A survey of 30 people was conducted about how many siblings they had. A graph was created that showed the percentage of the survey group, which had each number of siblings. The "frequency" column in the table shows the number of responses that having a certain number of siblings received. Using appropriate and precise statistical terminology, describe the distribution and provide an explanation for the distribution being a certain way.
