The class mark of the class 120 - 150 is

The Mean of first prime numbers is

The mean of x+3, x - 2, x+5, x+7, x+22 is

The median of 10, 12, 14, 16, 18, 20 is

The median of 12, 13, 16, x+2, x+4, 28, 30, 32 is 23. If x+2, x+4 lie between 16 and 28 then x =

 In a frequency distribution if  $$l=32.5$$   $$f_1=15$$   $$f_0=12$$   $$f_2=8$$   $$h=8$$ then the Mode = 

In a grouped frequency distribution the mid values of a class are used to measure which of the following

Construction of cumulative frequency table is useful in determining the

Which measure of central tendency is given by the X-coordinate of the point of intersection of less than or more than ogive

$$Mode=l+\left(\frac{f_1-f_0}{2f_1-f_0-f_2}\right)\ \times h\ \ then\ f_0\ indicates$$  

If the Mean of the first 'n' Natural numbers is  $$\frac{3n}{5}$$  then n =

If the mode of 3, 2, 7, 5, x, 5, 4, 2 is 2 then x =

The mean of exterior angles of a triangle is

The median of the data of first six prime numbers is

$$If\ the\ median\ of\ a,\ \frac{a}{3},\ \frac{a}{5},\ \frac{a}{4},\ \frac{a}{7}\ is\ 8.\ then\ a=$$  

If 6 observations are given in an ungrouped data in the ascending order then the median is

The less than cumulative frequency curves are drawn using

If the Mean of frequency distribution is 7.5 and $$\Sigma f_ix_i=120+3k,\ \Sigma f_i=30,\ then\ k=$$  

$$Median=l+\left(\frac{\frac{n}{2}-cf}{f}\right)\times h\$$  then  $$cf$$    indicates

The Range of the data 14, 27, 29, 61, 45, 15, 9, 18 is
