Mode of 1, 2, 2, 3, 4?

Explanation

• The mode is the value that appears most often, and 2 appears twice while every other number appears once.
• Tally the data first, because the mode depends on frequency and not on size.
• The median of this set is also 2, but the ideas differ: median is the middle value, mode is the most frequent value.
• The mean is (1 + 2 + 2 + 3 + 4) ÷ 5 = 2.4, which shows the three averages need not agree.
• A data set can have two modes, or no mode at all when every value appears equally often.
