Question

part 2: true or false (7 questions)

write t for true, f for false.

1. a data table only needs one column to be complete.
2. every formal graph must have a clear title and labeled axes.
3. we arrange data from smallest to largest to find the median.
4. x-axis = dependent variable; y-axis = independent variable.
5. each graph axis can have its own different scale.
6. a nonlinear relationship forms a straight line on a graph.
7. a data table is used to organize numbers and experimental data.

Explanation:

Analyze data table columns

Using the Data Tables knowledge point.
A complete data table needs at least two columns to show relationships.
Therefore, statement 1 is false.

Analyze graph requirements

Using the Graphing Data knowledge point.
Every formal graph requires a clear title and labeled axes.
Therefore, statement 2 is true.

Analyze median calculation

Using the Measures of Center knowledge point.
Finding the median requires ordering data from smallest to largest.
Therefore, statement 3 is true.

Analyze graph axes variables

Using the Scientific Variables and Graphing Data knowledge points.
The x-axis represents the independent variable, and the y-axis represents the dependent variable.
Therefore, statement 4 is false.

Analyze graph axis scales

Using the Graphing Data knowledge point.
Each axis on a graph can have its own distinct scale.
Therefore, statement 5 is true.

Analyze nonlinear relationships

A nonlinear relationship forms a curved line, not a straight line.
Therefore, statement 6 is false.

Analyze data table purpose

Using the Data Tables knowledge point.
Data tables are designed to organize numbers and experimental data.
Therefore, statement 7 is true.
