Question

a survey was conducted among adults in a neighborhood to find out their additional monthly income from side jobs. the data collected was: $410, $420, $415, $430, $425, $410, $425. which dot - plot correctly represents the data?

Explanation:

Step1: Count data frequencies

The data values are $410, 420, 415, 430, 425, 410, 425$. Frequency of $410$ is 2, of $415$ is 1, of $420$ is 1, of $425$ is 2, of $430$ is 1.

Step2: Check dot - plots

Examine each dot - plot to see if the number of dots above each income value matches the frequencies calculated.

Answer:

The dot - plot where there are 2 dots above 410, 1 dot above 415, 1 dot above 420, 2 dots above 425 and 1 dot above 430 is the correct one. Without specific labels for the dot - plots (A, B, C, D), we can't give a letter - based answer, but you can identify it by the described frequencies.
