The percentage of marks obtained by 100 students in an examination are as follows: Marks 130-135 135-140 140-145 145-150 150-155 155-160 160-165 Frequency 14 16 18 23 18 8 3 The cumulative frequency of the class interval 140 – 145 is

In the given data if n = 44, l = 400, cf = 8, h = 100, f = 20, then its median is

The measure of central tendency that can be obtained graphically is

For the following distribution Class 60-70 70-80 80-90 90-100 100-110 Freq 13 10 15 8 11 the upper limit of the median class is

Consider the data Class 65-85 85-105 105-125 125-145 145-165 165-185 185-205 Freq 4 5 18 20 17 7 4 The difference of the upper limit of the median class and the lower limit of the modal class is

For a symmetrical distribution

The middle most value of the data is

The numbers 5, 7, 10, 12, 2x – 8, 2x + 10, 35, 41, 42, 50 are arranged in ascending order. If their median is 25, then the value of ‘x’ is
