participant's score on the "Self -Concept Clarity " scale , which is a scale that measures a person's level of clarity about their identity (ever remember being confused about who you really were as a teenager ? It's that...). Incidentally, the SCC scores can range from 12-60, and higher scores indicate more confusion n or uncertainty about the self . The Group variable is derived from the participant's ages : 11 year -olds are group 1, 14-16 year olds are group 2, and 17-18 year olds are group 3. Please p produce an error bar graph showing the 95 % CI for all groups . Look at the results , and think about whether you think there may be a statistically significant difference between the means of any of the age groups Next , run an independent samples t-test on groups 1 and 3 to determine whether older teens (17- 18 year olds ) have a clearer concept of themselves than pre -teens (11 year olds ). Note that you will need to "define groups" when you run the t-test. 'Group 1' should be 1 (the 11 year olds), and 'Group 2' should be 3 (the 17-18 year olds). Upload a screen shot of your error bar graph , along with your t-test results into canvas . Then , answer the following questions Looking at your error bar graph Q 21.) Do the 95 % CI of the means for groups 1 and 2 overlap ? Q22 .) Do the 95 % CI of the means 1 and 3 overlap ? Q23 .) Do the 95 % CI of the means 2 and 3 overlap ? Q24.) What is the N of SCC scores for 11 year-olds? Q25 .) What is the Mean of SCC scores for 11 year -olds ? Q26 .) What is the Standard Error of the mean of SCC scores for 11 year -olds ? Q 27 .) What is the N of SCC scores for 17-18 year olds ? Q28 .) What is the Mean of SCC scores for 17 -18 year olds ? Q29 .) What is the Standard Error of the Mean of SCC scores for 17-18 year olds ? Using Equal variances assumed , report the results of your t-test : t(?)=?, p=? Q30 .) t(?) Q31 .) t(_)=? Q32 .) t(_ )=_ , P=? Q 33.) What is the raw effect size of your data ? (Mean Difference score )? Q34 .) What is the lower bound of the 95 % CI of the difference between the means ? ? SH - M, =. Q35 .) What is the upper bound of the 95 % CI of the difference between the means ? - SH, - H, s ? Q36 ). Based on the results of the t-test, what can you conclude ? Mark all 3 that apply . We can reject Ho We cannot reject Ho The difference between the means is statistically significant The difference between the means is not statistically significant Older teens have different self -concept clarity than pre -teen children We cannot tell whether the self-concept clarity of older teens is different than pre-teens
