CAVA Chem: Graphing
Graphing Lesson from CAVA Chemistry
| Question | Answer |
|---|---|
| Graphs show relationships between [...]. | Graphs show relationships between variables. |
| When you plot the volume of the gas against the temperature, the line of the graph shows the relationship between the two variables, temperature and volume. Temperature is on the [...] and volume is on the [...]. | When you plot the volume of the gas against the temperature, the line of the graph shows the relationship between the two variables, temperature and volume. Temperature is on the x-axis and volume is on the y-axis. |
| When you plot One thing 'against' another, the one thing goes on the [...] and the other thing goes on the [...]... that's the (arbitrary) convention (don't blame me, it's not my fault). | When you plot One thing 'against' another, the one thing goes on the y-axis and the other thing goes on the x-axis... that's the (arbitrary) convention (don't blame me, it's not my fault). |
| If the graph of one variable against another shows a straight line, the two have a [...] relationship. | If the graph of one variable against another shows a straight line, the two have a linear relationship. |
| [...]-axis: the bottom of the graph... measures side-to-side | x-axis: the bottom of the graph... measures side-to-side |
| [...]-axis: the left side of the graph... measures up-and-down | y-axis: the left side of the graph... measures up-and-down |
| The independent variable is (by convention) placed on the [...]-axis | The independent variable is (by convention) placed on the x-axis |
| The dependant variable is (by convention) placed on the [...]-axis | The dependant variable is (by convention) placed on the y-axis |
| A [...] line shows the relationship between the independent and dependent variables. | A trend line shows the relationship between the independent and dependent variables. |
| When you draw a trend line, you don't try to connect the dots. You draw a line that shows the [...] of your data points. | When you draw a trend line, you don't try to connect the dots. You draw a line that shows the general trend of your data points. |
| The slope of a line is the [...] divided by the [...] between two points on the line. | The slope of a line is the change in y values divided by the change in x values between two points on the line. |
| If the graph of one variable plotted against another is not a straight line, they have a [...] relationship. | If the graph of one variable plotted against another is non a straight line, they have a non-linear relationship. |
| If one variable increases as the other one also increases, they have a [...] relationship. | If one variable increases as the other one also increases, they have a direct relationship. |
| If one variable decreases as the other one increases, they have an [...] relationship. | If one variable decreases as the other one increases, they have an indirect relationship. |
