It often eliminates outliers and anomalies from data representation completely.

It can provide more reliable insights into actual transportation trends among students.

It makes it possible to use pie charts instead of frequency tables.

It decreases overall accuracy since there could be more recording errors.

All flavors have an equal probability of being chosen.

It cannot be determined without knowing all probabilities.

It has the highest probability of being chosen.

It has the lowest probability of being chosen.

The percentages in a relative frequency table are obtained by multiplying the frequencies by 100.

The relative frequency table provides the actual counts for each category.

The sum of the relative frequencies in a relative frequency table is always 100

The relative frequency table is used to display qualitative data only
