What is the mode of the six values 4, 4, 4, 6, 9 and 9?

Объяснение

The value 4 occurs three times while 9 occurs twice and 6 once, so 4 is the most frequent value and the mode. Answering 9 picks the largest value that repeats, but size plays no part here, since only how often a value occurs decides the mode.
