Following is the distribution of marks in Statistics obtained by 32 students :
`{:("Mid - value",5,15,25,35,45,55),("Frequency",4,6,10,7,3,2):}`
Caculate the median marks.

Following is the distribution of marks in Economics obtained by 50 students : {:("Marks (more than)",0,10,20,30,40,50),("Number of Students",50,46,40,20,10,3):} Calculate the median marks . If 60% of the students pass this test , find the minimum marks obtained by a pass candidate.

Calculate mode , given the following data set : {:("Mid - value",15,25,35,45,55,65,75,85),("Frequency",5,8,12,16,28,15,3,2):}

Compute median from the following data : {:("Mid - value",5,15,25,35,45,55,65,75),("Frequency",15,7,11,10,13,8,20,16):}

Following table gives marks in Statistics of the students of a class. Find out mean marks. {:("Mid-value",5,10,15,20,25,30,35,40),("Number of Students",5,7,9,10,8,6,3,2):}

Find the mode of the following frequency distribution of obtained marks of 22 students.

{:("Marks (obtained out of 10)", 4,5,7,8,9,10),("Frequency",5,10,8,6,12,9):} 9 students got full marks. ??

Draw the histogram for the following {:("Class mark ", 25,35,45,55,65),(" Frequency ",7,15,18,12,8):}
