Means for groups in homogeneous subsets are displayed.
a. Uses Harmonic Mean Sample Size = 125.690.
b. The group sizes are unequal. The harmonic mean of the group sizes is used. Type I error levels are not guaranteed.
Compare and contrast the means of three or more groups. Are households with more children more likely OR less likely to recommend their favorite Mexican restaurant than are households with fewer children? You must explain what the numbers tell the managers. In other words, as a management consultant what are the research findings or conclusions. Explain fully your conclusion. Don't guess. Support your answer by providing the mean that was computed.

Explanation / Answer
to compare more than two variables we can conduct a F-test to see if there is a difference in the three scores of the famlies with few and more children.
while in the comparisions table we see there is a significant difference in mean scores of families with no children when compared with families with more than 0 children while when we further go through the table we see that this relationship does not hold true when we compare families with 1-2 children with more than 2 children families.
