The data collected from the result of the experimental class using picture series showed the gained score of the experimental class was 445, the gained score of the
control class was 165. The different value of X after compared with the mean of gained score of the experimental class was -0.05 and the different value of Y after
compared with the mean of gained score of the control class was 0.09. The square value compared to the mean of gained score of the experimental class was 2415.16
and the square value compared to the mean for gained score of control class was 773.33
