I have 2 groups ('keypad' and 'touch screen'), and each group has teh number of participants who are 'right ahnded and left handed.

For key pad: 45 right handed and 42 left handed

For touch screen: 9 right handed and 15 left handed.

Can I use a two way ANOVA for this? the number of righthanded and left hnded for each group does not really differ, so can I use 2 way anova?

OR DO I need to have the same exact number of participants in each condition in ordr to perform two way ANOVA?

Please help!

Thanks
