I answered the 5 questions, i just need help with the next couple of questions

6. Calculate the measures of variability (range, IQR, ) for each group. Show your work using the Raw Score formula for but ALSO calculate using the deviation formula to make sure your answer is the same for both. 7. Construct a boxplot for each group on the same graph (see Figure 5.3 in the text) 8. describe the number of sugary drinks each group drank. 9. Calculate the effect size (d) of the difference between the two groups, assuming = 2.60
