Answer:
When describing data, always start with a graphical representation.
Graphs help identify the overall distribution pattern. Looking at a graph
makes it visually clear how spread a variable is, which values occur most
frequently, and whether or not the distribution is skewed.
Next, obtain more precise information by providing a numerical summary of
the data using the mean, median, range, five-number summary, and any
other appropriate information.
Some distributions are so regular that they can be described by a smooth
curve. Real data are represented in a histogram. Curves represent a symbol,
or an abstract version of a distribution.
