Question

This data set has two modes. Find the second mode of the data. 18, 12, 19, 15, 19, 18, 6 Mode: 18, [?]

Answer 1

The mode of a dataset is the data that happens most frequently. A dataset has more then one mode when the most frenquet data values happens the same number of times.

Let's put the dataset in ascending order:

`18,12,19,15,19,18,6\to6,12,15,18,18,19,19`

As we can see, most data happens once and 18 and 19 happens twice each. So, both are the modes.

Since the given one is 18, the second mode is 19.
