Question

Determine if the data set is unimodal, bimodal, multimodal, or has no mode, identify the mode(s), if any exist

1, 1, -15, -7, -15, -15, 1
1) no mode
2) unimodal
3) bimodal
4) multimodal

Answer 1

The data set is unimodal with a mode of -15.

Step-by-step explanation:

The data set given is 1, 1, -15, -7, -15, -15, 11.

To determine the mode(s) and whether the data set is unimodal, bimodal, multimodal, or has no mode, we need to identify the value(s) with the highest frequency.

1. To find the mode(s), we can count the frequency of each value in the data set.
   
   The frequency of 1 is 2.
   The frequency of -15 is 3.
   The frequency of -7 is 1.
   The frequency of 11 is 1.
2. The highest frequency is 3, which corresponds to the value -15. Therefore, -15 is the mode of the data set.
3. Since the mode is the only value with the highest frequency, the data set is considered unimodal.
