DQ1 To determine whether a new sleeping pill has an effect
that varies with dosage, a researcher randomly assigns adult insomniacs, in
equal numbers, to receive either 4 or 8 grams of the sleeping pill. The amount
of sleeping time is measured for each subject during an 8-hour period after the
administration of the dosage. What type of design is this, and what type of
statistic is needed to analyze the data?
DQ2 Dr. Bill Board designs a 2 X 2 between-subjects
factorial design, where Factor A is word frequency (low or high) and Factor B
is category cues (no cues or cues). Assume that the data are interval. What
type of statistic is needed to analyze the data?
