Sex and Direction.

Sex and Direction. In   the paper “The Relation of Sex and Sense of Direction to Spatial Orientation   in an Unfamiliar Environment” (Journal of Environmental Psychology, Vol 20,   pp.17-28), Sholl et al. published the results of examining the sense of   direction of 30 male and 30 female students. After being taken to an   unfamiliar wooded park, the students were given some spatial orientation   tests, including pointing to south, which tested their absolute frame of   reference. The students pointed by moving a pointer attached to a 360 degree   protractor. Following are the absolute pointing error, in degrees, of the   participants.      Male   13 130 39 33 10   13 68 18 3 11   38 23 60 5 9   59 5 86 22 70   58 3 167 15 30   8 20 67 26 19      Female   14 8 20 3 138   122 78 69 111 3   128 31 18 35 111   109 36 27 32 35   12 27 8 3 80   91 68 66 176 15      At the 1% significance level, do the data   provide sufficient evidence to conclude that, on average, males have a better   sense of direction and in particular, a better frame of reference than   females? (note; x1=37.6, s1=38.5, x2==55.8, and s2 =48.3)
