Parameter	Formula	Value
Mean score of ‘gain in learning’	Mean post test score – Mean Pre test score	11.1
Absolute learning gain	{(Post test score- Pre test score)/Max score} × 100	55.55%
Relative learning gain	{(Post test score- Pre test score)/Pre test score} × 100	225.8%
Class average normalized gain(g)	Absolute gain (%)/max achievable gain (%)	(0.73) 73%
Average of single student normalized gain (gavg)	Summation of g of individual students/N	71.01%
Effect size	(Post test score - Pre test core)/ Average spread of Std deviation	4.13
