If a constant is added or substracted from the values of a variable, then how their median and mode are changed?

If the values of a variable are multiplied or divided by constant, then how their median and mode are changed?

How AM, GM and HM of the values of a variable are changed when the values are divided by a constant .

Find the median of the values of the variable given in the question number 10 in the exercise -1.

The sum of the deviations of the values of a variable from its ____ is zero.

If the value of a variable are 4, 4, 3, 3, 4, 1, 2 then find the value of mode and median.

What is the algebraic sum of the deviations of the values of a variable from their average ? Explain with an example.

Express the following statements in the form of simultaneous linear equations and solve them by drawing graphs : (iii) If 3 is subtracted from the numerator and 2 is added to the denominator of a fraction it becomes (1)/(3) . Again, if 4 is substracted from the numberator and 2 is subtracted form the denominator of the same fraction, it becomes (1)/(2) . Determine the fraction.

If the sum of the squares of the differences of the 10 values of a variable from its mean 50 be 250, find the coefficient of variation.
