Question

list the four dot plots in order of variability from least to greatest.

Explanation:

Step1: Understand variability in dot - plots

Variability is related to the spread of data points. Data with less spread has less variability.

Step2: Analyze dot - plot a

Dot - plot a has data points spread over a relatively small range (from 10 to 21) with a somewhat even distribution.

Step3: Analyze dot - plot b

Dot - plot b has most of the data points concentrated at one value (22), so it has very low spread and low variability.

Step4: Analyze dot - plot c

Dot - plot c has data points spread over a larger range (from 23 to 30) compared to a and b.

Step5: Order by variability

Based on the spread of data points, the order from least to greatest variability is: b, a, c.

Answer:

b, a, c
