Good morning sir, can I ask a question? can we use 50% group percentage used than 27% group percentage used because our sample size or the number of takers are only 13?
Hi, this is very informative and easy to follow. Very useful. May I know the reference that you used for the interpretation of difficulty and discrimination indices? Would greatly appreciate your kind response. Thanks.
Hi, thanks for asking. Here is the reference for the interpretation: De Guzman, E. and Adamos, J. (2015). Assessment of Learning 1. Adriana Publishing Co. Inc.
