Question

a teacher recorded the time (in minutes) 12 students each spent on a quiz. the results are shown in the dot plot. (a) answer the questions below. is there a cluster from 16 to 19? yes no

Explanation:

Step1: Analyze dot plot clusters

A cluster is a group of data points close together. From 16–19, check dots: 16 (2), 17 (4), 18 (3), 19 (2) – many points here.

Step2: Compare to other ranges

20–21: 0 dots; 22: 1; 23–24: 0. So 16–19 has a dense group (cluster).

Answer:

Yes
