Quantifying Observations:

When the behaviours  specified have  to  provide certain measurement then  some form of quantification  is  required.  The quantification usually takes the  form of  counting. The  count may be  of number  of  times that a subject  shows a particular  form of behaviour during a period  of observation. Here  observer  should be sure of when  one  act ends  and the next begins. It  is wise  to  break the period  of  observation into short  segments  and observer  can  then watch occurrence  or non-occurrence of particular behaviour under specified categories.
