Imagine that we gave 100 individuals this short experiment and collected the differences between times in the incongruent & congruent condition. You want to know if men and women differed on this time between conditions. The data from these 50 men and 50 women can be found here: What is my null and alternative hypotheses? Is this a one or two-tailed hypothesis? Did I calculate the right statistical test? Why can I reject the null hypothesis or why not? can you help me with the descriptive statistics the type of test and reading the results including effect size and confidence intervals?

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.
