A relative frequency distribution shows percentages summing to $100\%$. If the data set has $40$ items and one category has relative frequency $35\%$, what is the **frequency** (count) for that category?
A$35$
B$4$
C$14$
D$40$
Answer & Solution
Correct answer: C. $14$
Frequency $=$ relative frequency $\times$ total $= 0.35 \times 40 = 14$.
- Trap C confuses percent with count.
- Trap A divides $40$ by $10$ (i.e., $10\%$).
- Trap D returns the total.
