HOW TO ORGANISE DATA

  • Data in raw records form are the data organised in the way, so that each row includes information about another studied object (like a patient, a firm etc.).

    Example. Raw data (sex-education.pqs file) ANG_dane surowe
  • The contingency table presents a joint distribution of 2 variables. There are observed frequencies (natural numbers) inside the table.

Example. A contingency table (sex-education.pqs file) ANG_trans_tabele_cont

HOW TO CONVERT RAW DATA INTO CONTINGENCY TABLE

You can start the operation of converting raw data into a contingency table by selecting Data›Create table... Usually, there is the whole data sheet available for this operation (default). However, if you start the conversion from selecting a piece of data, you will be able to reduce the area available only to the selection.
A contingency table can be designed by selecting the variables forming row and column labels. If a preview of the table does look like the expected one, you confirm the choice by selecting Run. The returned result will be placed in a new datasheet.

HOW TO CONVERT CONTINGENCY TABLE INTO RAW DATA

You can start the operation of converting a contingency table into raw data by selecting Data›Create raw data... In the window of data transformation, we enter appropriate numbers and headers of rows and columns. You confirm the choice by selecting Run. The returned result will be placed in a new datasheet.

If we convert a table which is placed in a datasheet, we have to select it (with or without header) before the conversion of the table into raw data. Then, in the conversion window, the table will be places automatically. It is also possible to use other labeled tables as a saved selection.
