Question

find the class size of the class interval 3.5-6.5 ?
​

Answer 1

$\underline {\pink { Class\:size }}$

Difference between the true upper limit and true lower limit of a class interval is called the class size .

$For \:the \: Class \: interval \: 3.5 - 6.5$

• Upper limit = 6.5
• Lower limit = 3.5

$Class \:size = Upper \: limit - Lower \:limit \\= 6.5 - 3.5 \\= 3$

Therefore.,

$\red {Class - size} \green { = 3 }$
