On Friday, 29 students in Ms On Friday, 29 students in Ms. Skelton’s 6th period conducted a simulation to calculate the average outcome of a six-sided dice. Here’s the result: 3.98 3.66 3.72 3.46 3.16 3.48 3.48 3.42 3.42 3.28 3.76 3.34 3.48 3.50 3.98 3.60 3.58 3.85 2.92 3.64 3.13 3.74 3.92 3.38 3.90 2.96 3.44 3.39 3.72 Construct a stemplot of the data. Be sure to include a title and key. What are the mean, median, mode, and range of the values displayed on your plot. Briefly comment on the shape of the stemplot as a result of the difference between mean and median.
Right skewed shape: Median < Mean Symmetric: Median = Mean (or roughly the same) Left skewed shape: Median > Mean New Slide: Insert Figure 3.1 CFU: Begin with a symmetrical shape, what happened if: a “very small” value is added a “very big” value is added left skewed shape right skewed shape
