Here you will learn logs change of base formula in logarithm and logarithmic inequalities with example. Let’s begin – Logs Change of Base Formula – Base Changing Theorem It can be stated as “quotient of the algorithm of two numbers is independent of their common base.” Symbolically, \(log_b m\) = \(log_a m \over log_a b\), …
Here you will learn mean square deviation formula and relation between mean square deviation and variance with example. Let’s begin – Mean Square Deviation Formula The mean square deviation of a distribution is the mean of the square of deviations of variate from assumed mean. It is denoted by \(S^2\). Hence \(S^2\) = \(\sum{x_i – …
Here you will learn how to find total number of combinations and distribution of distinct objects and alike objects. Let’s begin – Total Number of Combinations (a) Given n different objects, the number of ways of selecting at least one of them is, \(^{n}C_1\) + \(^{n}C_2\) + \(^{n}C_3\) +…….+ \(^{n}C_n\) This can also be stated …
