I will make a graph with 2 lines (2 sorts of flour, i n my case) in a graph.
On the y-as: The loafvolume
On the x-as: The % flour added to the recipe.
I have measured 5 times each point. Thus 5 measures of the loafvolume with 1 % flour a, en too with 3 and 5 %.
The same for the other flour.
Thus i have altime an error on my measure, and this error, will I see in the grafiek whit a sort of flag. Bu I d'ont now how I must make it.
Help me please?
