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