Julie does a nice job showing how to find the standard deviation of the data set. Her introduction gave the viewer time to mentally prepare for the problem. The bubbles were helpful and complimented what she was saying helping to clarify the work. She was very clear in explaining the steps to take. I like that she showed us how to use square root on a calculator. I also liked how she told us to round as stated in the problem; perhaps it would have been helpful to have referred back to the problem telling to round to the nearest tenth so as to be clear on why she rounded and to which place. Overall, great video!
