Solution:
KSEEB SSLC Class 10 Maths Solutions Chapter 13 Statistics Ex 13.4 Q 2.1
To draw ogive of the less than type.
we have to join the points (38, 0), (40, 3), (42, 5), (44, 9), (46, 14), (48, 28), (50, 32), (52, 35).
From the graph, Median is 46.5 kg
KSEEB SSLC Class 10 Maths Solutions Chapter 13 Statistics Ex 13.4 Q 2.2
n = 35 ∴ n2 = 17.5
Class interval which has median is = (46 – 48)
l = 46, n = 35, f = 14, cf = 14, h = 2
KSEEB SSLC Class 10 Maths Solutions Chapter 13 Statistics Ex 13.4 Q 2.3
= 46.5
∴ Median = 46.5 kg.
