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.
