Which of the following statements are correct?Question 8Select one or more:a.By convention, the dependent variable is usually plotted on the vertical axis.b.The dependent variable must always be plotted on the horizontal axis.c.The axis on which we usually plot the dependent / independent variable is determined by convention. However, this convention may be overridden by other graphing conventions.d.By convention, the dependent variable is usually plotted on the horizontal axis.e.The variable which we choose / control the values of, is usually plotted on the vertical axis.f.Historically, the vertical axis was sometimes known as the abscissa.

Is the dependent variable placed on the x-axis or y-axis when drawing a graph to show the relationship between two variables?Question 3Answera.y-axisb.x-axis

Is the horizontal axis an independent or dependent variable in the plot, and is the number axis an independent or dependent variable

Which one of the following is NOT TRUE for graphical representation of experimental data (on a regular graph paper)?Group of answer choicesA best-fit line is drawn if possibleDependent variable is plotted in y-axis (vertical axis) and independent variable is plotted along x-axis (horizontal)Vertical and Horizontal scale must be the sameAttempt should be made to use the maximum graph area possibleVertical and Horizontal scale can be different

2. The graphs below show the same data but with different fiUed curves. Published datasuggests that the rela?onship between the dependent and independent variables is bestdescribed by a linear equa?on.Which two (2) of the following statements about these graphs are INCORRECT?A. FiUed equa?on B is the best because it has the highest R 2 value.B. The fiUed equa?ons should not be forced through 0,0 as we have no data for this.C. FiUed equa?ons A and B must be beUer as these conform to the theore?calrela?onship between the variables.D. FiUed equa?on A has a R2 value under 0.8 so it must not be used.E. There is no jus?fica?on to use the non-linear fits in C and D.

Graph the line that passes through the coordinates shown and determine which statement is true. A. The line that passes through the given coordinates represents a proportional relationship because the line passes through the origin. B. The line that passes through the given coordinates does not represent a proportional relationship because the line passes through the origin. C. The line that passes through the given coordinates does not represent a proportional relationship because the line does not pass through the origin. D. The line that passes through the given coordinates represents a proportional relationship because the line does not pass through the origin.
