Tonight please complete #'s 1-3 (completely) on the Quiz A--Chapter 5 worksheet provided in class.
Here are a few tips:
1a. If you need help with the histogram (by hand and on your calculator), use the TI Tips in the yellow box in your textbook (for calculator help!) Histograms are in chapter 4.
1d. Look at the shape of the histogram! If it's skewed, we use median and IQR. If symmetric, we prefer the mean and standard deviation.
2a...Think!
2b. Calculate the "fences" we discussed today in class to find the boundaries for outliers.
