| A graph using vertical and horizontal bars to display data. | bar graph |
| The sum of the items in a set of data divided by the number of items in the data set; also called the average. | mean |
| A graph in which line segments show changes in data, often over time. | line graph |
| A bar graph that shows the frequency of numerical data within equal intervals. | histogram |
| A graph that uses sections of a circle to compare parts to the whole and parts to other parts. | circle graph |
| The middle number, of the mean (average) of the two middle numbers in an ordered set of data. | median |
| A number line with marks or dots that show frequency of data. | line plot |
| The difference between the greatest and least values in a data set. | range |
| The vertical line (up & down) on a coordinate plane. | y-axis |
| The horizontal line (left & right) on a coordinate plane. | x-axis |
| A graph that uses symbols or pictures to graphically represent data. | pictograph |
| The number or numbers that occur most frequently in a set of data. | mode |
| A table that lists items together according to the number of times, or frequency, that the items occur. | frequency table |
| The amount of space between the values on a number line or scale of a graph. | interval |
| A value much smaller or larger than the rest in a data set. | outlier |
| A plane containing two perpendicular axes (x and y) intersecting at a point called the origin (0,0) | coordinate plane |
| Shows a point on a coordinate plane. The x-value is first, then the y-value. (x,y) | ordered pair |
