Compas and others (1994) were surprised to find that young children under stress actually report fewer symptoms of anxiety and depression than we would expect. But they also no- ticed that their scores on a Lie Scale (a measure of the tendency to give socially desirable answers) were higher than expected. The population mean for the Lie scale on the Chil- dren’s Manifest Anxiety Scale (Reynolds and Richmond, 1978) is known to be 3.87. For a sample of 36 children under stress, Compas et al., found a sample mean of 4.39, with a standard deviation of 2.61. How would we test whether this group shows an increased tendency to give socially ac- ceptable answers? What would the null hypothesis and research hypothesis be? What can you conclude from the data?
