probability plot analysis

[computron9000]

Hey guys.

Would you say this probability plot shows normal distribution?
I thought it did, because they all pretty much follow the line, or is that slight bit of difference enough to deem it not normal?

Also when talking about the outlier of 4pin is that enough to deem it not normal?

Any help appreciated
Thank you!

P.s there are 20 values from each level plotted, 100 in total.

oops forgot to include this haha.

Ive written this

"For normal distribution, we can see in the probability plot that all the values follow the straight line quite well (apart from one outlier on the 4pin results). There is very slight variance from the line in the 3 pin and control plots, but because it follows it so closely we can say that our data is normally distributed. "

Any critique would be appreciated.
Thanks

I am not familiar with this type of graph, what is going on with it?
