In statistics, the shape of data distribution significantly impacts how data is interpreted and analyzed. Two important distribution shapes are left-skewed (negatively skewed) and right-skewed (positively skewed). Understanding their characteristics, implications, and how they affect data analysis is essential for accurate statistical conclusions.What is Skewness?Skewness measures the asymmetry of a data distribution relative to a
The binomial distribution and the negative binomial distribution are both discrete probability distributions used to model the probability of success in a sequence of independent and identically distributed Bernoulli trials. Both distributions are characterized by the probability of success (p) and the number of trials (n). However, there are some key differences between the two
The negative binomial distribution is a discrete probability distribution that describes the probability of a given number of failures occurring before a given number of successes in a sequence of independent and identically distributed Bernoulli trials. It is often used to model the number of failures that occur before a certain number of successes in
The Weibull distribution is a continuous probability distribution that is commonly used in reliability engineering and statistical analysis. In addition to the two-parameter Weibull distribution, there is also a three-parameter Weibull distribution. The third parameter is the location parameter, also known as the threshold parameter, which determines the point at which the distribution begins. When the
The Bernoulli distribution is a discrete probability distribution that describes the probability of a binary outcome (such as success or failure). It is named after Jacob Bernoulli, a Swiss mathematician.Bernoulli TrialA Bernoulli trial is a statistical experiment with only two possible outcomes: success or failure. Bernoulli trials are often used to model the outcome of a
