T-Mobile 9:24 AM 0 * 27% í D. omparing Variation: e following figures are from your lab handout. The means in all 3 graphs in gure 6 are the same. ? Group 1 values . Group 2 values low variabilty 0A Medium variability High variability Group 1 mean Group 2 mean Figure 5. The t-test Figure 6. t-test comparison of distributions Ift-tests were run to determine whether the two groups were significantly different than one another, which data set would be more likely to be significantly different (Low, Medium, or High variability)? Explain why

Explanation / Answer

Fig 6 conveys the information of the means and degree of variability of two groups (low, medium or high). It does not provide exact value of standard deviation or standard error of the data.
Fig 15 conveys the information of the means of two groups. In addition to this, the error bars in Fig 15 also provide information of one standard deviation of uncertainty or one standard error of the data for both the treatments (groups).
So, Fig 15 conveys more information about actual data set.
