Question 2ci) It says plot p against 1/h. That means we plot p on the y-axis and 1/h on the x-axis right? But isn't p the independent variable here? We plot the independent variable on the x-axis right?
But 2)a) reads "A graph is plotted with p on the y-axis and 1/h on the axis".
They also want us to plot the error bars for 1/h , but if 1/h is on the x-axis, won't the error bars be parallel to the x-axis (horizontal). But the markscheme says "Should pass from top of top error bar to
bottom of bottom error bar". How would you find the "top" of the top error bar, if it's horizontal? Theres no top/bottom to a horizontal error bar is there?
What do they really want us to do? Please help me out guyz.
