What is the empirical relationship between mean, median, and mode?
Which of the following cannot be determined graphically?
For a given data with mean 60 and median 50, what is the mode?
The lower limit of the median class of the following data is:\nClass: 0-10, 10-20, 20-30, 30-40, 40-50\nFrequency: 3, 9, 15, 30, 18
If the mean of observations (x, x+3, x+5, x+7,) and (x+10) is 9, then the mean of the last three observations is:
The arithmetic mean of first (n) natural numbers is:
Construction of cumulative frequency distribution table is useful in determining:
If each observation of a raw data is increased by 5, then their mean:
The mode of the data: 15, 14, 19, 21, 14, 15, 14, 28, 16 is:
If the mean of five numbers is 30 and if one number is excluded, their mean becomes 28. The excluded number is:
The class mark of the class interval 20-30 is:
The median of the first 10 prime numbers is:
In the formula for finding the mean of grouped data, (\bar{x} = a + \left(\frac{\sum f_i d_i}{\sum f_i}\right) \times h), (d_i) is given by:
The upper limit of the modal class for the distribution: 0-10, 10-20, 20-30, 30-40, 40-50 with frequencies 5, 12, 20, 15, 7 respectively is:
If the mean of observations (x_1, x_2, \dots, x_n) is (\bar{x}), then the sum of deviations of all observations from their mean is:
What is the median of the data: 10, 12, 14, 18, 20, 22?
For the following distribution, what is the modal class?\nMarks: Below 10, Below 20, Below 30, Below 40, Below 50\nNo. of students: 3, 12, 27, 57, 75
If the mean of (2, 4, 6, 8, x, y) is 5, then:
The midpoint of a class interval is also called:
If the mean of the observations (x, x+2, x+4, x+6, x+8) is 11, then the value of (x) is:
