Independent events
Two events that have no effect on the outcome of the other. For example, tossing a coin and rolling a die are independent events.
Line plot
A frequency table that uses the number line to display the data.
Bar graph
Graph that is used when you want to compare amounts to each other.
Frequency table
Chart that shows items and the number of times they occur.
Mean
The sum of the data divided by the number of addends.
Box and whisker
Plot that shows how data is distributed. It shows the high and low scores, median, and quartiles.
Line graph
The graph you would use to show changes over a time period.
Theoretical probablility
The likelihood an event will occur based on the number of possibles outcome. The ratio of the number of favorable outcomes to the number of possible outcomes.
Permutation
An arrangement in a particular order. The digits 1,2,and 3 would be arranged as 123,132,213,231,312,321.
Counting principle
The number of outcomes for an event with two or more distinct stages is the product of the number of outcomes at each stage.
Circle graph
Graph that is used to compare an amount to the whole.
Experimental probability
How likely an event is, based on collected data. For example: Number of 3s thrown/number of tosses.
Range
The difference between the highest and lowest items in a set of numerical data.
Median
The middle number when a set of numerical data is displayed in numerical order. There are just as many numbers higher than this number as there are lower.
Random sample
Subgroup selected at random from a population.
Database
An electronic spreadsheet in which information can be organized and reorganized for a variety of purposes.
Representative sample
Subgroup that has the same characteristics as the larger group.
Probability
Numerical term that describes how likely it is that an event will occur.
Mode
The item that appears most often in a set of data.
Frequency
How often an event or number occurs.
