Question

the dot plot shows the number of pets owned by the students in jayods class. the center, or the middle value, of the data set is

Explanation:

Step1: Count total data points

Count all the dots on the dot - plot. There are 5 + 7+6 + 0+3 + 1=22 data points.

Step2: Determine median position

Since there are 22 data points (an even number of data points), the median is the average of the 11th and 12th ordered data values.

Step3: Find cumulative frequencies

Starting from the left, for 0 pets, there are 5 dots. For 1 pet, there are 7 dots. The cumulative frequency up to 0 pets is 5, and up to 1 pet is 5 + 7=12. So, the 11th and 12th values are both 1.

Step4: Calculate median

The median (middle value) is $\frac{1 + 1}{2}=1$.
