Line Measurement: Based Child Psychological Test using MATLAB

The words 'test' and 'measurement', as used in psychology, are misleading because of the implied similarity to scientific measurements and medical tests. Conventional psychological testing is quite different from scientific measurements in natural sciences. When it comes to perception and specially comparing the preserved views of multiple people, it becomes extremely difficult to obtain a clear conclusion that who is perfect and to the point with the desired results. just take an example to predict the length of line drawn on a piece of paper it may be of any scaled length say 4cm but when we got to different people of different age group and ask for the length their view will be differing on a regular basic. As perception is highly individual dependent we can't say that one is right or wrong here every one is right in his con collusion because it is what he thinks is right and not is what in actual the results are here actual results refers to the scaled length. All results are implemented in MATLAB 7. 0.
