Interpret Graphs

 * Line Graph ** - A graph that shows points connected by lines to show how something changes in value. [|About Line Graphs]

**Bar Graph**- A graph drawn using rectangular bars to show how large each value is. [|About Bar Graphs]

** Pictogragh- ** a graph that uses small pictures to represent something. [|About Pictographs]

**Circle Graph**- A circle that is divided into sections, with each sections representing a part of a set of data. (Also called a pie chart.) [|About Circle Graphs] = Plots and Diagrams = **Box and Whisker-** a graph that summarizes a data set along a number line.There is a box in the middle and whiskers on either side. Example: = Measures of Central Tendency =
 * Stem and Leaf Plot**- A plot where each data is split into a "stem" and "leaf." Stem being the first digit and leaf being the second digit.

**Median**- the middle value of the numbers arranged in order **Mode**- the number that occurs most often in a set of data **Outlier**- a number much higher or lower in a set of data in a set **Range**- the difference between the greatest and smallest data value [|Help] [|Tutorial]
 * Mean(Average)- ** sum of the data divided by the total number of data items

= Probablity = **Probability**- The probability that an event is likely to occur **Outcome**- the result of a single trial **Sample Space**- all of the possible outcomes **Experimental Probability**- number of times an event occurs over the number of times the experiment is done **Theoretical Probability**- number of favorable outcomes over the number of possible outcomes **Event**- any outcomes or group of outcomes [|More about Data and Probability] [|Try some probability games!]
