The study involves two independent variables - method of presentation (standard lecture vs. computer presentation) and type of lecture (psychology, English, statistics) and their relation to lecture comprehension. Thus a two-way ANOVA is the best choice, with factor 1 being presentation (with two levels) and factor 2 being lecture type (with three levels).
