Given data, which represents the marks of the students in a particular subject,
was represented in the form of a 'less than type ogive' and 'more than type ogive',
as shown
(5,7)
(1) How do you identify the curves 'less than type ogive' and 'more than type
ogive' by looking at in terms of increasing order of curve or decreasing order
of curve?
(u) If the two curves meet at the point (5, 7). Then what is the median of the
data?
(iii) If mode of the data is 7, find the mean of the data.
Answers
Median of Data will by 5 , Mean will be 4
Step-by-step explanation:
'less than type ogive will be in ascending order
more than type ogive' will be in Descending order
If the two curves meet at the point (5, 7).
Median is given by the x-coordinate of the point of intersection of the more than ogive and less than ogive
then Median of Data will by 5
Total Number of Students would be 13
Median = 5
Mode = 7
Mode = 3 median - 2 mean
=> 7 = 3 * 5 - 2 Mean
=> 2 Mean = 8
=> Mean of the Data = 4

mean of the data = 4
Answer:
Thus, the empirical relationship between the three measures of central tendency is 2 Mean = 3 Median – Mode. Hence, option (a) is the correct answer.
