What are Individuals?
The main features of a distribution. Often described as symmetrical or skewed
What is the shape?
Shows each value as a dot above its location on a number line
What is a Dotplot?
Any attribute that can take difference values for different individuals
What is a Variable?
Tells how much variability there is in the distribution
What is the spread?
Shows each category as a bar. The heights of the bars show the category frequencies or relative frequencies
What is a Bar Chart? (Bar Graph is also acceptable)
Takes number values that are quantities - counts or measurements
What is a Quantitative Variable?

What is the center?
Shows the proportion or percent of individuals having each data value
What is a Relative Frequency Table?
Takes values that are labels, which place each individual into a particular group, called a category
What is a Categorial Variable?
An individual that falls outside of the overall pattern
What is an outlier?
Shows each data value separated into two parts: a stem, which consists of all but the final digit, and a leaf, the final digit
What is a Stemplot?
Tells us what values the variable takes and how often it takes these values
What is Distribution?
A way of describing the shape of a distribution when there are more individuals on one side.
What is skewed?
