13 April (Dot DiagramTask): Hottest month in Singapore 2010

In a travel guide about Singapore, it was highlighted that "The temperature hovers around a diurnal range of a minimum of 23 °C (73.4 °F) and a maximum of 31 °C (87.8 °F). June is the hottest month of the year in Singapore, followed by May."

However, in 2010, February was reported to be the driest month. 


Let's do a comparison using the dot diagram, to compare the temperature in February 2010 and June 2010.

Below is the dot diagram that represents the maximum temperature of each day recorded in June 2010.
What are the mode, mean and median temperature of June 2010?
