The modified data set contains secondary school math scores (out of 100%) from 395 secondary school students in Portugal (p:[[archiveJcs.uci.eduzledatasetsZStudent+ Performance). The researcher is interested whether alcohol consumption affects student's math scores on a state math test (represented as a percentage out of 100, e.g., 80%). The relevant variables are . the participants gender (0=female, 1=ma|e, total 187 males) . Age (range 15-22 years) . the number of alcoholic drinks per day during the week (ALC_weekday) . the number of alcoholic drinks per day on the weekend (ALC_weekend). Age and gender are entered in the first block, and ALC_weekday and ALC_weekend in the second block. Age and gender are entered in the first block, and ALC_weekday and ALC_weekend in the second block.
