I have a question when they ask to plot a graph and it's not a bar graph and the points are scattered or not in a line to we make a line of best fit or a curve I've even seen sum mark schemes which say join each point with ruled out line while sum say curve or best fit
So how do we decide?

when the points are just scattered around then u make a line of best fit but when they are in some order like their path is curving then u make a curve and in that also some times one point will be displaced so u will hav to leave that point :)
