A visual representation of the five number summary.
Box plot
A line graph depicting a set of data that are normally distributed; meaning the frequency values are highest in the middle, and the graph is symmetric.
Normal curve
The square of the average distance from the mean. Tells how spread out the data is.
Standard deviation
The difference in the numbers of a data set
Variation
Used to show the relationship between two data sets.
Scatter plot
Used to show each value in a data set and to group values into intervals. Allows to pull out the data from the graph.
Stem and leaf
Used to show the division of a whole into parts.
Circle graph
Used to compare numbers of data items grouped in numerical intervals
Histogram
Used to compare numbers of data items grouped in categories; order does not matter except for convenience.
Bar graph
Used when there is only one group of data with less than 50 values.
Line Plot
Used to show how the data values change over time; normally used for continuous data.
Line graph
If all things are equal, everyone will get the same amount.
Mean
The data value that occurs most often.
Mode
The middle data value.
Median
The set of objects in which position, or order, matters.
Permutation
The set of all possible outcomes.
Sample space
An event that is not likely to happen.
Impossible event
The set of objects in which position, or order, does not matter.
Combination
A numerical value that represents the degree to which we believe that an event will or will not happen.
