Means, Standard Deviation and Broken line plot

I wish to calculate the mean/standard deviation of a single column in the excel file that will be created at the end of my task, as well as create a broken line plot (instead of the stairs you can see in the code). I'm currently using PsyToolBox.

Here is the little i've figured out so far:

T = readtable('Test.xlsx')
summary(T);
Avg = mean(T,1);
figure
stairs(T.RT)
grid

No idea what the PsyToolBox contains that matters and not sure what you mean by a "broken line" plot?

Sorry, i believe i have the incorrect english term but here's what i meant!

That's what you'll get by

plot(T.RT,'-.',markersize',10)

See the doc for plot function for details of line style, etc., ...

Sweet! Thank you! Do you know how i could do the "summary(T)" part, but with the mean and SD instead of just min/max/median?

grpstats is probably most convenient way to return a plethora of statistics -- but it requires a grouping variable so to do the whold dataset will need to introduce a constant to serve the purpose

stats=grpstats(T,ones(height(T),1));

If there are nonnumeric variables in the table, then will have to specify whch are numeric with the optional 'DataVars' named parameter. You select the statistics desired with a cell array to specify multiple types of summary statistics.

See the doc for details, examples of use. Requires the Statistics Toolbox
