150-155
| 160-165
Height (in
cm)
13
10
15
No of
students
The upper limit of the median class in the given data is
a) 165
b) 155
c) 160
d) 170

........Tell with the reason also........​

Answer 1

Answer:

First, arrange your frequency table in ascending order.

Since this question is incomplete as all height (frequency) of class interval is not given. That's why I am only tell you steps to solve this question.

After arranging the class interval. then we see total frequency here it is 60 so we find the average of 30th and 31st term.

The 30th and 31st term can be find by finding cumulative frequency.

After finding the median, the upper value of that median class is the upper Limit of the median Class.
