Instructions: i'm going to go easy on you for this one! We learned a iot about the tTest for independent samples, and last week you compared estimated speed fin miles}! for smashed in to group and hit group. This week, i want you to review that assignment and NOW compute the effect size {Cohen's D using the pooied variance]. To make sure you have ali the data you Pl need to calculate the effect size, here are the means and standard deviations for the "hit" and "smashed into" groups from last week. Group #1: Smashed into mean and SD: Mean = 44.5, Variance = 33.42. SD = 5.?3 Group #2: Hit mean and SD: M = 30.?,Variance = 27.11, SD = 5.212 D Question 1 2 pts Compute the effect size [Cohen's d using the pooled variance}. Which of the following is the effect size? Round 2 decimal points. 0 Cohen's d =1.13 O Cohen's d =2.10 O Cohen's d =1.12 O Cohen's d =2.50 D Question 2 2 pts What does the pooled Cohen's d you obtained using the coin study data represent? O A small/weak effect O A medium/moderate effect O No effect O A large effectD Question 3 2 pts What is the effect size and why do we report it?
