Question

What is the cumulative frequency for $4$?

• A. $50$
• B. $60$
• C. $70$
• D. $80$

Answer 1

Answer: (B)

$60$

Score	Frequency	Cummulative Frequency
$1$	$16$	$16$
$2$	$18$	$16+18=34$
$3$	$11$	$34+11=45$
$4$	$15$	$45+15=60$
$5$	$19$	$60+19=79$
$6$	$21$	$79+21=100$

Cumulative frequency can also defined as the sum of all previous frequencies up to the current point.
Here, the cumulative frequency for 4 is $16+18+11+15=60$
