Dear Sai Krishna Gudi it helps you to detect the median value quickly, the min and the max values ad also quartiles distributions.

I was just finalising my lesson for next week and taking inspiration from your question I made ad additional slide (So you will be on my slides for ever... ahaha!). I hope you appreciate. Please let me know otherwise.

This web link also can be helpful.

Hello A. M. Abdallah,

Thanks for that, I appreciate your efforts in answering my question.

Dear @Exal García-Carrillo I did this with PRISM 7 for mac. No idea if the software allows you to point out outliers (I'll check).

Maybe with SPSS or STATISTICA or STATA or R software, you will get what you are looking for. Anyway, you have already the min and the max values, so in general, you can dimension the phenomena. For clarity, I retain is more appropriate to link outliers with a simple column bar graph (mean with SD or SEM).
