Question

Sociodemographic differences in lung cancer worry. Hahn (2017) evaluated socio-demographic differences in how people worry about lung cancer. Some of the differences observed across demographics of interest were between males and females [t(45) = 0.69; higher mean worry among men], smokers and nonsmokers [t(45) = 2.69; higher worry among smokers], and whether or not a person graduated high school [t(45) = 2.56; higher mean worry among those who did not graduate high school]. However, at least one of these results were not statistically significant. Which test(s) was (were) not significant?

Answer 1

The result for the difference in lung cancer worry between males and females was not statistically significant in Hahn's (2017) study (t(45)=0.69, p > 0.05). The results for the differences in worry between smokers and nonsmokers, and those who did and did not graduate high school, were statistically significant with p values less than 0.05.
