През цялото време се говори за 'МАКСИМАЛНИТЕ' температури за деня!On. Jan 2, most temperatures across the province felt colder than -30 C with the wind-chill, and in some areas plummeted into the almost unfathomably freezing territory of-50 C.

In the afternoon of Jan. 2, Montreal was more than twice as cold as Iqaluit, Nunavut.
Many record cold temperatures were set, including one that dated back from 1922 in Temiscaming, where the previous cold of -30.6 C was blown away by the -34.2 C set Thursday.
Val D'Or saw a staggering temperature of -41.6 C, half a degree colder than the previous record, set in 1980.
In Montreal the mercury never got above -24.2 C, far below the average high of -5 C that usually accompanies this date. The coldest January 2 in Montreal recorded history took place in 1968 when it hit -28.3 C, according to Environment Canada.

Средната стойност и варианса НЕ се изчисляват!!!
Т.е. имаш един сет с 24 числа, от -50 до -30. (по едно за всеки кръгъл час).
20 от тия числа са в порядъка от -50 до -40.
4 от тия числа са в порядъка от -40 до -30.
Само 1 от тия числа е МАКСИМУМА на сета, и е равно на -30!
Т.е. дори и да се говори за максимални -30, през 90% от времето е от -40 надолу.
А поне през половината дни дори максималната е -40.
