Question
Well I have this graph to plot for an experiment that we did today in class.Let me list out the steps for you.
1) Hold a metre rule vertically with the lower end touching the subject's open hand.Here the subject can both see and touch the ruler.
2) tell them that you will be letting the ruler fall soon and that they must catch it as quickly as possible.
3) Wait a few seconds then let go of the ruler
4) Record the distance the ruler has fallen.
5) Repeat steps 1-4 ten times using variable lengths of time before you drop the ruler.
6) Repeat the whole exercise this time with the ruler visible to the subject but not touching the subject's hand.
7) Finally repeat the exercise with the ruler touching the subject's hand but ask the subject to close their eyes.
8) Calculate the mean distance the ruler has fallen under the 3 conditions and plot a bar graph of the results obtained.

Can you please tell me how to plot that bar graph? Which results do I use?

Answer
On the vertical axis  plot the units of measure (mean distance= average of tries)
On the horizontal axis plot the three conditions

   8            top of bar

   6 Top of bar

cm  4

   2
                                 top of bar
   o

        cond 1        cond 2        cond   3

 Of course I just made up numbers.
