Draw the distribution of the number of the WAPs that are detected on a single capture.
Draw the distribution of RSSI value that are detected (eliminate RSSI=0).
Draw the distribution of the (1)mean、median and (2)standard deviation of each WAP.
Use the data of the WAP with the lowest mean (you can get it from Q3), and draw its PDF and CDF of the RSSI distribution of different buildings (BUILDINGID 0~2). (you should compare the difference between three building and write your discoveries)
