# The Following Frequency Distribution Table Shows the Distances Travelled by Some Rickshaws in a Day. Observe the Table and Answer the Following Questions - Algebra

Sum

The following frequency distribution table shows the distances travelled by some rickshaws in a day. Observe the table and answer the following questions

 Class (daily distance travelled in km) continuous classes Frequency (no.of. rickshaws) Cumulative frequency less than type 60 - 64 59.5 - 64.5 10 10 65 - 69 64.5 -69.5 34 10+34=44 70 - 74 69.5 - 74.5 58 44+58=102 75 - 79 74.5 - 79.5 82 102+82=184 80 - 84 79.5 - 84.5 10 184+10=194 85 - 89 84.5 - 89.5 6 194+6=200

1) Which is the modal class? Why?
2) Which is the median class and why?
3) Write the cumulative frequency (C.F) of the class preceding the median class.
4) What is the class interval (h) to calculate median?

#### Solution

1) Model class is class that contains highest frequency i.e.
highest frequency = 82
highest frequency class = 75 - 79

2) Median class is the class that contain ("N"/2)^("th") term. Where N is total frequency.
N = 200
("N"/2) = 100
("N"/2)^"th" term will lie  in  (70- 74) class
(i
ii) Cumulative frequency = 44
(iv) Median class = 70 – 74
OR
69.5 – 74.5 (continuous)
h = U.l.  -L.l.
= 74.5 -69.5 = 5
