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):}`

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):}

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):}

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):}

Construct a histogram for the frequency distribution below: {:("Class Interval",10-20,20-30,30-40,40-50,50-60),("Frequency",6,3,8,4,7):}

The median class in the following frequency distribution is {:("Class interval :",0-10,10-20,20-30,30-40,40-50),("Frequency :",12,13,25,20,10):}

The median class in the following frequency distribution is {:("Class interval :",0-10,10-20,20-30,30-40,40-50),("Frequency :",12,13,25,20,10):}

Calculate mode from the following data : {:("Class Interval",0-10,10-20,20-30,30-40,40-50),("Frequency"," "2," "5," "7," "5," "2):}

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]]

Compute D3 for the following distribution : {:("Marks",0-10,10-20,20-30,30-40,40-50,50-60,60-70,70-80,),("No.of students",3,10,17,7,6,4,2,1,):}

{:("Class Interval",0.10,10-20,20-30,30-40,40-50),("Frequency",5,0,20,5,10):} What is the mean of the above frequency distribution?
