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

Find the median of the following data: {:("Class Interval",0-10,10-20,20-30,30-40,40-50),(f,6,8,5,4,7):}

Caculate the median and mode from the following data : {:("Marks",0-10,10-20,20-30,30-40,40-50,50-60,60-70,70-80),("Number of Students"," "2," "18," "30," "45," "35," "20," "6," "3):}

Find the first decile for the following data: {:("Size", 0.10,10-20,20-30,30-40,40-50,50-60,60-70,70-80),("Frequency "," "2," "18," "30, " "45, " "35, " "20, " "6, " "3):}

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]]

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):}

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,):}

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):}

Find the mean for the following data. {:("Marks obtained",10-20,20-30,30-40,40-50,50-60,60-70),("Number of students",8,6,12,5,2,7):}

Find out the arithmetic mean by the Step-deviation Method of the following: {:("Class Interval",0-10,10-20,20-30,30-40,40-50,50-60,60-70,70-80),("Frequency "," "12," "16," "32," "52," "42," "32," "18," "12):}
