What are Mutually Exclusive Events? In statistics and probability theory, two events are mutually exclusive if they cannot occur at the same time. The simplest example of mutually exclusive events is a coin toss. A tossed coin outcome can be either head or tails, but both outcomes cannot occur simultaneously. Mutually exclusive events are commonly…
What is the Net International Investment Position (NIIP)? The Net International Investment Position (NIIP) is the balance value when external assets are adjusted for external liabilities. The external assets are the foreign assets owned by the country’s government, companies, and citizens. The external liabilities are the foreigners-owned domestic assets.

What is a Frequency Polygon? A frequency polygon is a visual representation of a distribution. The visualization tool is used to understand the shape of a distribution. Essentially, the frequency polygon indicates the number of occurrences for each distinct class in the dataset. In addition, the graph may be used to show the cumulative frequency…
What is Cumulative Frequency Distribution? Cumulative frequency distribution is a form of frequency distribution that represents the sum of a class and all classes below it. Remember that frequency distribution is an overview of all distinct values (or classes of values) and their respective number of occurrences. The cumulative frequency distribution is extremely helpful when…
What is a Bell Curve? A bell curve is the informal name of a graph that depicts a normal probability distribution. The term obtained its name due to the bell-shaped curve of the normal probability distribution graph. However, the term is not quite correct because the normal probability distribution is not the only probability distribution…
What is a Positively Skewed Distribution? In statistics, a positively skewed (or right-skewed) distribution is a type of distribution in which most values are clustered around the left tail of the distribution while the right tail of the distribution is longer. The positively skewed distribution is the direct opposite of the negatively skewed distribution. Central…
What is a Negatively Skewed Distribution? In statistics, a negatively skewed (also known as left-skewed) distribution is a type of distribution in which more values are concentrated on the right side (tail) of the distribution graph while the left tail of the distribution graph is longer. While normal distribution is the most commonly encountered type…
