In Ober’s Analysis system, encoding period should be of 20 minutes. Encoding

article is marked vertically in which communication flow shows that which classes
are followed by which ones.

14.3 Analysis and Decoding Procedure

Similar to the Flander’s, a 20 × 20 Analysis table is created in order to analyze the communication fl ow
to class teaching. In the analysis table, 10 categories are combined from top to bottom. Every section of

table displays communication flow. The above drafting is included in the table in the following manner.
There are 400 sections in this 20 × 20 table while Flander’s table consists of only 100 parts. It is divided

into four communication flows. Each contains 100 sections. The process of creating this table is given
as follows:

Thus, 20 × 20 Analysis Table is created by encoding categories after marking the category combination
in the required section. Transitional Analysis is done in this table.
