Question

when data is given based on ranges along with their frequencies.find mode​

Answer 1

Answer:

34.28

Step-by-step explanation:

l=30

h=10

f1=12

f0=3

Let f2=0

Put in formula

l+{f1-f0/2f1-f0-f2}h

l+{f1-f0/2f1-f0-f2}h30+{12-3/2×12-3-0}10

l+{f1-f0/2f1-f0-f2}h30+{12-3/2×12-3-0}1030+{9/24-3-0}10

l+{f1-f0/2f1-f0-f2}h30+{12-3/2×12-3-0}1030+{9/24-3-0}1030+{9/21}×10

$30 + \frac{9}{21}$

$\frac{630 + 90}{21}$

$\frac{720}{21}$
