To construct frequency histograms of samples in the main application form of STATISTICA its necessary to choose the function Graphs. In the window of this function we choose 2D graphs, and in it kind of graphical construction Histograms fig.1.10.

Fig. 1.10. Forms for the procedure of constructing frequency histograms

In the window 2D Histograms task of attributes constructing histograms

In option Quick we set:

- after pushing the buttion Variables the name of the data sample, which was given to her (ATTENTION! Only one sample!);

- in the window Graph type - Regular;

- on activated (stands dot) position ategories set the number of sites that will be broken range of values ​​of the sample (recommended 5 : 7);

In options Additionally:

- set in the window Type of fitting the view Normal.

- in the window View type we choose Standard.

After this press .

Type frequency histogram approximation of the normal law distribution shown in Fig.1.11.

Fig.1.11.The result of constructing the frequency histogram

 

After performing last procedure is necessary to test the distribution belonging to other law. For the latter case, the in option "Advanced" must be set:

- in the window View type reserve Standard;

- in the window Fitting type use the program proposed various distributions.
