what is a graph and why do we use them?
define these: bar graph, pie chart, line graph |
|
Definition
a visual display of data; they are important because they help us compare data to each other
bar graph:each bar represents a number counted at a specific point in time; good for counting
pie chart: shows how a fixed number gets broken down into sections
line graph: shows the relationship between the independent and dependent variables |
