VocabularyVertical Axis: The up-down line on the left side of a graph. Has numbers that allow us to identify the graphs purpose
Horizontal Axis: The left-right line on the bottom of the graph. Has data/information that helps us identify the graphs purpose |
Today's Target: Be able to read a graph, and find out the mean, median, mode, range of the graph.
|
Reminder
- Mean: The averaged number of all numbers. Add all the numbers together then divide by the total amount of numbers used.
- Median: The middle number. Arrange the numbers in ascending, least to greatest, and the number in the center is the median. If two numbers are in the center, add them up and divide by 2.
- Mode: The number that appears most often.
- Range: The largest number minus the smallest number
Reading a Graph
Below is a graph on "Spelling Words Practiced." Over the course of the week, students practiced the listed words. When reading a graph, we need to look at both the horizontal axis (the days of the week) and the vertical axis (words practiced)
|
Thursday: 60 words practiced
Friday: 25 words practiced Saturday: 15 words practiced |

Together - Pie Graph
We will walk through this pie graph together.
Pie Graphs are unique because they always represent 100% of something. In the case below, it is 100% of cookies eaten.
