[Eeglablist] Question about testing hypothesis

[Makoto Miyakoshi]

Dear Valerio,

> 1-Did you mean that I need to do some enhancement to the plot in order to
me more efficient for publication?

I definitely think so.

> 2- Did you mean each grayed column apply the p <0.05? What is the best
way to interpret the plot in this case? Should I say the 2 plots (center
and leftmost) are different in the latencies that are indicated by the gray
column?

Yes. Interpretation is not so easy if the significance area are scattered.

> 3- Should like this plot having such geayed columns get displayed in the
paper without having any associated data and information such mean and
standard deviation? What you could do when you might have like this plot?

There are standards for reporting data; mean, standard deviation,
statistics score, p-value, etc. See papers.

> 4- If I have plot with condition p <0.05, but all the areas are white
instead of having gray colour. Does that means that the condition is not
existed?
The differences are non-significant (which does not guarantee that there is
no difference).
