Given below is the frequency distribution of the heights of 50 students of a class: Class Interval:, 140-145, 145-150, 150-155, 155-160, 160-165 Frequency:, 8, 12, 18, 10, 5 Draw a histogram representing the above data.

Consider the following frequency distribution of the height of 60 students of a class: The upper limit of the median class in the given data is:

Find the unknown entries (a,b,c,d,e,f,g) from the following frequency distribution of heights of 50 students in a class: Class intervals (heights in cm) Frequency Cumulative Frequency 1250-155 155-160 160-165 165-170 170-175 175-180 12 b 10 d e 2 a 25 c 43 48 f Total g

Find the mean of the following frequency distributions: Class interval: 25-35 35-45 45-55 55-65 65-75 Frequency: 6 10 8 12 4

The heights (in cm) of 9 students of a class are 148,144,152,155,160,147,150,149,145. find the median height.

Find the mean of the following frequency distributions: Class interval: 10-30 30-50 50-70 70-90 90-110 110-130 Frequency: 5 8 12 20 3 2

Caculate median of the following distribution of data : {:("Class Interval",1-10,11-20,21-30,31-40,41-50),("Frequency"," "4," "12," "20," "9," "5):}

If the median of the following frequency distribution is 28.5 find the missing frequencies: Class interval: 0-10 10-20 20-30 30-40 40-50 50-60 Total Frequency: 5 f_1 20 15 f_2 5 60

The heights (in cm) of 9 students of a class are as follows: 150, 160, 140, 140, 150, 140, 150, 144, 148 Find the median of this data.

For the following frequency distribution, determine the mode and the median: {:("Class",100-120,120-140,140-160,160-180,180-200),("Frequency",12,14,8,6,10):}

Given below is a cumulative frequency distribution showing the mars secured by 50 students of a class From the frequency distribution table for the data.
