Edexcel and I'm really nervous that's why am double checking everything 😭 Also I covered the whole course but I still get questions wrong and I think it's the wording
It isn't but it should be a reference point to where the pattern of the bell shape should end and start (flatten out). My teacher said that they would be precisely seeing if your graph is correct, but they will see if the graph flattens our at the correct point.

Can someone please help me on distribution of standard deviation graphs? Like when it's normal and percentages and things? And also when to use each formula and it's just all so confusing, and how it overlaps with the mean? Would be much appreciated x

Normal distribution is a bell shape line. Below that it is like the population.
68% of population is covered by SD 1/-1 95% is covered by SD 2/-2 99% is covered by SD 3/-3
