A data set from a study that examined the effect of a specific
diet
on
blood pressure
is provided . Participants (n
= 72) were randomly assigned either to a group that was put on the diet (Diet = Present) or to a group that was not put on the diet (Diet = Absent), and researchers wanted to know whether the diet had a significant impact on blood pressure.

Fully

the results in the context of this study (i.e., report the conclusions as related to the research question).

The denominator used in estimating the effect sizes. Cohen's d uses the pooled standard deviation. Hedges' correction uses the pooled standard deviation, plus a correction factor. Glass's delta uses the sample standard deviation of the control group.
