Qualitative data values categorized by traits that do not take a numerical value Quantitative data values that are measured Histogram graph of distribution of outcomes for a single numerical variable Outlier individual whose variable value falls outside of the overall pattern; outside 3 standard deviations Skewed Left longer tail of histogram is on the left side, most data is on the right Skewed Right longer tail of histogram is on the right side, most da...

To describe categorical data... correct answer: Make a picture. Bar graphs or pie charts work well. Summarize the distribution with a table of counts or relative frequencies (percents) in each category. Compare distributions with plots side by side. Interpret Standard Deviation correct answer: Standard deviation measures spread by giving the "typical" or "average" distance that the observations (context) are away from their (context) mean. Outlier Rule correct answer: Upper Bound ...

3.1 A histogram of a set of data indicates that the distribution of the data is skewed right. Which measure of central tendency will likely be larger, the mean or the median? Why? Choose the correct answer below. A. The mean will likely be larger because the extreme values in the left tail tend to pull the mean in the opposite direction of the tail. B. The median will likely be larger because the extreme values in the right tail tend to pull the median in the direction of the tail. C. ...
