For the follwing frequency distribution draw a cumutalive frequency curve of 'more than type' and hence obtain the median value `[[Class,0-10,10-20,20-30,30-40,40-50,50-60,60-70],[Frequency,5,15,20,23,17,11,9]]`

For the following frequency distribution draw a cumulative frequency curve of "'more than type'" and hence obtain the median value [["Class",0-10,10-20,20-30,30-40,40-50,50-60,60-70],["Frequency",5,15,20,23,17,11,9]]

Draw a frequency curve for the data given below: {:("Class Interval",0-10,10-20,20-30,30-40,40-50,50-60,60-70),("Frequency",3,2,4,6,9,7,10):}

For the given distribution, draw the less than and greater than cumulative frequency curves. {:("Class Interval",0-10,10-20,20-30,30-40,40-50,50-60,60-70,70-80),("Frequency",5,3,7,2,14,9,15,10):}

Find the mean deviation from the mean of the following data: Classes:,10-20,20-30,30-4040-50,50-60,60-70,70-80 frequency,2,3,8,14,8,3,2

Estimate the mode of the following data from the histogram. {:("Class Interval",0-10,10-20,20-30,30-40,40-50,50-60,60-70,70-80),("Frequency",8,10,15,16,20,13,14,12):}

In the following frequency distribution, the frequency of the class interval (40-50) is not known. Find it, if the arithmetic mean of the distribution is 52. {:("Wages(Rs.)",10-20,20-30,30-40,40-50,50-60,60-70,70-80),("Number of Workes"," "5," "3," "4," "?," "2," "6," "13):}

Find the value of frequecies in the following frequency distribution table, if n=100 and median is 32 [[Marks,0-10,10-20,20-30,30-40,40-50,50-60,Total],[Number of student,10,x,25,30,y,10,100]]

The mode from given grouped data would be {:("Class Interval",10-20,20-30,30-40,40-50,50-60),("Frequency",5,7,6,8,4):}
