval in the first column. All intervals except the highest interval are of the form [a, b). The highest interval has the form [a, b].

FrequencyTable( <Boolean Cumulative>, <List of Class Boundaries>, <List of Raw Data> )

If Cumulative = false, returns the same table as FrequencyTable( <List of Class Boundaries>, <List of Raw Data> ) If Cumulative = true, returns a table whose first column is the same as in FrequencyTable( <List of Raw Data> ) and the second contains cumulative frequencies of values in the first column.

FrequencyTable( <List of Class Boundaries>, <List of Raw Data>, <Use Density> , <Density Scale Factor (optional)> )

Returns a table (as text) whose first column contains intervals (classes) and second contains frequencies for the corresponding Histogram Command.

FrequencyTable( <Boolean Cumulative>, <List of Class Boundaries>, <List of Raw Data>, <Use Density> , <Density Scale Factor (optional)> )

Returns a table (as text) whose first column contains intervals (classes) and second contains frequencies for the corresponding Histogram Command.

FrequencyTable( <List of Raw Data>,<Scale Factor (optional)> )

Returns a table (as text) whose first column Value contains a sorted list of unique elements of the <List of Raw Data> and second column Frequency contains the count of the occurrences of value in the first column multiplied by the <Scale Factor>. The list can be numbers or text.

FrequencyTable({"red", "red", "green", "green", "blue"}, 5) returns a table with first column Value with entries blue, green, red (alphabetical order) and second column Frequency with entries 5, 10, 10.

FrequencyTable({1, 1, 1, 2, 2, 3, 3, 4, 5}, 2) returns a table with first column Value with entries 1, 2, 3, 4, 5 and second column Frequency with entries 6, 4, 4, 2, 2.

In the list there appears 1 three-times, so the count of the occurences of 1 (=3) has to be multiplied by the scale factor 2 to get entry 6 in the second column.
