1.3Â Â Appendix: Making and Using Graphs 1) The horizontal axis in a graph A) measures time on a scatter diagram. B) measures the quality of a variable. C) is named the y-axis. D) is named the x-axis. E) is called the origin. 2) Most economic graphs have two lines perpendicular to each other. The vertical line is called the A) origin. B) y-axis. C) x-axis. D) variable. E) time axis. 3) The vertical axis in a graph A) is named the y-axis. B) is named the x-axis. C) measures time in a cross-section and time series graph. D) has no origin. E) measures time only in a time series graph. 4) Most economic graphs have two lines perpendicular to each other. Where these lines met is called the A) origin. B) y-axis. C) x-axis. D) variable. E) point of beginning. 5) A graph of the value of one variable against the value of another variable is known as a A) two-dimensional graph. B) three-dimensional graph. C) time-series graph. D) scatter diagram. E) two-variable graph. 6) A scatter diagram can be used to see A) if the value of a variable is rising or falling. B) the value of a variable for different groups in a population. C) if a relationship exists between two variables. D) how a variable behaves over time. E) whether a variable is positively or negatively related to itself. 7) To show how a variable ________, we typically use a ________. A) relates to another variable; time series graph B) relates to another variable; pie chart C) changes over time; time series graph D) changes over time; cross section graph E) changes over time; cross time chart 8) Which type of graph is most useful in determining if two variables are correlated? A) time-series B) scatter diagram C) cross-section D) variable-correlation figure E) None of the above answers is correct. 9) The figure above shows a A) time-series graph. B) scatter diagram. C) cross-section graph. D) slope. E) trend diagram 10) A time-series graph measures A) the value of one variable against the value of another variable. B) the value of an economic variable for different groups in a population at a point in time. C) time on the x-axis and the variable or variables in which we are interested on the y-axis. D) time on the y-axis and the variable or variables in which we are interested on the x-axis. E) time on both the x-axis and y-axis and the variable or variables in which we are interested in the rest of the figure.
