Which of the following would indicate that a dataset is skewed to the right? A) The interquartile range is larger than the range. B) The range is larger than the interquartile range. C) The mean is much larger than the median. D) The mean is much smaller than the median.

In probability theory and statistics skewness is a measure of the asymmetry of the probability distribution of a real-valued random variable about its mean . The skewness value can be positive zero negative or undefined. For a unimodal distribution negative skew commonly indicates that the tail is on the left side of the distribution and positive skew indicates that the tail is on the right .

In statistics a quartile is a type of quantile which divides the number of data points into four parts or quarters of more-or-less equal size.The data must be ordered from smallest to largest to compute quartiles; as such quartiles are a form of order statistic.The three main quartiles are as follows: splits off the lowest 25% of data from the highest 75%

In statistics the number of degrees of freedom is the number of values in the final calculation of a statistic that are free to vary.. The number of independent ways by which a dynamic system can move without violating any constraint imposed on it is called number of degrees of freedom.

In statistics the Pearson correlation coefficient (PCC pronounced / ˈ p ɪər s ən /) also referred to as Pearson's r the Pearson product-moment correlation coefficient (PPMCC) or the bivariate correlation is a mea...
