In a random sample of 33 junior executives, each is classified by potential for promotion
as good, poor, or uncertain. Each is given a test to measure his or her level of anxiety.
The coded results (the higher the value the higher the level of anxiety) are as follows:
Good 4 5 4 3 2 5 3 2 5 4 4 4 3
Poor 4 8 7 5 5 4 9 9 6 7

Suppose that a golf association wants to compare the mean distances travelled by four
different brands (A, B, C and D) of golf balls when struck with a driver. A randomised
block design is employed utilising a random sample of 8 golfers, with each golfer using a
driver to hit four balls one from each brand in a random order. The distance travelled is
to be recorded for each hit.
(a)
Why is a randomised block design employed and why is randomisation necessary?
(b) The experiment was carried out as designed but the results were erroneously analysed
as if the experiment had been completely randomized (i.e. no blocking) with the oneway
ANOVA output given below. Based on this output, is there evidence that the
mean distances associated with the brands differ?
(c)
Suppose the sum of squares due to the golfers is 4264. Set up the ANOVA table that
will incorporate this information. Is the conclusion the same as that in (b)?

(a) Calculate the means for the four observations in each temperature-pressure group.
Plot the means of the nine groups on a graph with tensile strength on the y axis and
temperature on the x axis. For each pressure, connect the three points corresponding
to the different temperatures. What does the plot tell you regarding interaction and
main effects? [ Note that you can alternatively plot the nine points on a strength vs
pressure graph and for each temperature, connect the three points corresponding to
the different pressures.]
(b)
Run a two-way ANOVA on these data. Summarize the results of the significance
tests.
