Hi all, I am trying to get the boxplot for Time (HH:MM:SS) and day name data but unable to get the required plot. In detail, I would like to get the Boxplot in terms of days, (Monday to Sunday). I have attached the sample data and any help in this regard is highly appreciated.

Yes, with numeric data, you can calculate medians and standard deviations. It looks like your data is a character array, meaning it is text. See Jonas' suggestion below.

i suggest to convert you time (Hour : Minute : Seconds) to seconds using
[~, ~, ~, H, MN, S]=datevec('14:35:22','HH:MM:SS');
MN=MN+60*H;
S=S+MN*60;
then doing you boxplot thing and then converting your boxplot y labels back to a timestring
