[Math] book recommendation on data analysis and statistics

Question

I am looking for a book on data analysis and statistics.

My objective is to better analyse and understand data over time (like trends or events) and extract useful information from raw statistics. I am not especially interested in forecasting.

Any recommendations?

Answer 1

An oldie but goody is John Tukey's book Exploratory Data Analysis. It won't tell you everything you need to know, but it has some good basic content.
