Terms in this Study Set(24)
What is a data graph?
A visual representation of information, showing relationships between variables.
Types of graphs on the SAT
Bar graphs, line graphs, pie charts, and tables are commonly used.
True or false: Graphs always have a title.
True, because a title indicates what the graph represents.
Function of the x-axis
Represents the independent variable in a graph.
Function of the y-axis
Represents the dependent variable in a graph.
Difference between pie chart and bar graph
Pie charts show parts of a whole, while bar graphs compare quantities.
What is a line graph?
A graph that uses points connected by lines to show trends over time.
Fill in the blank: The area of a pie chart represents _____
The proportion of each category to the whole.
What do bar graphs compare?
Bar graphs compare different categories of data.
True or false: Line graphs can represent non-linear data.
False, because line graphs typically show linear relationships.
Interpret the slope in a line graph
The slope indicates the rate of change between variables.
What is a trend line?
A line that best represents the data points in a graph.
True or false: Axes must be labeled.
True, because labels clarify the data being presented.
Bar graph vs. histogram
Bar graphs use spaces between bars; histograms do not.
What does a legend in a graph do?
It explains the symbols or colors used in the graph.
Which axis usually shows time?
The x-axis typically represents time in graphs.
What is a scatter plot?
A graph that displays values for typically two variables for a set of data.
Identify the dependent variable
The variable that responds to changes in the independent variable.
Fill in the blank: The scale on a graph must be _____
Consistent to accurately represent data.
True or false: Graphs can mislead if poorly designed.
True, because unclear graphs can distort data interpretation.
What is the purpose of a graph title?
To summarize the main idea or data being represented.
Difference between qualitative and quantitative data
Qualitative data describes characteristics; quantitative data includes numbers.
What does a steep slope indicate?
A steep slope shows a rapid change in the dependent variable.
What is a categorical variable?
A variable that can be divided into categories but not measured numerically.
