Question | Answer |
offers a short explanation of what is in your graph. This helps the reader identify what they are about to look at. | Graph Title |
In line graphs, the __axis runs horizontally (flat). Typically, this axis has numbers representing different time periods or names of things being compared. | X-Axis Label |
In line graphs, the __axis runs vertically (up and down). Typically, this axis has numbers for the amount of stuff being measured. | Y-Axis |
explains where you found the information that is in your graph. It is important to give credit to those who collected your data! | Source |
defines the number of items and groups of items | Data set |
tells what each line represents. Just like on a map, the legend helps the reader understand what they are looking at. | Legend |
the information contained in the graph | Data |
are used to track changes over short and long periods of time. | Line Graph |
are best to use when you are trying to compare parts of a whole. They do not show changes over time. | Pie Chart |
are used to compare things between different groups or to track changes over time. | Bar Graph |
are used to determine relationships between the two different things. The x-axis is used to measure one event (or variable) and the y-axis is used to measure the other. | X-Y Plot |
an object, event, idea, feeling, time period, or any other type of category you are trying to measure. | Variable |
The steepness of a line expressed as a ratio, using any two points on the line. | Slope |
standing upright at a right angle to the horizon | Vertical |
parallel to the horizon; goes across | Horizontal |
the pattern of values that makes up one axis on a graph | Scale |
| Axis |
the difference between the least and greatest values in the set | Range |
a way to organize data that allows you to easily see patterns and relationships | Table |
the value or values that occur most often | Mode |
a pair of numbers (x,y) used to locate a point on a coordinate grid | Ordered pair |
the gap between the numerical values of one axis on a graph | Interval |
tells the number of times an event, category or group occurs | Frequency table |
the sum of all the items divided by the number of items in the set | Mean |
