Tutorial

Firstly, in order to obtain the analysis of the data, it is necessary to introduce it. In order to this, you have to select the type of data that you want to introduce and the number of variables. There are four combinations:

· One-dimensional variables using countinuous data (grouped in intervals)

· One-dimensional variables using quantitative discreet data

· One-dimensional variables using qualitative discreet data

· Two-dimensional variables using discreet data

In order to select the type of data, you can use the can use the drop-down lists that appears in the main window.

Once selected the type of data, you will introduce them. In order to this, if the data are tabular, you don’t have more than type them in the main window. If you don’t have the tabular data, you click the button Not Tabular of the main window or you select the option Introduce Not Tabular of the ║Edition║ menu. Remember that decimal numbers are ALWAYS entered using dots. Commas are not allowed.

If you previous have saved the data (║File║|Save), you can recover it using the Open option from the ║File║ menu.

Once introduced the data, you can edit them using the tools of the ║Edition║ menu. From that menu you can insert rows, columns and create a new table among other options. Many of these options have a quicker access through buttons located in the main window.

You can check that the introduced data are correct through the option Check Errors of the ║Analysis║ menu or from the quick button equivalent.

After introducing the data, you will want to analyze them. In order to this uses the tools of the ║Analysis║ menu. The first thing that you will want to obtain will be to fill the columns of the table. In order to this, you use the option Fill Table.

Inside the Analysys option you will obtain most of the statistical measures of frequent use. You will also obtain the percentiles and mementos for the desired values.

Once obtained the measures, you could want to extend them with your own calculus. In order to this, you use the Calculator option of the ║Tools║ menu.

You could also obtain a graphic representation of that analysis through the Plot option of the ║Tools║ menu.

Remember that exist example data in order to become familiar with the program in the Examples folfer, inside of the the installation folder of the program. This folder is usually at C:\Program Files\Esta+.

Identification of outliers according to the interquartile range

The observations outside of the range:

but inside the range:

are considered as outsides according to the method of identification of outliers according to the interquartile range.

The observations outside of the range:

are considered as far outsides according to the method of identification of outliers according to the interquartile range.
