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):}

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):}

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):}

Find the missing frequency of the group 20-30 when the median is 28. {:("Class Interval",0-10,10-20,20-30,30-40,40-50),("Frequency"," "5," "8," "?," "16," "6):}

Write the median class of the following distribution: Classes: 0-10 10-20 20-30 30-40 40-50 50-60 60-70 Frequency: 4 4 8 10 12 8 4

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):}
