# Mean Proportional – Explanation, Example, Formula, and FAQs

## What is Mean Proportional?

In mathematics, proportional means that two ratios are equivalent. In other words, given two ratios, a and b, if a / b = c, then a, b, and c are all in proportion. This can be written mathematically as a / b = c ⇔ a = bc.

## Define Mean Proportion

In statistics, the mean proportion is the arithmetic mean of the proportions of a given population. It is also known as the mean value or the expectation of the proportion. The mean proportion is often used to estimate the probability of an event occurring.

## Mean Proportional Example

In statistics, the mean proportional is a measure of central tendency. It is calculated by taking the mean of the reciprocals of the data values and then dividing by the number of data values.

The mean proportional can be used to compare the relative sizes of two or more data sets. It is especially useful for data sets that are not normally distributed.

## Right Angles Mean Proportion

A right angle is a 90 degree angle. A right angle is formed by two perpendicular lines.

## Altitude Rule

The altitude rule states that an aircraft must maintain a certain vertical distance from obstacles. The rule is designed to prevent aircraft from flying too close to obstacles, such as buildings or mountains.

## Leg Rule

The “rule of thumb” is a principle that states that an average person can approximately judge the size of an object by using their thumb as a measurement.

## Mean Proportion Formula

The mean proportion is a formula that calculates the average of a set of proportions. To calculate the mean proportion, divide the sum of the proportions by the number of proportions.

## Importance of Mean Proportional

The mean proportional is an important statistic because it is used to calculate other important statistics, such as the standard deviation. It is also used to determine how much a particular value deviates from the average.

## Solving questions related to Mean Proportional

If the mean proportional of two numbers is 12, then the numbers are 6 and 8.

If the mean proportional of two numbers is 9, then the numbers are 3 and 4.5.
