NEW DATA lets you enter new data into ViSta. 

When you use NEW DATA, you will see a dialog box that asks you to specify the DataType of the data you wish to enter, and which suggests names for specific information that is needed for each datatype. See the VARIABLE AND DATA TYPES subtopic of the help panel's MANAGING DATA topic for further information about datatypes.

The three datatype choices are:

FREQUENCY TABLE DATA 
These data have entirely NUMERIC variables whose values specify frequencies. The values must all be non-negative (or missing). The data may be a one-way classification of the frequencies of the row (or column) entities, or a two-way cross-classification (crosstabs) of the co-occurance frequency of the row and column entities. These data may be converted into FREQUENCY CLASSIFICATION or CATEGORY data.

MATRIX DATA
These data have entirely NUMERIC variables whose values specify the strength of relation (correlation, covariance, co-occurance probability, distance, etc.) between the row and column entities. The observation and variable entities must be the same. Each value species an element of a square matrix. There may be more than one matrix. 

ALL OTHER TYPES
This choice (the default) is appropriate for all datatypes except the two choices above it.  Note that this includes several specific datatypes other than the two specified. If you choose ALL OTHER TYPES, ViSta will determine which datatype is appropriate. 

Depending on the DataType, ViSta suggests a name for the new data (and for the rows and columns of new frequency data). You may change these suggestions by typing a name in the appropriate place.

After you click OK, you will see a datasheet icon on the workmap, and a new datasheet. If this datasheet doesn't have enough rows and columns for your data, use the datasheet's popup menu to ADD ROWS AND/OR COLUMNS. See the ENTERING DATA topic for more information on using the datasheet.
