The relative frequency of respondents for a sample of 313 people who identified as Democrat, Republican, or Independent can be calculated by dividing the number of respondents for each group by the total number of respondents (313).
For example, if 100 respondents identified as Democrat, the relative frequency of Democrats would be 100/313, or approximately 32%. If 125 respondents identified as Republican, the relative frequency of Republicans would be 125/313, or approximately 40%. If the remaining 88 respondents identified as Independent, the relative frequency of Independents would be 88/313, or approximately 28%.
Therefore, the relative frequency of respondents in the sample of 313 people would be 32% Democrat, 40% Republican, and 28% Independent.
