Solution by Steps
step 1
Identify the clusters, gaps, and peaks in the dot plot. The dot plot shows the following distribution: one dot at 19°C, two dots at 20°C, four dots at 21°C, seven dots at 22°C, six dots at 23°C, four dots at 24°C, and one dot at 25°C
step 2
Determine if there is a data point very far from the center. The data points range from 19°C to 25°C, with the center around 22°C. There are no data points that are very far from this center
step 3
Identify the peak in the distribution. The highest frequency of data points is at 22°C, with seven dots
Answer
B
Key Concept
