A variable is a letter or symbol that stands for a number and is used in mathematical expressions and equations.z∗ = complex conjugate of z. z ∗ = complex conjugate of z. The Hat symbol can be used to denote a vector. And the Star symbol may possibly used to denote a binary operation. For example a non empty set with a binary operation is said to be a Group if..... , its dual space, , is the set of linear maps .The data follows a normal distribution with a mean score (M) of 1150 and a standard deviation (SD) of 150. Following the empirical rule: Around 68% of scores are between 1,000 and 1,300, 1 standard deviation above and below the mean. Around 95% of scores are between 850 and 1,450, 2 standard deviations above and below the mean.There are several formulas to measure skewness. One of the simplest is Pearson’s median skewness. It takes advantage of the fact that the mean and median are unequal in a skewed distribution. Pearson’s median skewness =. Pearson’s median skewness tells you how many standard deviations separate the mean and median.
