Computer Lab 2c Use the Accidental Drug Death dataset to answer the questions. 1. Use Analyze → Distribution to create a histogram and calculate summary statistics for the quantitative variable Age. Make sure your histogram is vertical and has a probability axis. Paste your histogram and summary statistics below. 2. What is the mean and median of the age variable? The mean is 42.0234 and the median is 42 3. There is a categorical variable called sex which identifies the sex of the person. Use Graph Builder to do side by side box plots for age by sex including a 5-number summary for both. Paste this plot here:
4. How does the age of accidental drug deaths between the sexes differ? Use Shape, Outliers, Center, and Spread to answer this question. S – Looking at the shape of the graph they are similar, but the female box tends to be a little bit bigger. O – The female box has no outliers, but the male box has outliers in the upper age range of the group C – The female box would be symmetrical, but the male box would be slightly skewed to the right because of the outliers in the high end of the data set. S – The female has a bigger spread if the outliers are not brought into consideration, but if the outliers are considered, than the male box would have the larger spread.
