Pardon me if this question does not fit this site (or SE engine in general) but I do not know where to post it. Suppose that you have unknown data set which you want to explore. What functions/methods/techniques should I use to get birds eye of the data? I guess it depends on the data. I'm particularly interests in the ordered integers (but feel free to post other types also). Few examples that comes to my mind are: histograms, barplots, (moving) mean (aka average) median mode variance standard-deviation. What else? Thank you.

  • $\begingroup$ @MaartenBuis thanks for reply. I've expected such answer therefore I'm asking for birds view. Can you recommend e.g. some literature ? $\endgroup$ – Wakan Tanka Mar 29 '16 at 20:37
  • $\begingroup$ This is a broad question: it would seem to require entire books to answer. I dislike the duplicate thread (because the answers focus on graphical techniques rather than on EDA per se), but it looks like exactly the question you are asking. $\endgroup$ – whuber Mar 29 '16 at 20:37
  • $\begingroup$ @whuber hmm seems that the linked question is mainly dealing with problems related to visualization. $\endgroup$ – Wakan Tanka Mar 29 '16 at 20:56
