The first decile is the 10th percentile (P10). It means 10% of the data is less than
or equal to the value of P10 or Di and so on. In our example above P10 = 3, P20 = 4,
and so on as the arrow indicated.

Problem 1.
In a grade 7 MAPEH class, the weights of the students are the following: 57,
40, 55, 45, 56, 52, 48, 50, 41, 51, 50, 53, 48, 55, 38, 55, 52, 56, 51, 54. Find Q3, D4,
and P70.
Solution:
a. Arrange the data in ascending order.
-
b. The least value in the data is
c. The median of the data
d. The upper quartile (Q3) is halfway from the median to the greatest data value.
and the greatest value is
Q3 =.
e. Fourth decile (D4) is the fourth part of the distribution divided into ten equal parts.
So D4 =
f. P70 is just equal to D7, therefore P70 =
