To find out if there are any outliers, I first have to find the IQR. There are fifteen data points, so the median will be at position (15 + 1) Ã· 2 = 8. Then Q 2 = 14.6. There are seven data points on either side of the median, so Q 1 is the fourth value in the list and Q 3 is the twelfth: Q 1 = 14.4 and Q 3 = 14.9.o find out if there are any outliers, I first have to find the IQR.

Message broker. In computer programming, a message broker is an intermediary program module that translates a message from the formal messaging protocol of the sender to the formal messaging protocol of the receiver.
1 MQTT-S Overview â¢ Designed to be very similar to MQTT. - i.e. Use MQTT Semamtics â¢ Clients are WSN nodes, which communicate via a Gateway to a Broker on IP network. â¢ 2  The Gateway may just translate messages between MQTT-S and MQTT, so the broker is a normal MQTT broker. â¢ The Gateway may just translate messages between MQTT-S and MQTT, so the broker is a normal MQTT broker. â¢ 2  Designed to work on any WSN Architecture/transport.
