Question

2. Which best describes

(a) No peaks
(c) Two peaks
the shape of a unimodal distribution?
(b) One peak
(d) More than two peaks

Answer 1

(b) One peak

Explanation:

If you are referring to a unimodal distribution, it will only have one peak.

Mode of a dataset is the value that occurs most frequently. There can be more than one mode.

* If there is only one mode, then it is called a unimodal distribution and wlll have only one peak

* If there are two modes then it is a bimodal distribution and will have two peaks

* If there are more than 2 modes, then it is a multimodal distribution and has than 2 peaks - as many peaks as modes

* If there is no mode then no peaks

Here are examples
1, 2, 3, 4, 5 No mode, no peaks

1, 2, 2, 3, 4, 5 Unimodal with mode = 2, one peak

1, 2, 2, 3, 3, 4, 5 Bimodal with 2 modes 2 and 3 so two peaks

1, 1, 2, 2, 3 , 3, 4, 5 Multimodal with 3 modes so more than 2 peaks

Answer 2

A, im pretty sure at least. You didnt provide much context.
