Question

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

Explanation:

Step1: Observe spread of data

Variability is related to how spread - out the data is. A more concentrated data set has less variability.

Step2: Analyze first dot - plot

The first dot - plot has most of the data concentrated around 25 - 27, with little spread.

Step3: Analyze second dot - plot

The second dot - plot has data more spread out than the first one but still somewhat clustered around the middle values.

Step4: Analyze third dot - plot

The third dot - plot has data extremely spread out, with most of the data at one end (22 - 23) and very little in the other values.

Step5: Analyze fourth dot - plot

The fourth dot - plot has data concentrated around 29 - 31 but with more spread than the first dot - plot.

Answer:

First dot - plot, Fourth dot - plot, Second dot - plot, Third dot - plot
