This *beginner* level data set has 2000 rows and 8 columns.
The data set contains wifi signal strength observed from 7 wifi devices on a smartphone collected in indoor space. 
The data could be used to estimate the location in one of the four rooms.

This data set is recommended for learning and practicing your skills in **exploratory data analysis**, **data visualization**, and **classification modelling techniques**. 
Feel free to explore the data set with multiple **supervised** and **unsupervised** learning techniques. The Following data dictionary gives more details on this data set:
