Identify these two definitions among the following options. Choose 2 answers: Choose 2 answers:

The key understanding here is that there isn't a single way to define "engagement." The number of likes can be a good measure of that. The number of comments is also a good measure. The numbers of views or shares can also be good measures, but we are not given information about that.

Now let's go over the options and see which of them might be used to describe "user engagement per a single writer."

Definition Analysis Appropriate?

Average number of likes per writer "Number of likes" is a measure of user engagement. Taking the average per writer makes a good definition.

YES

Total number of comments "Total number of comments" is a measure of user engagement, but without taking the average per writer, this is not a good definition.

NO

Average number of words per writer "Number of words" isn't a measure for user engagement.

NO

Average number of comments per writer "Number of comments" is a measure of user engagement. Taking the average per writer makes a good definition.

YES

We are left with two definitions for user engagement per a single writer:

Average number of likes per writer

Average number of comments per writer

Let's calculate the user engagement per a single writer for each website according to each definition:

Website Definition #1 Definition #2

A 77{,}000\,\dfrac{\text{likes}}{\text{writer}}77,000

77, comma, 000, start fraction, start text, l, i, k, e, s, end text, divided by, start text, w, r, i, t, e, r, end text, end fraction 11{,}000\,\dfrac{\text{comments}}{\text{writer}}11,000

11, comma, 000, start fraction, start text, c, o, m, m, e, n, t, s, end text, divided by, start text, w, r, i, t, e, r, end text, end fraction

B 63{,}636.\overline{36}\,\dfrac{\text{likes}}{\text{writer}}63,636.
