FrequencyTable[ <List of Raw Data L> ]
Returns a table (as text) whose first column contains sorted list of unique elements of 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 C>, <List of Raw Data L>]
If Cumulative = false, returns the same table as Frequency[ <L> ]
If Cumulative = true, returns a table whose first column is the same as in FrequencyTable[L] and the second contains cumulative frequencies of values in the first column.
FrequencyTable[<List of Class Boundaries C>, <List of Raw Data L> ]
Returns a table (as text) whose first column contains intervals (classes) and second column contains the count of numbers in L 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 C>,<List of Raw Data L>]
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[L] 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.
备注: This command is similar to Frequency Command and Histogram Command. Articles about these commands contain some related examples.
