Question

The central tendency of this data is around _____?

A.) 5
B.) 1
C.) 11
D.) 3

Answer 1

A. 5

Explanation:

The answer is 5, because we find the harmonic mean or weighted average.

Below shown is the weighted sum.

1+4+6+4+20+7+16+11=69

Now we find how many dots, and there is 14 of them.

69/14 is around 5.
