QUARTILES FOR GROUPED DATA
To find 𝑄1, 𝑄2, and 𝑄3, we first need to determine the 𝑄1, 𝑄2,
and 𝑄3 classes, respectively. The 𝑄1 class is the class interval
where the (𝑁/4)𝑡ℎ data is contained. The 𝑄2 class is the class
interval where (2N/4𝑁)𝑡ℎ data is contained. The 𝑄3 class is the
class interval where (3N/4)𝑡ℎ data is contained.

CALCULATE FOR Q2
To find 𝑄2, we first need to determine the 𝑄2, class, The 𝑄2
class is the class interval where (2N/4)𝑡ℎ data is contained.
CALCULATE FOR Q2
CALCULATE FOR Q3
To find 𝑄3, we first need to determine the 𝑄3, class, The 𝑄3
class is the class interval where (3N/4)𝑡ℎ data is contained.
