An experiment was done to look at whether there is an effect of the number of hours spent practising a musical instrument and gender on the level of musical ability. A sample of 30 (15 men and 15 women) participants who had never learnt to play a musical instrument before were recruited. Participants were randomly allocated to one of three groups that varied in the number of hours they would spend practising every day for 1 year (0 hours, 1 hours, 2 hours). Men and women were divided equally across groups. All participants had a one-hour lesson each week over the course of the year, after which their level of musical skill was measured on a 10-point scale ranging from 0 (you can’t play for toffee) to 10 (‘Are you Mozart reincarnated?’). Which of the following tests could we use to
analyse these data?
A. Two-way repeated-measures ANOVA
B. Three-way ANOVA
C. t-test
D. Two-way independent ANOVA

Pronouncements about the incidence of reading disabilities/delays are often heard in media presentations and found in the lay press. Sometimes they are on-target, but other times quite off-base. If, as an expert in your field, you are asked, "How many students in the U. S. have a reading delay?" a reasonable answer would be:
A. Accurate estimates are difficult to obtain due to differences in the degree of discrepancy used to determine if a student is eligible for special services, but a reasonable estimate would be about 25% of the school-age population. B. Approximately 1% to 2% of students currently enrolled in public schools. C. Approximately 30% of elementary school children and 35% of middle and high school students. D. Estimates are difficult to obtain because different programs use different criteria to determine whose problems are serious enough to need special services, but a reasonable estimate is that about 15% have some literacy difficulties, with 3% of these having serious needs.
