) Compute the proportion of variance using omega-squared. (b) Suppose the pooled sample standard deviation for this test is 0.74. Using this value, compute estimated Cohen's d.
Sociodemographic differences in lung cancer worry. Hahn (2017) evaluated sociodemographic differences in how people worry about lung cancer. Some of the differences observed across demographic of interest were between males and females [t[45]=0.69; higher mean worry among men], smokers and nonsmokers [t[45]=2.69; higher mean worry among smokers]. However, at least one of these results were not statistically significant. Use the information provided to state which t test or t test did not reach the .05 level of significance in this study.
(a) Compute the proportion of variance using omega-squared.
