L= lower class boundary of the modal group

f

1

= frequency of the modal group

f

0

= frequency of the class preceding or just before the modal class

f

2

= frequency of the class succeeding or just after the modal class

w= group width

mode = 8000+

2×300−240−50

300−240

×2000

mode= 8000+387.096

mode = 8387.096

mode = 8350

Answer 2

Answer:

where is the graph?...............
