Question

Identify whether the following data set is unimodal, bimodal, multimodal, or has no mode. Assume the data set is a sample and find the modes, if any exist.28,30,23,41,24,35,41,30,35,33,31

Answer 1

1. Order the data:

$23,24,28,30,30,31,33,35,35,41,41$

2. Identify the mode: the number in the data set that occurs most frequently.

For the given data set, the next are the modes:

30

35

41

The three modes have a frequency of 2.

Then, the given data set is polimodal and its modes are: 30, 35 and 41
