A recent survey asked 874 people to identify what education they have achieved. The accompanying table summarizes the results. Does this table describe a relative frequency distribution? Why or why not?
Education------------------Percent
No Diploma----------------35%
GED Diploma-------------65%
High School Graduate--56%
Some College-------------48%
Associate Degree--------8%
Bachelor's Degree-------27%
Graduate Degree---------9%

The answer is c. No, the sum of the percentages is not 100 percent.
To determine if the table describes a relative frequency distribution, we need to check if the sum of the percentages adds up to 100 percent. In this case, the sum of the percentages is 35% + 65% + 56% + 48% + 8% + 27% + 9% = 238%. Since the sum is greater than 100 percent, this table does not represent a relative frequency distribution.
A relative frequency distribution is a table that displays the percentage or proportion of observations in each category of a categorical variable. The percentages in the table should add up to 100 percent because they represent the relative frequencies of each category. In this case, the sum of the percentages exceeding 100 percent indicates that the data is not properly represented as a relative frequency distribution.
