Data science algorithms can be applied in a wide range of fields – whether for customer profiling or medical diagnosis, these algorithms can give you key insights to help you make more strategic decisions.

**What do others have to say?**

"... Having been familiar with the work of Annalyn Ng and Kenneth Soo for some time, it comes as no surprise that the book delivers on its titular promise. This

isdata science for the layman, and the often-complex math -- which the book describes at a high level -- is intentionally not covered in detail. But don't be misled: this does not mean that the contents are in any way watered down. In fact, the information contained within is robust, with its strength being that it is abridged and concise."
